不同南方大豆种质资源在贵阳地区的性状分析与评价
Character Analysis and Evaluation of Southern Spring Soybean Germplasm Resources in Guiyang Area
摘要
Abstract
In order to gain an in-depth understanding of the characteristics of soybean resources in southern China and screen and identify germplasm with excellent and special traits,311 soybean germplasm resources from Sichuan,Yunnan,Nanjing and Guizhou were used as experimental materials planted in Guiyang area,and the performance of characteristic traits,agronomic traits and quality traits of different soybean germplasm resources in Guiyang area was identified,and a comprehensive evaluation was carried out.The results showed that the characteristic traits of the tested varieties was diverse.The average coefficient of variation of traits of plant height,bottom pod height,main stem nodes number,effective nodes number,effective branches number,100-seed weight,fat content,protein content,seed weight per plant,and growth period was 21.06%,the variation coefficient of seeds weight per plant was the highest as 39.54%,and the protein content was the smallest(5.72%).The growth period of the tested varieties was 91-131 days,the protein content was 13.80%-47.72%,and the fat content was 14.19%-22.43%.The germplasms with 100-seed weight between 13-19.9 g was the most,accounting for 59.81%.The seed weight per plant was 2.48-25.44 g,and there was a large difference in seed weight per plant among different resources.Cluster analysis divided the 311 resources into three groups,among which group I had higher fat content and seed weight per plant,which could be used as high-oil and high-yield resources in southern China.In conclusion,the soybean varieties in different regions of southern China showed rich genetic diversity with Guiyang area as the planting background,and the germplasms with corresponding traits should be selected and used according to the breeding objectives of new varieties.关键词
