摘要

该研究在印度北阿坎德邦Bageshwar的CSIR-CIMAP研究中心进行，评估了2021-22年和2022-23年期间30种葫芦巴（Trigonella foenum-graecum L.）基因型的遗传多样性。干草本每公顷重和株高的基因型（GCV）和表型（PCV）变异系数分别为47.04 %和47.43 %。遗传力范围为0.851（根长）~ 0.998（叶数），遗传进展显著。Mahalanobis D²分析将基因型分为5个聚类，PCA分析强调遗传多样性。通径分析显示残留效应极小（0.26079），证实了性状的信度。MGIDI指数鉴定出UK-17、UK-18、UK-22和UK-23基因型较优，为进一步培育适合喜马拉雅中西部地区的高产、抗病性强的胡芦巴品种提供了强大的基因型，在加强作物改良和可持续农业方面具有巨大潜力。

Quantitative assessment and character association of genetic variability in fenugreek (Trigonella foenum-graecum L.) populations from the west-central Himalayas

This study, conducted at CSIR-CIMAP Research Centre Purara, Bageshwar, Uttarakhand, India, assessed genetic diversity among 30 fenugreek (Trigonella foenum-graecum L.) genotypes during 2021–22 and 2022–23. High genotypic (GCV) and phenotypic (PCV) coefficients of variation were observed for dry herb weight per hectare (47.04 % and 47.43 %, respectively) and plant height. Heritability ranged from 0.851 (root length) to 0.998 (number of leaves), with significant genetic advance. Mahalanobis D² analysis grouped genotypes into five clusters, while PCA highlighted genetic diversity. Path analysis showed minimal residual effects (0.26079), confirming trait reliability. The MGIDI index identified genotypes UK-17, UK-18, UK-22, and UK-23 as superior, providing robust fenugreek genotypes for further exploitation in breeding high-yielding, resilient varieties adapted to the west-central Himalayas, with substantial potential to enhance crop improvement and sustainable agriculture.

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
