13个河南白芝麻品种单株产量与相关农艺性状的灰色关联分析及综合评价

Comprehensive Evaluation of Agronomic Traits and Yield per Plant of 13 Sesame Accessions in He'nan by Grey Correlation Analysis

为探讨芝麻品种单株产量和相关农艺性状之间的关联程度,采用灰色关联分析法对13个河南白芝麻品种农艺性状进行分析,并引入参考品种构成灰色系统进行综合评价。结果表明,7个其他农艺性状与单株产量关联度排序为:株蒴数>蒴粒数>果轴长>株高>千粒重>腿位>黄稍尖长;芝麻品种的加权关联度前三位的是郑芝05 N 05、周10 J 5和漯06-8。

In order to explore the degree of correlation between yield per plant and related agronomic traits of sesame varieties,grey correlation analysis was used to analyze the agronomic traits of 13 He'nan white sesame varieties,and the reference varieties were introduced to form a grey system for comprehensive evaluation.The results showed that the correlation degree of seven other agronomic traits with yield per plant was as follows from big to small:number of capsules,number of capsules,fruit axis length,plant height,1000-seed weight,leg position,yellow tip length.Zhezhi 05 N 05,Zhou 10 J 5 and Luo 06-8 were the top three types of weighted correlation degree of sesame varieties.
