PREFACE vii Diversity Mango (Mangifera) in Indonesia is an important and interesting aspect to be studied for mango improvement program relies heavily on the genetic diversity available. Exploration and surveys of mango genetic diversity in Indonesia have been conducted in Java (Fitmawati 2003, Sulistiowati (1989), West Kalimantan and South Kalimantan (Kostermans and Bompart 1989), South Sulawesi (Wirawan 1999), Southeast Sulawesi (Fitmawati 2005) exploration and surveying the diversity of mango species in eastern and southern Sumatra has never been done.It is very important to do exploration to reveal the biological wealth of Sumatran mangoes in order to sow the resources of germplasm of wild mangoes in Sumatra that are racing with the rapid transfer of land function to the area of oil palm and rubber plantation. Mango has become a major fruit crop of the tropics and subtropics, particularly in Asia, where the mango has always been the most important fruit crop and where it has been considered the ‗king of fruits‘ (Purseglove, 1972). However, improvement of tree crops has lagged far behind field crops for several reasons: their heterogeneity, polyploidy, lengthy juvenile period, time required for evaluation of trees in the fi eld, and the relatively high cost of maintaining tree plantings. For the most part, fruit cultivars continue to be ancient selections, many of which have serious problems, including alternate bearing, lack of disease resistance, low yields, etc. The rapid growth of mango production in recent years has been due to its expansion into new growing regions of the New World, China and parts of Africa; the planting of regular bearing selections; and the adoption of modern fi eld practices, which include irrigation management, control of flowering, etc. Agricultural practices are currently undergoing another revolution, as integrated pest and disease management replaces viii the earlier reliance on agrichemicals, and emerging fields within biotechnology begin to impact cultivar development. The Mangifera species have their centre of diversity and origin in South-east Asia, a region that has experienced great economic development in recent years. Vast wooded areas have been completely or partially deforested either for expanding agriculture or for removal of tropical hardwoods for export. This has caused great genetic erosion within many species and genera. The Mangifera species, like many other tropical fruit trees, are canopy and emergent trees of the tropical rainforest (Kaur et al., 1980). These trees are widely scattered in the tropical rainforest, flower erratically and reproduce from large seeds that deteriorate rapidly. As such, they are particularly vulnerable and in danger of extinction. Mango (Mangifera indica L.) has attained the status of most important fruit crop in tropics and subtropics, particularly in Asia and considered as ‗king of fruits‘. India occupies first place in mango production of the world and accounts for almost half of the global production and area. India being primary and secondary centre of domestication of Mangifera indica, substantial contribution of mango industry in economy, export, livelihood support is well known. Enormous genetic diversity exists in the country. Considering the importance of mango national database on mango has been developed with the support of DBT (Department of Biotechnology, Government of India, New Delhi) in network mode involving ten research institutes/universities viz., Central Institute for Subtropical Horticulture (CISH), Lucknow; Indian institute of Horticultural Research (IIHR), Bengaluru; Horticultural College & Research Institute for Women (HCRIW) (Tamil Nadu Agricultural University), Trichy; Bidhan Chandra Krishi Viswavidyalaya (BCKV), Nadia; National Research Centre for Litchi (NRCL), Muzaffarpur; Central Horticultural Experiment ix Station (CHES), Bhubaneswar; Fruit Research Station (FRS) (Andhra Pradesh Horticultural University), Sangareddy; Regional Fruit Research Station (RFRS) (Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth), Vengurle; Agriculture Experimental Station (AES) (Navsari Agriculture University), Paria and ICAR Research Complex for NEH Region (ICAR RC), Barapani. As the information on morphological characterization of regional farmer‘s variety and eco-geographical adaptations, package of practices, traditional knowledge, geographical indicators related to different varieties specific to mango growing areas of India, thus the involvement of these institutions for collection of information at district level resulted a huge data set representing country level information, which further reorganized for the development of an interactive and informative national network database meeting the strong need of the country. All centres collected geographical location specific information and final integration of the digitized information developed at Central Institute for Subtropical Horticulture (CISH), Lucknow as National Mango Database. Mango database providing information on genetic, phenotypic, molecular markers, proteins, endogenous phytochemicals, usage, packages of practices, traditional knowledge, nutritional and medicinal value, production, harvesting and postharvest technologies, on farm conservation sites, gene bank status, IPR issues, diseases and pests, geographical indicators, bibliographic records and GIS applications for georeference database and several other important aspects on the crop. The national database on various aspects of mango germplasm would be highly useful for biotechnologists, students, researchers, farmers, policy makers and mango lovers. From IPR point of view, utilization of germplasm in breeding programs and other biotechnological researches on mango will be highly useful. x Genetic resources molecular characterization and bioinformatics resource information including nucleic acid, ESTs, proteins, chemicals of different Mangifera collected by CISH, Lucknow. CISH, Lucknow also generated information on GIS based mapping of thematic areas like genetic diversity, molecular information and varietal climate suitability, database useful for DUS testing, IPR issues including patents on mango. Development and maintenance of national database containing information on various aspects related to mango will result in proper utilization of genetic resources in improvement programmes and germplasm conservation, which will also provide sustainable management tools. Mango database also delivers information on various aspects like improvement, production technology, crop protection, biotechnology, genetics, bibliographic citations and related issues affecting livelihoods and nutritional security for the benefit of researchers, farmers, local communities and tropical fruit tree user groups. Information on mango accessions available in different gene banks was augmented and updated for providing information of the accessions from various parts of the country. Existing documentation available on mango have been converted into digital format. Information on the farmer‘s varieties and landraces, available in the literatures were digitized for the updates of database. For this purpose, descriptions made by research workers from different parts of the country were collected. Information on the important eco-geographical areas rich in genetic diversity presented could also

