Abstract
The present investigation was undertaken for evaluation of pearl millet {Pennisetum glaucum
(L.) R. Br.} hybrids under diverse climatic conditions in Haryana to study genotype x environment
interaction (G X E), co-relation between characters, direct & indirect effects on grain yield and
identification of stable hybrids for different characters over different environments. The material
for the present investigation comprised of 30 pearl millet hybrids, including two checks viz. HHB-67
Impr., HHB-226. The experimental material was grown at three different sites of CCS Haryana
Agricultural University i.e. Genetics & Plant Breeding Research Area; Dry Land Agriculture Research
Area; and RRS, Bawal (Rewari) during Kharif 2011 in a randomized block design with three
replications.
The estimates of stability parameters of individual hybrids revealed that hybrid ICMA 99111
X HBL 11 was the most ideal for grain yield. It exhibited stable performance across the environments
for ear girth, ear length and protein content also. Correlation study revealed that grain yield was
significantly and positively correlated with ear girth in all test environments and with ear length in E1
and E3, while with effective tillers per plant in E1 and E2 environments.
The path coefficient analysis suggested the importance of ear girth, ear length, effective tillers
per plant, nodes per tiller, days to 50 per cent flowering and days to maturity, as these had positive
direct and indirect effects on grain yield. Therefore, selection for higher yield will be useful if it is
based on traits such as ear girth, ear length and effective tillers per plant.
