Genetic variability, heritability and genetic advance in f3 generation of chickpea (Cicer arietinum L.)

Abstract

Nineteen F3s + one check variety of chickpea were grown at the Pulses Research Station, Junagadh Agricultural University, Junagadh during rabi 2016-17 to estimate variability, heritability and genetic advance for 11 traits (days to 50% flowering, days to maturity, plant height (cm), number of branches per plant, number of pods per plant, first pod bearing node (cm), number of seeds per pod, 100-seed weight (g), seed yield per plant (g), biological yield per plant (g) and harvest index%). Significant variation among the F3s was evident for genetic variability among the traits studied. A wide range of variation was observed for harvest index, number of pods per plant, plant height and days to maturity. The high genotypic coefficients of variation were observed for number of pods per plant, harvest index and biological yield per plant. High estimates of heritability were registered by most of the characters but number of pods per plant and number of branches per plant had moderate estimates. The high estimates of phenotypic and genotypic coefficient variation, heritability and genetic advance expressed as percentage of mean were observed for number of pods per plant, harvest index, biological yield per plant and 100-seed weight.
