花生产量与主要农艺性状、品质性状的灰色关联度分析
Analysis of grey correlation degree between peanut yield and major agronomic and quality traits
摘要
Abstract
[Objective]To screen for high-yield and high-quality new peanut varieties suitable for planting in southern Xinjiang.[Methods]With 19 newly introduced Huayu series of peanut varieties as the test materials,major agronomic trait were investigated,and yield traits,quality traits were determined.Variability,correlation,gray correlation degree and cluster analysis were performed for all tested varieties.[Results]The main stem height,lateral branch length,number of pod branch,100-pod weight and 100-kernel weight were significantly positively correlated with the yield of the tested varieties(P＜0.05),the correlation coefficients were 0.518,0.509,0.508,0.646 and 0.649,respectively.The top 5 rank of grey correlation degree were main stem height＞lateral branch length＞100-pod weight＞number of pod branch＞100-kernel weight.In the cluster analysis,the overall traits of the class I were better,the main stem height,lateral branch length,total number of branch,number of pod branch,100-pod weight,100-kernel weight,single plant productivity and yield were higher than those of the other three classes.[Conclusion]The main stem height,lateral branch length,100-pod weight,number of pod branch,100-kernel weight have a great influence on peanut yield,and can be used as reference indicators for peanut introduction screening and high-yield breeding.关键词
