GENETIC ANALYSIS FOR EARLINESS, PLANT HEIGHT AND KERNEL WEIGHT IN TWO BREADWHEAT CROSSES UNDER NORMAL AND SALINE SODIC SOILS

Published on

A set of six populations, viz. both parents, Ft, F2, BCt and BC2, derived from the crosses
Kharchia 6S X Raj 3077 and Kharchia 6S X Lok 1 of breadwheatwas evaluated under normal
and saline sodie soils to estimate the type of gene effects for days to flowering, days to
maturity, plant height, and 100-kernel weight. In general, all these traits were
predominantly governed by additive gene effects in both the crosses under normal and
stress environments, though the nonadditive gene effects were also important in some of
the combinations. Hence intermating in early generations followed by selection could be
successfully adopted for improvement of the traits studied.
