Abstract

Seven bread wheat genotypes (line 39, line 54, New valley, V92/17,
V99/17, Sakha 8 and Sahel 1) were crossed in a half-diallel mating design
and were planted to determine their genetic behavior under water stress
conditions. Results were recorded on days to heading, plant height, no. of
spikes/plant, no. of grains/spike and grain yield/plant. Results for all traits
revealed highly significant (P < 0.01) differences among genotypes under
water stress conditions. General (GCA) and specific (SCA) combining
ability were found to be significant or highly significant for all traits,
indicating the importance of additive and non-additive gene actions in
controlling the performance of these traits in all genotypes. In general, for
all studied traits, the magnitude of mean squares due to GCA was higher
than that due to SCA, suggesting that additive was more important than
non-additive gene effects in the inheritance of these traits. One superior
cross (Line 39 x V 92/17) for grain yield and two crosses (New valley x V
92/17 and Line 54 x New valley) for no. of grains/spike under water
stress were considered as promising hybrids for improvement purpose.
Moreover, they involved good combiner parents which can be used to
improve any of these features.
