All these varie- ties call for the genetic identification and characterization of their interrelations on account of their regional socio- economic significance and their potential for banana breeding strategies. • Methods An extensive sampling of all traditional bananas in East Africa and near Indian Ocean islands was genotyped with simple sequence repeat (SSR) markers, with particular emphasis on the diploid forms and on the bananas of the Indian Ocean islands, which remain poorly characterized.

  • Banana Growing in the Florida Home Landscape1 Jonathan H
    HS10 Banana Growing in the Florida Home Landscape1 Jonathan H. Crane and Carlos F. Balerdi2 Scientific name: Musa acuminata and Musa balbisiana per plant than sweet bananas. The groups differ in whether the male parts of the inflorescence are persistent or absent. Common names for banana: English—banana, plantain; Spanish—banano, platano, guineo, cambur History and Distribution Common names for plantain: English—plantain, horse The banana and plantain are native to southeast Asia, banana; Spanish—platano where they have been cultivated for thousands of years. Bananas are believed to have been introduced to Africa in Family: Musaceae prehistoric times. Recent evidence suggests bananas were introduced into the New World (Ecuador) by southeast Relatives of banana within the Order Zingiberales: Asians around 200 BCE, and more recently by Portuguese Numerous ornamental plants including traveler’s palm, and Spanish explorers in the early 16th century. The bird-of-paradise, heliconia, and ginger. Portuguese introduced bananas into the Canary Islands and the Spanish to the Island of Hispaniola during the 1500s. Introduction Susceptibility to frost keeps the banana from spreading Bananas are vigorously growing, monocotyledonous beyond the tropics and the warm subtropics. However, herbaceous plants. There are two species of banana, Musa bananas are grown commercially in a number of subtropi- acuminata and M. balbisiana, and most banana cultivars cal areas such as Australia, Morocco, South Africa, Egypt, are hybrids of these species. Banana cultivars vary greatly Israel, the Canary Islands, and south Florida. In some areas, in plant and fruit size, plant morphology, fruit quality, and bananas are grown inside plastic or glass covered structures.

  • Banana Production Ual
    i t Uganda 01.14524 r- 1 f - - BANANA PRODUCTION UAL A guide to successful banana production in Uganda. - I BANANA PRODUCTION MANUAL: A guide to successful banana production in I I Uganda. Editors: Wilberforce K. Tushemerehe Imelda N. Kashaija William Tinzaara Cadme Nankinga Stephen New Fit edition 2001 The banana is one of the most important food security and cash crops in Uganda. Areas of the country where banana is the main staple experience less famine. This is because the crop's all-year-round hiting habit coupled with high yield ensures continuous supply of food. For a long time, the crop was believed to be hardy and able to continue growing well in Uganda as long as the nutrient levels in the plantations were adequate. However, the crop has been losing ground because of a complex of problems including soil fertility decline, pest/disease build-up and socio-economic problems. In recent years, drastic yield decline in the traditional banana growing areas of central Uganda has led to a replacement of bananas with annual crops. Annual crops require more elaborate phasing or storage in order to have food all the year round. Many farmers in the areas where bananas have lost sustainability appear unable to cope with the storage requirements of annual crops hence they are facing frequent food shortage crises. Displacement of bananas in farming systems poses a serious threat to food security, the environment and general welfare of the people in the affected area. In the past, banana was a highly sustainable crop in Uganda, with long plantation life and stable yields.

  • Medicinal and Nutritional Importance of Banana

Ltd, NashiK, Maharashtra, India *Corresponding Author: Chandrashekhar Vasant Kothawade, Agri Search (I) Pvt. Ltd, NashiK, Maharashtra, India. Received: August 14, 2018; Published: April 15, 2019 Abstract The Cavendish subgroup is the most widely grown group of bananas since it includes the cultivars that dominate the international trade in bananas (e.g. Grande Naine, Williams and Valery) and as such have set the standards in terms of taste, yield and post-harvest characteristics expected of an export banana. They are also increasingly grown for domestic markets. In 2010, Cavendish cultivars accounted for about 40% of the global production of bananas, which includes the 27% produced for domestic markets and the 14% grown for export[1]. Their domination of the international trade started in the late 1950s when they were selected to replace Gros Michel, whose susceptibility to Fusarium wilt precluded its cultivation in large commercial plantations. Although Cavendish cultivars are resistant to the race 1 strains of the fungus that causes the disease, they are susceptible to tropical race 4.

Case study Economic significance of banana varieties other than Cavendish in Uganda Part 1: Country report Part 2: Banana production in Uganda: Area information from BOAP and statistics from FAO, CIRAD and UBOS Part 3: Country factsheet Part 1. Report on economic significance of banana varieties other than Cavendish in Uganda by Deborah Karamura (Bioversity International, Uganda Office) Background The East African plateau is home to a unique banana subgroup (Musa‐AAA) known as Lugira‐Mutika (Simmonds 19662) or the East African highland bananas (EAHB) (Karamura et al. 1999). The subgroup is grown in a number of countries to the north and west of Lake Victoria, including Uganda, Kenya, Tanzania, Rwanda, Burundi and the Democratic Republic of Congo. The region is recognized as a secondary centre of diversity for the crop (the presumed primary centre being the Indo‐Malaysian region in Asia) and is one of the largest producers and consumers of bananas in the world, with Uganda producing about 60% of the region’s banana annual output. Depending on the cultivar, these bananas are consumed as a staple food (locally known as Matooke), as a beverage (banana beer, juice or banana gin), as a diversity of confectionaries (cakes, crisps, bread, solar dried figs, chips, etc) and may be roasted or fried and consumed as snack meals.

La caracterización incluyó propiedades físicas como peso, diámetro, longitud, materia seca y porcentaje de cáscara del fruto y propiedades funcionales de almidones (cur- vas de empastamiento). Las variedades Cachaco Pelipita, Fougamou, Kelong Mekintu y SH-3436-9 presentaron porcentajes de materia seca superiores al 35% lo cual indica que estas variedades serian de gran importancia para el sector de las frituras ya que al contener menos agua el proceso se agilizara incrementando el rendimiento y disminuyendo la absorción de aceite. Las variedades que presentaron mejores comportamientos frente a las propiedades de viscosidad máxima, breakdown, facilidad de cocción y consistencia fueron FHIA-23, Guineo Enano, Banano Gran Enano, Pompo Comino, lo cual indica que estas variedades tenían gran capacidad para resistir los procesos de retrogradación y la sinéresis.

  • 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.
