Genetic Determination for Some Drought Related Leaf Traits in Bread Wheat
Muhammad Aslam Chowdhry,
of gene action was studied in a 5 x 5 diallel cross of bread wheat involving
five genotypes namely 8073, 8177, 6039-4, Pb-96 and MH-97. Highly significant
differences were observed for all the traits studied. Over-dominance was
observed in hygrophilic colloids and stomata size. Flag leaf area, leaf
venation and stomatal frequency were governed by partial dominance with
additive gene action. Epidermal cell size was controlled by partial dominance.
Non-allelic interactions were observed in flag leaf area and stomata size.
