Stability of grain yield and its contributing traits in white and grey grain hybrids of Perl millet (Pennisetum glaucum)
2009
Arya, Rajesh Kumar | Yadav, H P
Sixteen white and 16 grey grain color hybrid of pearl millet along with check HHB 94 were evaluated under four environments for stability parameter, viz regression co-efficient (bi) and mean square deviation (S2di0 from linear regression along with per se performance. Data were recorded for five yield related character, viz grain yield number of effective tillers, ear length, ear girth, ear weight and 1000-grain weight. The significant linear and non-linear type of G x E interaction was observed for all the character, but the magnitude of linear type of G x E interaction was higher for most the character except ear length and ear girth. The two white and one grey grain colour hybrids, viz ICMA 94222 x H 77/833-2 and ICMA 94222 x 78/711 and HMS 6A x H77/833-2, respectively were ideal for the test environments; only one white grain hybrid (HMS 36A x 99) was ideal for favorable environments and two white grain hybrid, vi HMS 36A x ERC, ICMA 9711 x 99 and 1 grey (ICMA 9411 x ICR 159) were ideal for the poor environments.
