English Abstract

Twenty three entries of Faba Bean(Vicia faba) introduced from the International Center for Agricultural Research in the Dry Areas (ICARDA) in addition to local variety (French) were used in this study.

The seeds of 24 genotypes were sown under rain-fed conditions during season of 2012, in the farmer farms in Al-Shikan at 40 km North of Mosul, Iraq.

The experimental unit consisted of 2 rows ; 4m.

long and 30 cm apart.

The characters studied were number of days to 50 % flowering, plant height (cm), 1st height pod, number of branches, number of pods per plant, number of seeds per pod, seed yield , biological yield , harvest index %, weight of hundred seed.

Entries were significantly different at 1% level for all characters.

There was a high genetic variation for biological yield (kg /ha) , seed yield (kg /ha), weight of hundred seed .

The highest values of genetic variation coefficient were obtained for seed yield.

Broad sense heritability was higher for for all the study characters, between 0.619 for 1st height pod to 0.849 for biological yield (kg /ha) .

which is due to the high variability among these characters.

The expected genetic advance values as percentage of the total mean characters were high for seed yield, biological yield, harvest index and number of branches/ plant, moderate for plant height, 1st height pod, number of seeds per pod and 100 seed weight and few for number of days to 50 % flowering .

The phenotypic and genotypic correlation was positively significant between seed yield and biological yield (0.883 and 0.888) respectively , the genotypic correlation was higher than phenotypic correlation for most studied characters , which assures that the gene action plays the main role in these characters and enables the vegetables growers to depending on it in selecting the hereditary structure of high production from the faba bean.

The genetic path coefficient analysis showed that the biological yield and harvest index %, had a higher direct and indirect effects through the weight of hundred seed in the seed yield arranged in the second level.

This characters can be used in the programmer of plant breeding
