Abstract
Yield is one of the main fundamental breeding objectives in case of wheat. Data were recorded on six wheat "varieties/lines and five F4 populations to compute coefficient of variability, heritability and expected genetic advance for flag leaf venation, epidermal cell size, stomatal frequency, stomata size and grain yield per plant. Ranges of estimates of heritability for these characters were 37.13-66.67%, 67.20-80.08%, 56.90-69.64%, 49.12-64.00% and 77.R9-84.67'f,J, respect ively and those of genetic advance were 0.18-0.46, 253J)()-5B.OO, 0.69-0.92, 2.25-3.45 and 7.()8-1O.12, in the same order.
