Assessment of biochemical parameters and genetic variability in chickpea (Cicerar arietinum L.) genotypes

Abstract

The present investigation was conducted to evaluate biochemical constituents and genetic variability of fifty six genotypes of chickpea at ZARS, Ganeshkhind, Pune (M.S) during rabi, 2018-19. Significant variations was observed in biochemical attributes viz., Calcium, Carbohydrates, Crude fibre, Protein, Fat, Iron, Niacin, Phosphorus, Riboflavin, Starch, Thiamine, Vitamin B-6 and Vitamin A ranging from 83.99 to 185.2 mg, 46.89 to 73.33 per cent, 1.98 to 9.28 per cent, 21.26 to 32.96 per cent, 0.11 to 1.44 per cent, 3.55 to 14.14 mg 0.68 to 2.16 mg, 348.2 to 446.87 mg, 0.16 to 0.33 mg, 26.80 to 50.08 per cent, 0.33 to 0.62 mg, 0.39 to 0.8 mg, 10.77 to 30.82 mg respectively. High estimates of heritability were observed for almost all the characters. Highest heritability was observed for riboflavin (99 per cent), followed by crude fibre, thiamine, vitamin B-6 (93 per cent), starch (92 per cent) and phosphorous (88 per cent). The lowest heritability was recorded for iron (59 per cent). The character calcium (13.69) exhibited highest magnitude of genetic advance followed by phosphorous (13.31), starch (8.03) and vitamin A (4.16). The lowest genetic advance was exhibited by riboflavin (0.05). High heritability accompanied with high genetic advance was observed for phosphorous calcium, vitamin A and crude fibre indicated that these traits were governed by additive gene action. Based on mean performance of biochemical parameters and per se performance genotypes RVSSG-54, CSJ-740, C-1830, Phule-G-171105, C-1829 and Phule-G-1115-13-16 were found promising and suggested for future breeding programme.
