Abstract

Common bean (Phaseolus vulgaris L.) also known as haricot bean, snap bean, navey bean, and kidney bean. It is seed propagated and true diploid (2n = 22). Low yield is a major problem of common bean in Ethiopia. So, the morphological characterization of common bean landrace is essential to improve yield and yield related character through selection. The objective of this study was to characterize Common bean of landraces collected from different parts of Ethiopia. In this study, one hundred common bean landraces were evaluated in simple lattice design at Jimma Agricultural Research Center, Melko. Considerable variation in plant growth habit, Type-II (indeterminate bush) was the most prevalent among the accessions (55%), followed by Type-I (determinate bush) (45%) growth habits. The percentage frequencies of the qualitative classes varied from 4%-84%. The Hꞌ values varied from 0.190 for pod beak position to 0.642 for seed color. Characters with wide phenotypic diversity index was observed in seed color (Hꞌ=0.642) seed coat color (Hꞌ= 0.624), pod color (Hꞌ=0.622), and seed shape (Hꞌ=0.582) indicating widely diversified for these characters. On the other hand, pod beak position (Hꞌ=0.190) showed relatively the lowest diversity. The high diversity of bean landraces observed in this study, is in part due to farmer’s customary seed exchanges. Frequent mutations and genetic recombination are the other possible causes of high diversity of the bean landraces studied. In general, this study showed that the collection has a relatively important diversity. This genetic diversity can be exploited in improvement programmes. However, the present result based on morphological alone can’t make definite conclusion. As a result, it is recommended that molecular and other quality traits like protein content studies have to be carried out.
