四棱豆优良品种的引种和良种选育研究

Study on Introduction and the Selective Improved Variety of Winged bean [Psophocarpus tetragonolobus (L.) DC]

1998～ 1999年 ,在四川南充市对 15份四棱豆材料进行了引种和良种选育试验。选出了适合四川南充地区栽培的 4个优良品种 ,其中 96 - 13具早熟、高产、抗病特性 ;K0 0 0 9和K0 0 10具高产、抗病特性 ;96 - 14 - 1具矮生直立、抗病特性。

From 1998 through 1999, we conducted experiments on the introduction and the selective improved variety in Nanchong of Sichuan province to compare 15 Winged bean varieties. Four improved varieties were selected which are all fit for growing under the climatic condition in the Nanchong area , the variety 96-13 has early-maturing, high-yielding and disease resistance characters , the K0009 and K0010 have high-yielding and disease resistance characters , the 96-14-1 has low-growing, erection and disease resistance characters.
