Genetical Analysis of Means for Early Generation in Bread Wheat (Triticum aestivum L.)

Six early generations (P1, P2, F1, F2, B1, B2) of tow crosses in bread wheat (Triticum aestivum L.). The first cross between Pandas and Gemeney, The second cross between S3-69 and S6-35, were used to study components of means for: maturity time, plant height, flag leaf area, grain yiely and its component. Tow models were applied in analyzing the component of the generation means for the studied characters in six generations. The results showed that the three parameters genetic model was adequate for the inheritance of spike length in the first cross and there were additive, dominance and epistatic effects on the other character.
