Stability Analysis and G X E Interaction for Grain Yield in Pearl Millet [Pennisetum glaucum (L.) R. Br.]

Genotype x environment interactions and stability parameter analysis are of major importance to sort out high yielding and stable hybrids. 60 hybrids and 16 parents were evaluated during kharif 2011 with two sowing dates [11^th July, 2011 (E₁) and 2^ndAugust, 2011 (E₂)] and during summer 2012 with one sowing date [16^th February, 2012 (E₃)] to identify stability for grain yield in pearl millet. G x E (linear) and G x E (non-linear) were found significant for days to 50% flowering, days to physiological maturity of grains, dry ear head weight per plant, grain yield per plant, test weight of 1000 grain. Total biomass per plant, stover yield per plant and panicle harvest index. Among the hybrids, JMSA-9904 x AIB-11, ICMA-97111 xJ-2526, ICMA-97111 xAIB-2, ICMA-98444 x 236SB, ICMA-98444 x AIB-11, ICMA-98444 x AIB-20, JMSA-20041 x J-2507, JMSA-20041 x J-2490 and ICMA-04999 xAIB-11 had average stability, which indicated that these hybrids would be well adapted over range of environments.
