内蒙古栽培大豆与野生大豆杂交后代18个株系农艺性状与产量的相关性及综合评价
Agronomic characteristics of hybrids from wild soybean and cultivated soybean in Inner Mongolia and their correlation with seed yield
摘要
Abstract
The correlation analysis of yield of progeny lines derived from cultivated soybean × wild soybean and their agronomic characteristics were performed to assess these lines and their agronomic characteristics affecting soybean yield.20 agronomic characteristics of 18 stable progeny lines were analyzed by factor analysis.The quantitative trait analysis of plant and seed of progeny lines showed that the agronomic characteristics of each line had significant difference.5 common factors were extracted by factor analysis,and the cumulative variance contribution rate was 73.611％.This result indicated these 5 common factors could primely reflect the information of these 20 traits,and the factor analysis was reliable for assessing the effect of agronomic characteristics on yield.Integrated assessment of each line and its agronomic characteristics was used to screen out 5 lines of promotional value.The results showed that agronomic characteristics such as three-pod number,first-class branch,stem weight and effective branching could be used for evaluating soybean yield.5 lines including 15,3-2-2,60Co 600,18-2 and 8-1-2 were selected for further promotion,which could help to utilize and protect wild soybean resources.关键词
