Estimates of Genetic Variability and Correlation Coefficient for Yield and Its Attributes in Fenugreek (Trigonella foenum-graecum L.)

Abstract

The study was conducted throughout the autumn/winter season 2021-2022 with the aim of estimating genetic variability for different characters in available Fenugreek germplasm viz: heritability in broad sense, genetic advance in per cent of mean and correlation coefficient among the characters pairs. The study's experimental material comprised 42 genotypes along with one check (Hisar Sonali). There were eleven quantitative characteristics (traits) on which observations were made. The magnitude of the phenotypic coefficient of variation (P.C.V.) was greater than the genotypic coefficient of variation (G.C.V). The greatest differences in phenotype and genotype have been found in seed yield per plant followed by (no.) number of branches per plant, harvest index, days to maturity, test weight and no number. of seed per pod. The heritability estimates for various traits ranged from 15.9 (no number. of branches per plant) to 68.3 (plant height). Genetic advance in per cent of mean ranged from 3.36 per cent (No. number of seed per pod) to 12.64 per cent (days to maturity). The phenotypic and genotypic correlation coefficients were computed among the eleven characters. The most (A very) important trait, seed yield per plant exhibited highly significant and positive phenotypic correlation with, harvest index (0.948) and test weight (0.935). While, days to 50% flowering (-0.678) was significantly and negatively correlated with seed yield per plant. These findings suggested that the current fenugreek germplasm has a great deal of promise for effective crop improvement and better yield and yield-(components) attributing traits.
