In: Zagazig journal of agricultural research 2009.v.36(1)Summary: This study was aimed to find out some biochemical and molecular genetic markers associated with earliness trait in bread wheat (Triticum aestivum L.). Six parental genotypes of wheat were used that represent a wide range of variability for earliness trait namely; Sids- 4 and Sakha- line (early), Sakha-93and Gemmeiza-7 (medium), Gemmeiza-9 and Milan( late). F1 seeds were obtained for five crosses were chosen to make biochemical analysis using SDS - PAGE Banding Pattern. These crosses were (Sids-4 x Sakha-line), (Sakha-93 x Gemmeiza-7), (Gemmeiza-9 x Milan), (Sids-4xMilan) and (Sids-4 xGemmeiza-7). The obtained results showed that, there are a biochemical and molecular markers associate with earliness trait in wheat. Two bands with molecular weight ranged from (90.276 to 77.181 KD) in the cross (Sids-4 x Milan), that appeared only in F₁. So, these bands could be used as a selective biochemical marker for earliness trait in wheat.
