Abstract

The present investigation was carried out at Sids Agricultural
Research Station, Agricultural Research center (ARC.), Egypt, during
three successive seasons of 2013-2014, 2014-2015 and 2015/2016. The
objective of this study to estimate of mean performances, gene action,
heterosis and inbreeding depression for grain yield and its components
and characters. Six populations (P1, P2, F1, F2, BC1 and BC2) for two
crosses were used in this study coming from (P1x P2) and (P3 x P4). The
estimates of the six parameters, i.e. additive (d), dominance (h), additive
x additive (i), additive x dominance (j) and dominance x dominance (I)
and means (m), the mean effects were highly significant for all studied
traits in the two crosses, indicating that these traits are quantitatively
inherited. For heterosis, highly significant heterotic effect positive was
found between crosses for 1000 kernels weight in two crosses and
number of grains per spike in second cross. On the other hand
inbreeding depression showed highly significant negative with first cross
and positive with second cross. In general first cross was highly
significant negative, but in second cross grain yield per plant, 1000
kernels weight and number of grains per spike was non-significant. In
two crosses, regarding potence ratio value were more than unity for all
traits under study except number of grains per spike with first cross and
days to heading in second cross.
