Analysis of genetic divergence in fenugreek (Trigonella foenum-graecum L.)

Genetic divergence among 22 genotypes of fenugreek (Trigon ella foenum-graecum) was estimated for 8 quantitative characters using Mahalanobis's D' statistic and the genotypes were grouped into 6 clusters. Cluster I consisted of maximum number of 13 genotypes followed by 4 and 2 genotypes in clusters II and III, respectively. Three clusters were monogenotypic. Clustering pattern of genotypes was not related to geographical differentiation. Inter-cluster distance was highest between clusters III and VI and lowest between clusters II and VI while, intra-cluster distance was highest in cluster III. Plant height, pods plant-1, days to flowering and test weight were the major forces for divergence. &nbsp

Genetic variability, correlation and path analysis in fenugreek (Trigonella foenum-graecum L.)

Genetic variability was studied in a population of 22 genotypes of fenugreek (Trigonella foenum-graecum) at Sriniketan (West Bengal). Phenotypic and genotypic coefficients of variability were high for stem weight; moderate for plant height, branches plant-1, days to flowering, duration of flowering, shelling per cent and test weight; and low for pod length. High to moderate estimates of heritability coupled with moderate to high genetic advance were recorded for plant height, days to flowering, duration of flowering, shelling per cent and test weight indicating the predominance of additive gene action. Grain yield was positively correlated with branches plant-1 pods plant-1, pod length, seeds pod-1, pod weight, biological yield, shelling per cent and harvest index at both phenotypic and genotypic levels. Results of path analysis revealed that days to flowering, pods plant-1, pod length and seeds podol are the important characters determining seed yield in fenugreek. &nbsp
