四川省82份蚕豆种质资源的农艺性状鉴定与评价
Identification and Evaluation of Agronomic Traits of 82 Faba Bean Germplasm Resources in Sichuan Province
摘要
Abstract
Sichuan was one of the provinces with rich genetic diversity of faba bean resources.In this paper,82 Sichuan faba bean local germplasm resources were used as the research object.The diversity level of Sichuan faba bean local resources was identified and evaluated by genetic diversity index,variation coefficient,correlation analysis,cluster analysis and principal component analysis,and excellent germplasm resources were screened.The results showed that the genetic diversity of shape of the leaflets,color of the fresh stem,resistance of chocolate spot and resistance to ascochyta blight of faba bean germplasm resources was rich.The variation coefficient of 11 quantitative traits except pod width and growth days ranged from 11.70％to 38.39％,and the variation coefficient of seeds per pod,number of pod nodes,pods per plant and seeds per plant were larger.The correlation analysis results showed that plant height,100-seed weight,number of effective branches,number of pod nodes,pods per plant and seeds per plant were significantly or extremely significantly positively correlated with seed weight per plant.Cluster analysis clustered 82 faba bean germplasm resources into four categories,and yield-related traits of class I and V performed better.Five principal component factors with a cumulative percentage of 79.858％were extracted by principal component analysis.The effective branch number,number of pod nodes and pods per plant contributed greatly to principal component 1,which were the key agronomic traits for excellent resource evaluation.Seven germplasm resources with a weighted score of principal component factor＞1 were selected as excellent germplasm.The results of this study reflected the comprehensive performance of faba bean local germplasm resources in Sichuan,and provided data support for the protection,excavation and utilization of excellent resources.关键词
