Eric A. Kueneman Chief Crop and Grassland Service FAO Plant Production and Protection Division FARMERS’ KNOWLEDGE OF WILD MUSA IN INDIA vii FOREWORD India is a treasure chest of biodiversity that hosts a large variety of plants and animals. It has been one of the major centres of origin and distribution for both wild and cultivated bananas (Musa spp.), especially for balbisiana-derived hybrids. Due to the antiquity of bananas in India, their great diversity and long history of domestication, bananas are interwoven with national heritage and culture and have great socio-economic significance. The rich genetic diversity is an irreplaceable resource, providing materials for introduction, domestication and improvement programmes as well as opportunities for the search and selection of Musa genotypes resistant to pests and diseases. The broad genetic pool maintained by farmers can be used for future banana crop improvement as banana is essentially a clonally propagated crop with many sterile species, which makes progress through conventional breeding slow and difficult. Due to the limited number of landraces and commercial varieties available and their asexual reproduction, bananas have a narrow genetic pool that makes them vulnerable to pests and diseases. As a result, new breeding methods and tools, including biotechnology and mutation breeding, will be helpful to develop resistant bananas for cultivation without the threat of genetic drift. The Food and Agriculture Organization of the United Nations (FAO) is committed to preserving agricultural biodiversity as a way of helping people develop a suitable livelihood base for their own resources. The Organization has long been concerned with conservation and sustainable use issues, which have been the focus of various Regular Programme work and field-based activities. With regard to bananas, FAO is concerned about the disappearance of wild bananas and how human presence and expansion affect their biology, especially in Southeast Asia. The Organization calls for greater use of genetic diversity for strengthening breeding programmes in developing countries and for promoting awareness of the inevitable consequences of a narrow genetic base in crops and the need for a broader genetic base, especially in the case of commercial bananas. The present case study provides an insight into the indigenous technical knowledge regarding multiple uses of wild and cultivated bananas for the benefit and advantage of the local population in India. The study provides a picture of distribution of wild and cultivated Musa species of interest in the country; it sets out the vital role of local knowledge in conserving biodiversity and ecosystem function in the different agro-ecological zones of India where Musa species occur. The study also describes in detail the involvement of the tribal and farming communities in the conservation, maintenance, perpetuation and

  • Utilising Local Cuisine to Market Malaysia As a Tourist Destination
    Available online at www.sciencedirect.com ScienceDirect Procedia - Social and Behavioral Sciences 144 ( 2014 ) 102 – 110 5th Asia Euro Conference 2014 Utilising local cuisine to market Malaysia as a tourist destination Mohd Hairi Jalisa,* , Deborah Chea, Kevin Markwellb aSouthern Cross University, Locked Mail Bag 4, Coolangatta QLD 4225, Australia bSouthern Cross University, Military Road (PO Box 157), East Lismore NSW 2480, Australia Abstract Travelling to a tourism destination can be made more exciting by experiencing the local cuisine. The variety of cooking methods and colourful ingredients blend together in a hot wok to create signature dishes of particular cuisines. Nevertheless, a cuisine needs to be clearly defined by definite individual characteristics so it is recognised. The primary objective of this study is to understand how Malaysian cuisine is used in marketing Malaysia as a tourist destination. Content analysis is used on selected Malaysian cuisine promotional materials such as brochures, travel guides, and webpages to extract relevant data. Results show that “close-up meal” had the highest image count from among the eight categories identified. As for text, ten categories were identified. “Creating desire” topped the list, followed by “sensory appeal”. The Malaysian Government is particular in the details selected for images of and narrative on the local cuisine. As a result, the marketing collateral could provide excitement and help tourists to anticipate the type of food experience that they can find when travelling in Malaysia. Additionally, it could help understanding what Malaysian cuisine is and develop the brand image. © 20142014 ElsevierThe Authors. Ltd. ThisPublished is an open by Elsevier access articleLtd.

  • A Look at Ornamental Bananas Esendugue Greg Fonsah, Richard Wallace, and Gerard Krewer
    Why Are There Seeds In My Banana? A Look at Ornamental Bananas Esendugue Greg Fonsah, Richard Wallace, and Gerard Krewer In many parts of the world bananas are a staple food, while in other regions they are a highly valued ornamental plant. Bananas are the fourth most important food crop in the world, and they are also used in many other ways—every part of the plant has value. In addition to the standard dessert bananas, there is another group of species in the banana ge- nus that are much less known in the United States but offer some wonderful options as landscape plants. This group of banana species is known as ornamental bananas. This paper sheds some light on ornamental banana cultivars that provide a tropical atmosphere to gardens in the Southeast region of the United States. Bananas (Musa spp) are the fourth most important group include yellow, purple, pink, red, white, and food crop in the world (Fonsah, Krewer, and Rieger multicolored.

  • 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.

  • Musa Acuminata (Banana, Edible Banana) Size/Shape
    musa acuminata (Banana, Edible Banana) Banana is short lived herbaceous plants with large rhizomes. Banana recognized by its large, fleshy, upright stalks topped with soft, smooth, arching leaves. Ranging from 1 m for the dwarf species to over 5-6 m for the largest types, Banana ''trees'' are guaranteed to lend a tropical flavor to any landscape setting. The broad, tender leaves are easily torn by winds and plants should be located in a sheltered area to prevent this. The unusual reddish-purple flowers are followed by clusters of upwardly-pointing green fruit, maturing to a beautiful yellow. After the fruit appears the plant dies back. If we cut the trunk back until the ground new growth will appear. Growing best on fertile, moist soil, Bananas will thrive in full sun or partial shade and should be protected from both wind and cold. Plants respond well to regular fertilization. Many different species of Banana are available. Some ornamental types are grown for foliage or flowers. The best usages for Banana as a specimens or container plant.
