Comprehensive evaluation of promising Gossypium hirsutum L. genotypes under rainfed conditions and their path of productivity analysis



The present study involves evaluation of 38 genotypes of G. hirsutum for productivity and fibre propertiesduring kharif seasons of 2014-15 and 2015-16, at Agricultural Research Station, Dharwad Farm. The analysis of varianceand pooled analysis revealed significant differences among the genotypes for all the traits studied across two years. Overtwo years of testing, the genotypes G h AM-46, MAP-20-4 and G h AM-9 were found to be high yielding and also hadother desirable characters. Genotype G h AM-46 had high seed cotton yield and lint yield. G h AM-9 had desirablecharacter of high boll weight while, MAP-20-4 had higher boll number. G h AM-9 can be considered an excellent genotypeas it had relatively high yields coupled with good fibre length and fibre strength. The path of productivity analysis indicatedexistence of genetic diversity among potential genotypes and desirable deviations with respect to traits contributing to highproductivity.
