樹豆品種(系)雜交選育

Abstract

樹豆在臺東地區種植分布於達仁、大武、金峰、太麻里、鹿野、延平、海端等鄉之山坡地或田埂邊空地栽培，為原住民的傳統作物，亦被視為一種健康食品。目前國內地方品系均有成熟期不一致且低產之現象，造成採收及管理上的困擾，為解決上述之問題，擬以人工雜交方式於樹豆開花期進行去雄、雜交授粉，並於雜交之後代選育出高產及成熟期一致之雜交新品種，供農民種植。本場99 年以人工雜交方式獲得其雜交種子，成功率為16.5%，期望將來於雜交之後代選育出高產及成熟期一致之雜交新品種，供農民種植以增加農民收益。 Pigeon pea is planted and cultivated in the areas of Taitung County which is located in the hillside or ridge edge of the open space of Daren, Dawu, Jinfeng, Taimali, Kano, Luye, Yanping, Haiduan Township. It is a kind of traditional indigenous crops, and also is regarded as health food. Presently, since there is a maturity inconsistent and low-yielding phenomenon on the domestic local strains which would cause the troubles in harvesting and management. In order to solve the issues above, intend to adopt the methods of artificial hybridization, emasculation and pollination during the period of pigeon pea flowering. Afterwards, to select out the new species which is high production and is consistent in maturity so as to provide the new hybrid varieties for farmers to plant. The success rate of the hybrid seeds by the way of artificial hybridization is 16.5% in this field in 2000, and expecting this new varieties could offer the framers to plant in order to increase the' income in the future.
