GENETIC VARIABILITY, CORRELATION AND PATH ANALYSIS IN YIELD AND YIELD COMPONENTS IN CHICKPEA (Cicer arietinum L.) GENOTYPES UNDER LATE SOWN CONDITION
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 54
Abstract
Thirty eight chickpea varieties were studied to find out genetic variability, genetic association and path coefficient analysis for grain yield and its attributing characters. Both genotypic and phenotypic variances were highly significant for all the traits with little higher phenotypic coefficient of variation. The low differences between the phenotypic and genotypic coefficients of variations indicated low environmental influences on the expression of these characters. High heritability coupled with high genetic advance were obtained with harvest index, seeds per pod, total number of pods per plant, seed yield per plant, days to maturity. Genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients in most of the traits. Harvest index, 100-seed weight, seeds per pod, number of effective pods per plant, total number of pods per plant, number of primary branches per plant per plant and plant height were the most important characters, which possessed positive association with seed yield per plant. Path coefficient analysis revealed that among the different yield contributing characters harvest index, 100-seed weight, seeds per pod, total number of pods per plant, number of secondary branches per plant, plant height, days to maturity and days to 50% flowering influenced seed yield per plant directly. Thus, selection for yield in chickpea through these characters would be effective.
