| Abstract | ||||
| The Present investigation was conducted to the study the inheritance of some quantitative traits on faba bean (Vicia faba L.) as well as evaluation of ten genotypes with two check cultivars (Sakha1 and Giza 843). A randomized complete blocks Design (RCBD) with four replicates, was used two field experiments were carried out at Tag EL-EZZ Agricultural Research Station, Dakahlia Governorate during 2007/2008 and 2008/2009 seasons. The analysis of variance had significant effects on faba bean seed yield and yield components, so the results cleared the presence of genetic variability among studied genotypes. In relation to the mean performance both faba baen genotypes 1556/914/2001 and 1423/653/2000 gave the highest values of number of branches/plant(4.10 and 4.13), number of pods/plant (16.73 and 16.60) and seed weight(g)/plant(24.40 and 23.33) than those other tested faba bean genotypes and reflected on faba bean seed yield /faddan (13.85 and 13.25 ardab). In addition, both faba bean genotypes out yielded the check cultivar, Sakha 1 by 28.1 and 29.1% for number of branches/plant ,25.5 and 24.5% for number of pods/plant and 18.6 and 13.4% for seed yield/ faddan, respectively. These findings could be useful to select high yielding materials to exploit in the breeding program. The analyses of parameters of genetic variability showed little difference between GCV and PCV for number of pods/plant (21.0,22.3) and 100-seed weight (11.5,12.8).Indicating a little influence of environmental effect on these characters. However, PCV was higher then GCV for seed yield (ardab/fad.) and seed weight/plant, suggesting a significant environmental effect, which is not unexpected for such agronomic characters. On the other hand, high heritability and very high GA% value were obtained for plant height (80.7, 1300%), reflecting that the trait could be further improved through individual plant selection. The results clearly show that positive and significant correlation between number of branches/plant and number of pods/plant(0.906), and also between seed weight/plant and seed yield/faddan, while the correlation coefficient between remaining studied characters was non significant. Significant correlation between characters indicating the selection in both characters was affected with the other characters and these are important for breeding programs. | ||||
