| Abstract: A several field experiments were condncted in a privat field in AL- Musaib project, 30 km north Babylon Govcrnarat , during spring and fall seasons of 2012 and 2013,two inbreds (OH40 , Sy7)were planted in spring of 2012, then they were crossed to obtain F1 plants .F1 and the two inbreds seeds were sawn in fall of 2012. F1 plants were back crossed with their parents (OH40 , Sy7) to obtain BC1 of crossing them. F1 plants were self pollinated for F2 . A spring experiment was conducted in the spring of 2013 by RCBD with 3 replications to compare between the 6 genotypes with to estimate gen action to yield and its components as grain well as yield .Results show a significant differences in all traits studied .The Sy7 was superior on OH40 ,and F1 hybrid gave the highest means of row number/ear , grain number/row , 1000 grain weight and total grain yield .while ,back cross plants (F1 × Sy7) means higher than (F1 × OH40( .This confirm the importance of Sy7 parent in increasing inheritance to of traits .Gene action non additive was controlls the yield and its components. | ||