Biodiversitas 18: 715-719. Northern Sumatra is an area with geographical variation. The environmental factors are affected on character plasticity such as found in Anacardiaceae family especially Mangifera genus. The character plasticity of Mangifera members raises a problem in determining clear boundaries between species based on morphological character. Therefore, a molecular approach is necessary to provide a specific character among Mangifera species. This study aimed to reconstruct the phylogeny among Mangifera members in Northern Sumatra based on the sequences of trnL- F intergenic spacer. All of the sequences were aligned by using Clustal W and Cladogram was reconstructed by using PAUP by Maximum Parsimony (MP) and Neighbour-Joining (NJ) methods. The MP cladogram produced two in groups i.e., clade I consist of M. odorata1, M. odorata2, M. laurina1, M. laurina2, M. indica, M. zeylanica, M. quadrifida and Mangifera sp. and clade II consisted of M.

Many assertions in the literature about the origins of particular species are found to be without empirical basis. In the absence of other data, comparative linguistics is an important source for tracing the spread of some fruits. Contrary to the Pacific, it seems that many of the fruits we now consider characteristic of the region may well have spread in recent times. INTRODUCTION empirical base for Pacific languages is not matched for mainland phyla such as Austroasiatic, Daic, Sino- This study 1) is intended to complement a previous Tibetan or Hmong-Mien, so accounts based purely paper on the history of tree-fruits in island Southeast on Austronesian tend to give a one-sided picture.

  • Collection and Evaluation of Under-Utilized Tropical and Subtropical Fruit Tree Genetic Resources in Malaysia
    J]RCAS International Symposium Series No. 3: 27-38 Session 1-3 27 Collection and Evaluation of Under-Utilized Tropical and Subtropical Fruit Tree Genetic Resources in Malaysia WONG, Kai Choo' Abstract Fruit tree genetic resources in Malaysia consist of cultivated and wild species. The cul­ tivated fruit trees number more than 100 species of both indigenous and introduced species. Among these fruits, some are popular and are widely cultivated throughout the country while others are less known and grown in small localized areas. The latter are the under-utilized fruit species. Apart from these cultivated fruits, there is also in the Malaysian natural forest a diversity of wild fruit tree species which produce edible fruits but are relatively unknown and unutilized. Many of the under-utilized and unutilized fruit species are known to show economic potential. Collection and evaluation of some of these fruit tree genetic resources have been carried out. These materials are assessed for their potential as new fruit trees, as sources of rootstocks for grafting and also as sources of germplasm for breeding to improve the present cultivated fruit species. Some of these potential fruit tree species within the gen­ era Artocarpus, Baccaurea, Canarium, Dimocarpus, Dialium, Durio, Garcinia, Litsea, Mangif era, Nephelium, Sa/acca, and Syzygium are highlighted. Introduction Malaysian fruit tree genetic resources comprise both cultivated and wild species. There are more than 100 cultivated fruit species of both major and minor fruit crops. Each category includes indigenous as well as introduced species. The major cultivated fruit crops are well known and are commonly grown throughout the country.

