Selection Of Banana Breeding New Lines And Production Test

Along with the development of the banana industry, banana cultivation is increasing. Banana producers New Line on the quantity, quality, drought resistance, disease resistance, wind resistance, Traits such as growth period of growing demand, but the current Hainan banana cultivars single, Brazil banana cultivation of bananas covering a total area of the province of 80%. "8818", "Brazil banana" in the long process of cultivation, varieties have been degraded. This study from 2001 to use breeding methods, from the production area on the promotion of large groups of varieties to yield, quality, drought resistance, disease resistance, wind resistance and reproductive traits period goals to make choices, 2004 elected a fine line, in 2005 and 2006 for pilot production and promotion. The main findings are as follows :(1) Mixing the method chosen from the production of varieties promotion groups were selected from a fine lines. The strains of higher yield, good quality and strong resistance, a shorter growing period. Its characteristics are as follows : Biological characteristics The lines for stem types, The average height of 231cm , stem diameter cylindrical 70.2cm; ear, the fruit section of uniform, fruit slender means, up to 20cm above, the fruit index 130 per panicle; 10 per panicle fruit of 6-8 10, the average seven 10; Single Ear Weight 24.4kg; field planting early squaring 130 days to 270 days after the beginning of harvest, growth period of about 310 days; vigorous growth, good resistance.Commercialâ‘ Good appearance, deeply consumers. Ear performance in nearly cylindrical-shaped, fruit size 10 uniform, slender fruit means uniform; Harvest, the color yellow, and green fruit, good gloss; Fruit ripening consequences golden color, the color uniform .â‘¡Taste sweet flavor of Luzhou, in line with the Brazilian bananas.â‘¢uniform size fruit to packing and storing. Production potentialâ‘ High efficiency. First, high yield, up to 3800kg per mu more than 15% increase over Brazil. Second, the low cost of planting, because of the growth cycle in Brazil less than 40-45 days, which means fruit long and evenly, not spraying fruit agent, thereby reducing investment by more than 20%.â‘¡Resistance good. Brazil than high temperature and drought; Right conditions require less water and fertilizer, above average fertility conditions were able to achieve high and stable yields; wind-resistance and Brazil quite.(2) Through many years of research and practice, a new line Tissue Culture technology, Breeding techniques and farm management techniques. New Line Tissue Culture will be 20 days following the meeting on behalf of a value-added, the value could reach 2.0-3.0%; Algebra proliferation in general control 10 generation; Rooting transplant survival rate of 100%, 100%. Seedlings cultivated by 40-50 days to reach the standard out of garden (at 15cm high above the stem, leaf number 6 above). Planting seedlings strengthened management, general harvest about 310 days end, the yield 3800kg/ acres.
