Abstract

The present research was carried out to estimate the G×E interaction and stability  of  four CMS lines, nine testers and 39 hybrids over three locations viz., Oilseed Research Unit, Dr. PDKV, Akola, Regional Research Centre, Amravati, and Agriculture Research Station, Yavatmal during the kharif-2019 season in randomized block design with three replication using Eberhart and Russell's model. Pooled analysis of variance due to genotype and environments showed highly significant for all the traits revealing the existence of variability among genotypes and environments. G×E interaction was significant for all the traits except 100 seed weight indicating the differential response of genotype to different environments. Environmental indices revealed that Akola was the most favourable location for the expression of sunflower crop. The three hybrids viz., PDKVSH - 952, LSFH - 171 and AKSF -10-1-1A × Gp6961 were found to be stable for seed yield while four hybrids i.e., CMS - 302 A×AK- 1R, DRSH - 1, CMS - 302 A×Gp6961 and CMS - 302 A×PKV - 103R were found suitable for favourable environments. The current work may be helpful for determining stable genotypes in sunflower for diferent locations.
