The study was carried out to determine the genetic variability and correlation of seed cotton yield with various yield contributing traits under organic conditions. The eight breeding lines and four commercial varieties (checks) were evaluated in a RCB design with three replications for two years (2010-11 &2012-13) at Institute of Organic Farming, UAS, Dharwad. Pooled analysis of variance revealed significant differences among genotypes, years and their interaction. The genotypes revealed significant differences (p>0.01) for characters like plant height, no. of monopodia and sympodia, mean boll weight, seed cotton yield per plant, SCY/ha and Micronaire. Highest seed cotton yield over two years was recorded by CPD-1012 (1338kg/ha) which is also recorded higher plant height, number monopodia and number of bolls. However, Abadhita recorded higher seed cotton yield (1326.3kg/ha), number of bolls, uniformity ratio, micronaire and mean boll weight, with lower 2.5% span length. The characters like number of monopodia and sympodia, number of bolls per plant, chlorophyll content, mean boll weight and seed cotton yield per hectare exhibited moderate PCV along with moderate heritability and genetic advance as percent of mean. The genotypic and phenotypic associations of seed cotton yield were positive and highly significant with number of monopodia and sympodia, number of bolls per plant, LAI, SPAD and mean boll weight indicating that selection based on these traits would bring about improvement in seed cotton yield.
