Abstract
The present investigation on “G x E Interaction for Morpho-Physiological
Aspects In Bread Wheat [Triticum aestivum, (L.)]” was undertaken at three
locations viz. Niphad, Rahuri and Savalvihir under timely sown irrigated (TSI)
and late sown irrigated (LSI) conditions during Rabi-2013-14. The experimental
material consist of twenty new bread wheat genotypes developed at Agricultural
Research Station , Niphad and three check varieties. Experimental material was
grown in a randomized block design with three replications over six
environments.
The mean sum of squares due to genotypes were significant for all the
nineteen 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 all nineteen characters which indicated that
genotypes interacted differently with environmental variation for the said characters. Highly significant values of mean squares due to environments (linear)
for all the characters indicated that the linear responses of genotypes to
environment differed significantly for the said characters; while mean square
values due to G x E (pooled error) were also significant for all the characters.
