Abstract:
The pearl millet 55 crosses along with eleven inbreds and two checks were used to study stability over four environments viz., E1: Kharif-2013, Dhule, E2: Kharif-2013, Rahuri, E3: Summer-2014, Dhule and E4: Summer-2014, Rahuri. In regards to G x E interaction studies, the mean sum of squares due to genotypes was significant for all the eleven characters studied across the environments, which indicated the presence of substantial variation in the material studied. The analysis also indicated significant variation among the environments for all the characters. The values of G x E interaction were significant for grain yield which indicated that genotypes interacted differently with environmental variations for the said characters. Among the 11 parental genotypes, two parents DHLBI 731 and S-12/30060 had average stability for grain yield and would be well adapted to array of environments. The cross combinations six crosses viz. RHRBI 138 x RHRBI 458, RHRBI 138 x S-12/30060, DHLBI 967 x DHLBI 731, DHLBI 967 x ICMB 98222, DHLBI 967 x S-12/30088, S-12/30060 x S-12/30074 and check Shanti had average stability and well adaption to all types of environment for grain yield. Hybrid S-12/30109 x S-12/30060 and check Dhanshakti had above average stability and adapted to poor environment, while five cross combination had below average stability for grain yield. Out of six stable cross combinations, three had one of the parent either DHLBI 731 or S-12/30060 which may have genes for average stability for grain yield which can further utilized in crossing programme in order to generate wide genetic variability for developing high yielding and stable hybrids/varieties/population of pearl millet.
