Abstract:

The success of most crop improvement programs depends upon the genetic variability and heritability of desirable traits. The genetic variability and heritability study was carried out in F2 population of Suvin X BCS 23-18-7 cross, at College of Agriculture, UAS Darwad during Kharif 2016-17. The highest range of variation was observed in F2 population for seed cotton yield per plant (5.5 g - 259 g) followed by plant height (30 -205 cm) and lint yield per plant (2 - 89.5 g) while lint index (1.87 - 8.68) recorded lowest range of variation. Respectively PCV and GCV per cent were recorded higher (> 20 %) for number of monopodia per plant (46.08 and 26.09), number of sympodia per plant (27.86 and 21.99), boll weight (25.69 and 22.99) and seed cotton yield (32.80 and 20.51) while moderate (10 - 20 %) for plant height (17.56 and 14.16) and lint yield (13.09 and 11.43) but high PCV and moderate GCV observed for number of bolls per plant (25.40 and 14.19). Higher heritability (> 60 %) was observed for plant height, number of sympodia per plant, seed index, ginning outturn, lint index, boll weight and seed cotton yield per plant. Whereas, days to first flowering, number of monopodia per plant, number of bolls per plant and seed cotton yield per plant were recorded moderate (30 - 60 %) heritability. Similarly, Genetic advance over mean high (> 20 %) for plant height, number of monopodia per plant, number of sympodia per plant, lint yield per plant, lint index, boll weight and seed cotton yield per plant while moderate (10 - 20%) for number of bolls per plant, seed index and ginning outturn. But, only days to first flowering (3.35) recorded lower GAM. Traits which showing high heritability coupled with moderate to high GAM (plant height, number of sympodia per plant, seed index, ginning outturn, lint index, boll weight and seed cotton yield per plant), supports for recovery of desirable lines through selection.
