| Abstract | ||||
| Genetic materials consisted of 42 faba bean (Vicia faba L.) landraces and two commercial cultivars (Giza 3 and Sakha 1) maintained at the National Gene Bank in Egypt were sown at El-Gemmeiza Agricultural Research Station in 2015/2016 and 2016/2017 to examine genetic diversity and relationships among landraces of faba bean collected from different regions in Egypt using morphological characters, yield and yield components. Results indicated that landraces No. 13, 16, 20, 21, 23, 28, 29, 32 and 36 are good to improve the performance of seed and seed yield characters through breeding program. Days to 50% flowering had significant and negative correlation with number of tillers/plant and stem intensity of anthocyanin correlation, and days to 50 % flowering had significant and positive correlation with days to 90% maturity, so these morphological characters can be used as a marker assisted selection for early maturity. Seed yield/plant showed positive and significant correlation with each of pods number/plant, seeds number/plant and 100-seed weight. These findings indicated that selection for each or both of No. of pods, seeds and 100-seed weight would be accompanied by high yielding ability. The major contributing traits for the diversity in the first principal component (PC1) were number of seeds per plant, plant height and number of pods per plant. For the second principal component (PC2), 100- seed weight and plant height were major contributors for the diversity. Cluster analysis indicated that maximum similarity was recorded between landraces No. (12 and 27). Minimum similarity was computed between landraces No. (9 and 13). | ||||