Some of these have per- sisted throughout the centuries and are those which refer to the simple colors or ranges such as red or yellow. As the language developed, more and more color names were invented to describe the colors used by art and industry and in late years in the rapidly expanding field of sales promotion. Some of these refer to the pigment or dye used, as Ochre Red or Cochineal, or a geographical location of its source such as Naples Yellow or Byzantium. Later when it became clear that most colors are bought by or for women, many color names indicative of the beauties and wiles of the fan- sex were introduced, as French Nude, Heart’s Desire, Intimate Mood, or Vamp. Fanciful color names came into vogue such as Dream Fluff, Happy Day, Pearly Gates, and Wafted Feather. Do not suppose that these names are without economic importance for a dark reddish gray hat for Milady might be a best seller ; if advertised as Mauve Wine whereas it probably would not if the color were called Paris Mud.

The genus Bouea has three species B. Marcophylla, B. oppositifolia, and B. poilanei. Morphological variations were found in Bouea in various regions of Indonesia. This study aims to review the genetic diversity and grouping of Bouea spp in Indonesia using morphological markers. A total of 75 accessions of B. macrophylla and 30 accessions of B. oppositifolia obtained from 13 provinces in Indonesia observed with variations using 31 and 81 characters, respectively as morphological markers. Result of the observations were then cluster analyzed using the program NTSYS version 2.02 and confirmed using principal component analysis (PCA). Results revealed that morphological markers which can distinguish Bouea from other plants were opposite leaves pattern and purle seeds. Morphological markers that distinguished B. macrophylla with B. oppositifolia were leaf size, fruit size, fruit shape, fruit color, flesh color, and shape of the leaf axillary bud. Cluster analysis showed that B. macrophylla has similarity coefficient of 0.77 to 1.00 which is sub-divided in seven major groups with coefficient of 0.93.

    Technical Guidelines for Reforestation at Ex-Coal-Mining Areas - Based on the outcomes of experimental reforestation activities at ex-coal-mining areas in South Kalimantan, Indonesia - Japan International Forestry Promotion and Cooperation Center (JIFPRO) March 2015 Technical Guidelines for Reforestation at Ex-Coal-Mining Areas - Based on the outcomes of experimental reforestation activities at ex-coal-mining areas in South Kalimantan, Indonesia - Eiichiro Nakama, Seiichi Ohta, Yasuo Ohsumi, Tokunori Mori and Satohiko Sasaki Japan International Forestry Promotion and Cooperation Center Fakhrur Razie, Hamdani Fauzi and Mahrus Aryadi Lambung Mangkurat University, Indonesia Japan International Forestry Promotion and Cooperation Center March 2015 Foreword During the past decades, deforestation and forest degradation continues especially in developing countries. According to the report of the Food and Agriculture Organization of the United Nation (FAO), approximately 13 million hectors of global forests have been lost annually due to forest land conversion to other land uses, forest fires and natural disasters, while reforestation and natural regeneration account for an increase of approx. 7.8 million hectors of forest cover. This means the net loss of global forest is estimated at 5.2 million hectors. Adverse impacts of forest conversion to farmland can be minimized as far as the land is properly used and managed in a sustainable manner. However, in some cases, problem soils are exposed and abandoned as degraded land. Deforestation by mining is a big issue these years. Problem soils such as strong acid soils and/or too much heavy metal soils appear at the ex-mining areas. In some cases it is too difficult to reforestate.
