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.

A total of one hundred and sixty germplasm accessions of Gossypium barbadense were evaluated for sixteen traits to assess their per se performance, variability, heritability, genetic advance, correlation and path analysis. The analysis of variance had shown significant differences between the genotypes for all the traits indicating the presence of sufficient variability in the experimental material.

Studies on the genetic basis for resistance to jassid (Amrasca biguttula biguttula) was done in F2 segregating generation of one promising cross of interspecific cotton (Gossypium hirsutum L. X Gossypium barbadense L.) in the year 2015-16. The cross FQT-37 X SB-YF-425 segregated in the ratio of 13:3 for susceptibility and resistant. In the case of resistant type, all the plants were in grade II, implying moderate resistance. This gene action is called as inhibitory gene action.

Line × tester analysis was undertaken to assess the magnitude of heterosis in 32 interspecific heterotic group hybrids (G. hirsutum x G. barbadense) of cotton for seed cotton yield and its components developed by crossing eight elite hirsutum lines with four elite barbadense testers during Kharif 2010-11 at Main Agricultural Research Station, Dharwad.

The 1329 F2, 174 B1 and 191 B2 plants were evaluated along with parents (Suvin and BCS 23-18-7) and its F1 for seed cotton yield and its component traits and fibre quality traits. Top 20 transgressive segregants were selected for seed cotton yield from all three segregation generations (F2, B1 and B2), recorded 104.02 to 169.46 per cent higher seed cotton yield than best parent BCS 23-18-7 (116.90 g/plant). Six transgressive segregants recorded 5 per cent early flowering (< 65 days) with a minimum of 50 per cent yield advantage (> 177 g) over BCS 23-18-7.

Fifty cotton genotypes were investigated for variability and genetic divergence regarding yield related attributes, seed cotton yield and fibre quality traits using principle component analysis. Eleven traits viz., days to flowering, plant height (cm), no of sympodia/plant, no of bolls, boll weight (g/plant), seed cotton yield (kg/ha), Micronnaire value, % Span length, Uniformity ratio, Bundle strength (g/tex) and Elongation ratio were recorded for the germplasm accessions. Maximum variation of about 17.

Genetic diversity analysis was conducted at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during Kharif, 2017. In this study, 35 genotypes were evaluated for 11 yield and yield attributing traits and grouped into four clusters through Mahalanobis D2 statistic. Cluster I was the biggest with 23 genotypes followed by cluster II, III and IV. Among eleven characters studied, seed cotton yield (25.38 %) and days to 50 per cent flowering (22.86 %), contributed high for divergence while other characters like boll weight (0.34 %), number of sympodia per plant (0.
