Some Yield Parameters of Wheat Genotypes

To study the effect of the cross direction in bead
wheat, three hybrid combinations (Babyle 113, Iratome), (Sawa,
Tamose2) and (Al Hashymya, Al Iraq) were tested for plant height,
spike and awn length, number of grains per spike, 1000-grain weight,
number of tillers/m and grain yield. The results revealed that the
direction of the crosses significantly effect on the number of
grains/spike, number of tillers/m and grain yields. Grain yield was
positively and significantly correlated with 1000-grain weight,
number of grains per spike and tillers. Depend on the results of
heritability and genetic advance it was suggested that 1000-grain
weight, number of grains per spike and tillers should be given
emphasis for future wheat yield improvement programs.
