Genetic analysis for quantitative traits in maize using generation mean analysis

الملخص EN

The choice of breeding procedure depend on the type and relative amount of genetic components which control the traits to be selected.

The objective of this study is determine some genetic parameters using generation mean analysis method, six generations (p1,p2 and F1,F2.BC1,and BC2)from crosses of maize (OH40X Un44052) and (IK8X HS).

The results showed significant differences among generations in plant height Number of Kernels row−1, 300 .kernel Weight and grain yield.

Most additive, dominance, additive ×additive× additive x dominance and dominance x dominance affect on the study traits, However, dominance values were more than additive values for all traits which justifies the production of hybrid varieties in maize .Broad sense heritability of all traits were higher than narrow sense in both crosses.
