上海蚕豆地方资源鉴定评价与遗传多样性分析
Evaluation and genetic diversity analysis of Shanghai faba bean germplasm resources
摘要
Abstract
To understand the genetic diversity of Shanghai faba bean germplasm resources,the main agronomic traits of 43 resources from Shanghai under the third national survey and collection action on crop germplasm resources were analyzed.The results showed that a higher genetic diversity in these faba beans.The variable coefficient of 13 quantitative traits were 5.7％-37.5％.The correlation analysis reviewed that the yield as well as pod number was positively correlated with seed number per plant(P＜0.01).The principal component analysis showed that 5 principal components including yield,seed and pod traits with a cumulative contribution rate of 75.560％.Two main categories were divided for 43 resources by cluster analysis.Group Ⅰ and Ⅱ contained 32 and 11 resources,respectively.Two subpopulations were divided in group Ⅰ.Group Ⅰ-1 represented larger seed,higher yield per plant,and light brown seed.Group Ⅰ-2 represented large seed.The accessions from group Ⅰcould be used as breeding materials for new large-seed varieties.Group Ⅱ represented small seed and more pods per plant,which could be used as breeding materials for new small-seed and more pods varieties.This study can provide the foundation of materials for faba bean breed improvement.关键词
