摘要: 【目的】筛选适宜新疆南疆地区种植的高产、优质花生新品种。【方法】以引进的19个花育系列花生品种为供试材料,进行主要农艺性状调查和产量性状、品质性状测定,并对所有参试品种进行变异性、相关性、灰色关联度以及聚类分析。【结果】参试花生品种的主茎高、侧枝长、结果枝数、百果重和百仁重与产量呈显著正相关关系(P<0.05),相关系数分别为0.518、0.509、0.508、0.646、0.649;灰色关联度排序前5位为主茎高>侧枝长>百果重>结果枝数>百仁重。聚类分析综合性状表现较好的为第I类,其中主茎高、侧枝长、总分枝数、结果枝数、百果重、百仁重、单株生产力和产量均高于其他3类。【结论】主茎高、侧枝长、百果重、结果枝数和百仁重对花生产量的影响较大,可以作为花生引种筛选和高产育种的参考指标。

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.
