Abstract:

Cotton is a long duration crop and grown over a wide range of environments. It is, therefore necessary to evaluate cotton genotypes in different environments to know its stability in varying environmental conditions. The knowledge of kind and magnitude of G x E interaction has become essential to the plant breeder in taking the decisions concerning breeding methods, selection programmes and their testing procedures in crop plants. Stability in yield is a major consideration in breeding of rainfed cotton which is highly influenced by erratic and uncertain rainfall conditions. Development of stable genotypes with high yield potential under rainfed condition is need of the day to meet the growing domestic demands of medium and superior medium staple cotton. Fifty six crosses with fifteen parents and four checks viz., PKVDH1, PKV Suvarna, NACH 12 and PA 255 were grown in Randomized Block Design with two replications. The experiment was conducted under rainfed condition at three locations viz., Cotton Research Station, MB Farm, Parbhani (L1), Cotton Research Station, Nanded (L2), and Agricultural Research Station, Badnapur (L3) during kharif, 2016.The observations are recorded days to 50 % flowering, days to 50 % boll bursting, plant height, no. of sympodia per plant, no. of bolls per plant, boll weight, seed cotton yield per plant, seed index, lint index, harvest index and days to maturity. This experiment has resulted in identification of four parents i.e. PA 809, PA 785, HD 514, and PA 832 which were found to be stable and responsive to the low yielding environment which can be used as parents for improving yield stability of the cotton genotypes. The results showed that the stable crosses for the seed cotton yield per plant were PAIG 346 x JLA 794, PAIG 346 x DWDa 1402, PA 785 x CNA 449, PAIG 346 x CNA 449, PAIG 346 x HD 514 and PA 801 x HD 514 which have also responded well to favourable environments.
