| Abstract | ||
| Afield experiment was conducted at AL- Mashroa area / Babylon Province during 2013and 2014 seasons to find out the performance of five cultivars of rice (Amber33,Yasmin,Mishkhab,Furat and Abassiah) and estimate their GCA and SCA for the output hybrids using RCBD with three replicate . Results can be summarized as follow . 1-A high significant differences were observed for square means of GCA and SCA for all the characters under study , The parent (Anber33) had a higher GCA for number of panicles . plant-1 and 1000 grain weight ,while parent (Furat) gave higher means of number of grain .panicle-1 , hybridization between (Amber33×Yasamen) gave higher mean of 1000 grain weight and grain yield (0.78,12.14), respectively. 2- Board heritability percent was higher for all the traits while narrow heritability percent was medium to low in the qualities studied .The ratio between them was less than one . The dominance mean on the other hand was more than one . It could be concluded that some cultivars particularly (Amber33) and the hybrids of (Amber × Yasamen) can be used to induce a individual hybrids of high yield ,because their traits were pioneer to be used and continuous their breeding programs. | ||
