Association Studies in Fenugreek (Trigonella foenum-graecum L.) for Yield and its Attributing Trait

Fenugreek (Trigonella foenum-graecum L.) such an important seed spice crop having medicinal, industrial and economical importance in India. To overcome the demand of fenugreek, breeding for yield improvement is a crucial step. For increment in seed yield which is a quantitative trait having influence of multiple genes as well as contributing of many traits, taking this reason it is necessary to find the association of seed yield with its contributing traits. So, an experiment was conducted with 38 genotypes in Randomized Block Design with three replications at instructional farm, college of agriculture, Jodhpur (Rajasthan) during Rabi 2024-25. Correlation coefficient shows that trait seed yield per plant having positive and significant correlation with number of pods per plant, pod length, number of seeds per pod, 1000-seed weight, biological yield per plant and harvest index. The results of path analysis revealed that highest positive direct effect on seed yield per plant was exerted by harvest index, while days to 50% flowering exerted negative direct effect maximum indirect effect was exerted by biological yield per plant on seed yield per plant through number of pods per plant. The experimental results conclude that selection of these traits may bring simultaneous improvement in seed yield in fenugreek.
