Studies on Path Coefficient Analysis and Correlation to Evaluate the Relationships between Yield and Its Components in Fenugreek (Trigonella foenum-graecum L.)

Abstract

The present investigation was carried out for correlation and path coefficient analysis in Fenugreek (Trigonella foenum-graecum L.) The correlation of different traits with seed yield was examined both at phenotypic and genotypic levels and the study showed that genotypic correlation coefficient values were higher than the phenotypic values. This indicated that how much of phenotypic correlation coefficient are influenced by environment. The seed yield per plant was positive and significant with biological yield per plant, test weight and number of branches per plant at genotypic and phenotypic levels. The maximum direct positive effect on seed yield per plant was observed in biological yield per plant, harvest index, days to 50 per cent flowering, number of seed per pod, number of branches per plant and number of pods per plant. In the present investigation, genotypes viz., AFG-4 and RMT-303 were superior for seed yield per plant along with other traits like biological yield, test weight and number of pods per plant. These diverse genotypes can be used in future breeding programme of fenugreek.
