Comprehensive analysis of mosaic virus resistance in soybean varieties from Henan Province
摘要
Abstract
Soybean varieties approved in Henan Province from 2020 to 2024 were used to systematically evalu-ate the resistance of soybean germplasm resources to both the weak(SC3)and strong(SC7)strains of soybean mo-saic virus(SMV).A comprehensive analysis was conducted to examine the correlations among mosaic resistance,yield,agronomic traits,quality traits,and genetic background of soybean in regional trials.The results showed that 81 soybean germplasm resources exhibited significant variation in resistance to prevalent strains of soybean mosaic virus(SMV),following a normal distribution.Over the years,the disease index gradually declined,while resist-ance levels increased.Multi-year regional trials identified 15 germplasm lines with dual resistance to both SC3 and SC7 strains,accounting for 18.52%of the validated varieties.The coefficient variation ranged from 2.00%to 39.96%.Correlation analysis showed that there was a significant positive correlation between the seeds number and the effective pods number.The disease index of SC3 and SC7 strains was significantly positive correlation with the effective number of branches,and significantly negatively correlated with the average yield.Principal component a-nalysis revealed that the cumulative contribution rate of the four principal component factors amounted to 79.503%.Cluster analysis divided the 15 soybean materials into four groups.Group I consists of three varieties that performed better in terms of effective branch number,effective pods number,and seeds number.Group II includes three vari-eties characterized by the tallest soybean plants.Group III comprises three varieties with the shortest growth period,the largest 100-seed weight,and the highest yield.Group IV consists of six varieties exhibiting moderate plant height,100-seed weight,and number of main stem nodes.Analysis of the parental backgrounds of five double-high MSV soybean varieties('Zheng 1825','Kaidou 1311','Huadou 45','Pudou 766',and'Kedou 42')indi-cates that choosing parents with differences in geographic latitude and superior comprehensive traits facilitates the selection of excellent hybrid varieties.关键词
