摘要
以3份嘉定白蚕豆新品种(系)及对照品种(系)(本地蚕豆、三白豆、‘陵西一寸’)为试验材料,对6个蚕豆品种(系)的生长势、主要经济性状及产量等进行比较,并运用灰色关联度分析法对其进行综合评价,以期为上海及气候相似地区的蚕豆育种和生产提供参考。结果表明:新品系12-3-H产量最高,比本地蚕豆(CK_(1))增产27.92%,比三白豆(CK_(2))增产11.28%,比‘陵西一寸’(CK_(3))增产33.94%。参试品种(系)的等权关联度和加权关联度均在0.65以上,说明参试品种(系)的关联度均较强,综合性状表现优良。基于等权关联度、加权关联度和小区产量对6个蚕豆品种(系)进行排名,显示品系12-3-H的关联度和产量排名分别为第2名和第1名。聚类分析将试验材料分为3个类群,第一类群种质分枝性强、结荚较多,第二类群种质粒多、荚多且高产,第三类群种质粒大。在选育蚕豆优良新品种时,应重点考虑单株荚质量、籽粒大小以及结荚性对产量的影响,同时要兼顾株高、分枝数等性状。品系12-3-H的等权关联度、加权关联度以及产量均表现优异,具有在上海及气候相似地区进行大面积推广种植的潜力。
In this study,three new varieties(lines)of Jiading white broad bean and the control(local broad bean,Sanbaidou and‘Lingxiyicun’)were used as experimental materials.Comparative experiments were conducted on the growth potential,main economic traits,and yield of six broad bean varieties(lines).Grey correlation analysis was used to comprehensively evaluate them,in order to provide reference for broad bean breeding and production in Shanghai and areas with similar climate.The results showed that the yield of new line 12‑3‑H was the highest,which was 27.92%higher than that of local broad bean(CK_(1)),11.28%higher than that of Sanbaidou(CK_(2)),and 33.94%higher than that of‘Lingxiyicun’(CK_(3)).The equal weight correlation degree and weighted correlation degree of the tested varieties(lines)were all above 0.65,indicating that the correlation degree of the tested varieties(lines)was strong and the comprehensive traits were excellent.Based on the equal weight correlation degree,weighted correlation degree and plot yield,six broad bean varieties(lines)were ranked.The correlation degree and yield of 12‑3‑H were ranked second and first,respectively.The test materials were divided into three groups by cluster analysis.The first group belonged to the germplasm with strong branching and more pods,the second group belonged to the germplasm with more multi‑seed pods and high yield,and the third group belonged to the germplasm with large pods.In the breeding of new varieties of broad bean,the effects of pod weight per plant,grain size and podding on yield should be considered,and the traits such as plant height and branch number should be taken into account.The equal weight correlation degree,weighted correlation degree and yield of 12‑3‑H were excellent,and it had the potential to be widely planted in Shanghai and areas with similar climate.
