摘要

2020 年期间，在达尔瓦德的印度植物研究所 SRRS 进行了一项调查，对七十个苜蓿（L. ）基因型进行了评估，以确定十个形态特征的特性关联，从而提高饲料产量。方差分析显示，所研究的所有性状在基因型之间都存在显著差异。相关性分析表明，干饲料产量、株高、单株分枝数在基因型和表型水平上与青饲料产量有显著的正相关。相互关系研究表明，株高、单株分枝数和干饲料产量之间存在显著的正相关。另一方面，叶茎比与青饲料产量呈负相关。路径分析结果显示，干饲料产量对青饲料产量的直接正效应最大，其次是株高和单株分枝数。研究表明，这些特征将提高选择提高饲料产量的有效性。

Association studies for yield and yield components in lucerne (Medicago sativa L.) genotypes.

An investigation was carried out to evaluate seventy lucerne ( L.) genotypes during 2020-Medicago sativarabi 21 at SRRS, IGFRI, Dharwad to determine the character association of ten morphological traits to improve the fodder yield. Analysis of variance revealed significant differences between the genotypes for all the traits studied. Correlation analysis revealed that dry fodder yield, plant height, number of branches per plant were significantly and positively associated at genotypic as well as phenotypic level with green fodder yield. Inter-correlation study revealed that a positive and significant association was found among plant height, number of branches per plant and dry fodder yield. The leaf to stem ratio, on the other hand, was negatively associated with green fodder yield. The results of path analysis revealed that dry fodder yield had the highest positive direct effect on green fodder yield, followed by plant height and number of branches per plant. While plant height and number of branches per plant contributed indirectly via dry fodder yield for green fodder yield.The study indicated that these characters would enhance the effectiveness of selection for higher fodder yield in lucerne

期刊介绍： The Society has been established with the following objectives: 1. To advance the cause of research activity in all aspects of rangelands and to encourage and promote the studies on rangeland, wasteland ecosystems and agroforestry. 2. To provide facilities for seminars and conferences to rangeland researchers, development workers and farmers and to encourage close cooperation with organizations having related aims and interests. 3. To disseminate the knowledge of scientific agriculture and technology for forage and rangeland production, improvement and management.
