豇豆新品种“桂豇一号”选育及品种比较试验研究

Comparative Test on the Variety and Breeding of New Cowpea Variety Guijiang 1

[目的]选育出适合广西地区栽培及市场需求的优质、高产、抗病的豇豆新品种,促进广西地区豇豆产业的持续发展。[方法]采用常规系谱选择法选育出豇豆新品种,暂定名为"桂豇一号"豆角,将其与广西区内主栽豇豆品种进行田间经济性状、产量及抗病性比较试验。[结果]"桂豇一号"的商品荚率、荚长、荚厚、单荚重均表现最好,早、晚造产量分别为35 713.5和34 185.0 kg/hm2,其产量最高,且与农家自留种早、晚造产量之间的差异均达显著性水平,同时其还具有较强的抗病性。[结论]"桂豇一号"具有高产、优质、双荚率高、抗病力强等特点,适宜在广西区大力推广种植。

[Objective] To breed high-quality, high-yield, disease-resistant cowpea variety suitable for cultivation in Guangxi Area, and to promote the sustainable development of cowpea industry in China.[Method] Conventional pedigree selection method was used to breed the new variety of cowpea, tentatively named Guijiang 1.Comparative test was carried out on the field economic traits, yield and disease resist-ance between Guijiang 1 and main cultivated variety in Guangxi.[ Result] The commodity pod rate, pod length, pod thickness, single pod weight of Guijiang 1 all showed the best performance.The first season and second season yields were 35 713.5 and 34 185.0 kg/hm^2 , respec-tively.Guijiang 1 had the highest yield, and showed significant differences with the yield of farmers retained varieties.At the same time, Gui-jiang 1 had strong disease resistance.[ Conclusion] Guijiang 1 has the characteristics of high yield, high quality, high dual-pod rate, and strong disease resistance, which is suitable to be widely planted in Guangxi.
