| 摘 要： | 桂豇2号是以广西南宁市农家品种甜肉豆角的优选单株M133-6为母本,以广东阳江农家品种黑籽豆角的优选单株F12-5为父本进行杂交,经系统选育而成的中熟豇豆新品种。主侧蔓均可结荚,始花节位为第4~6节,每花序可结荚2~3条,商品荚浅绿色,平均荚长55 cm,单荚质量约30 g,豆荚肉厚,味甜。春季播种至始收约55 d(天),夏秋季播种至始收约50 d(天),全生育期90~110 d(天),产量1 900~2 000 kg·(667 m~2)~(-1)。田间对锈病、白粉病、煤霉病的抗性均优于广西当地豇豆主栽品种华珍豆角。适宜华南地区春秋季种植。

| Abstract: | ‘Guijiang No.2’ is a new mid-maturing cowpea variety developed by crossing‘ M133-6’ as female parent and‘ F12-5’ as male parent through systematic selection．Its pods can bear on both main and lateral
vines．The first flower sets on the 4-6th node．Each inflorescence could bear 2-3 pods．The commercial pod is
light green in color and average pod length is 55 cm．The single pod weight is about 30 g．Its pod pulp is fleshy
and sweet．In spring，it takes 55 days from sowing to harvest，and 50 days in autumn．The whole growing
period is 90-110 days．It can yield 28.5-30.0 t·hm-2．Its resistances to rust，powdery mildew，sooty blotch
in field are better than that of the local main cultivar‘ Huazhendoujiao’ from Guangxi Province．It is suitable for
cultivation in southern China in spring and autumn． |
