Abstract:

The present study was conducted on genetic variability, correlation coefficient analysis for seed cotton yield and its component traits in 18 brown coloured cotton genotypes collected from CICR, Nagpur, which was carried out during kharif2018 at the Main Agricultural Research Station, UAS, Raichur, Karnataka. Observations on traits viz., plant height at harvest, number of sympodia, number of monopodia, sympodial length at ground level, sympodial length at 50% plant height, number of bolls per plant, lint index, boll weight, internodal distance, seed index, seed cotton yield per plant, ginning out turn, fibre length, fibre strength and micronaire were recorded. The results showed that highest GCV for number of monopoodia per plant and sympodial length at 50% plant height. Highest heritability was observed for number of sympodia, plant height, fibre length ginning out turn and seed index. Plant height at harvest, number of monopodia per plant, number of sympodia per plant, sympodial length at ground level, intermodal distance were positively correlated with seed cotton yield and the traits viz., seed index and fibre length exhibited negative correlation.
