以晋旱125×(昔野×501)杂交组合的亲本及后代群体为试验材料,对其株高、主茎节数、茎粗、结荚高度和有效分枝数5个株型性状和株质量、主茎荚数、分枝荚数、一粒荚数、二粒荚数、三粒荚数、四粒荚数、瘪荚数、总荚数、虫食数和百粒质量11个产量性状与单株产量间的关系进行相关性和主成分分析。结果表明,株型性状和产量性状与单株产量的相关性从大到小为总荚数、株质量、二粒荚数、主茎荚数、三粒荚数、分枝荚数、茎粗、主茎节数、一粒荚数、结荚高度、株高、百粒质量、虫食数、有效分枝数、四粒荚数和瘪荚数。17个性状中,可以提取出5个主成分,其中,荚型因子影响最大,其次是株型因子。
The parents and progenies of 125 × crosses of wild × × × × × × × were used as experimental materials. Five plant type traits and strains, including plant height, number of main stems, stem diameter, pod height and effective number of branches, Quality, number of main stem pods, number of pods, number of pods, number of pods, number of pods, number of pods, number of pods, number of pods, number of pods, number of insects and quality of 100 grains Correlation and principal component analysis were used to analyze the relationship between traits and plant yield. The results showed that the correlation between the plant type traits and the yield traits and the yield per plant was as follows: total pod number, plant mass, two pods, main pods, three pods, branch pods, , The number of main stems, a pod number, pod height, plant height, the quality of one hundred, the number of insect food, the number of effective branches, four pods and deflated pods. Among the 17 traits, five principal components were extracted. Among them, the pod factor had the greatest impact, followed by the plant type factor.
