摘要
为培育高产苜蓿新品种选择亲本提供依据和种质材料,对87个苜蓿品种草产量、株高、干鲜比、叶茎比、叶面积、分枝数、茎节长、茎节数、单位长度茎节数等农艺性状指标在河南三地进行测定评价,并统计分析。结果表明:株高、茎节长与草产量显著正相关且相关系数处在第一、二位,茎节长与株高显著正相关,干鲜比、单位长度茎节数与株高显著负相关;选出综合表现优良且适宜河南示范推广的WL919、天马、巨能601、克劳迪、巨能995、游客等苜蓿品种,得到高产、株高高、茎节长、分枝数多、干鲜比高、叶茎比高、茎节数多等的优良品种。
To provide a basis and germplasm materials for the breeding of high-yielding alfalfa cultivars,the agronomic traits of 87 alfalfa varieties-including herbage yield,plant height,dry-to-fresh weight ratio,leaf-stem ratio,leaf area,number of branches,internode length,internode number,and number of internodes per unit length-were evaluated and analyzed across three locations in Henan Province.The results indicated that plant height and internode length showed the most significant positive correlations with herbage yield,with correlation coefficients ranking first and second,respectively.Internode length was also significantly positively correlated with plant height.Conversely,dry-to-fresh weight ratio and the number of internodes per unit length were significantly negatively correlated with plant height.Based on comprehensive performance,varieties such as WL919,Tianma,Juneng 601,Claudi,Juneng 995,and Youke were selected as suitable for demonstration and promotion in Henan,demonstrating high yield,tall stature,long internodes,numerous branches,high dry-to-fresh weight ratio,high leaf-stem ratio,and many internodes.
