| Abstract | ||
| Sainfoin is a forage legume that can be cultivated in irrigated and rainfed areas. This study was conducted to study genetic diversity in agro-morpho phonological traits of Onobrychis germplasms for exploiting in sainfoin breeding programs. A total of 159 accessions belong to 20 species, naturally distributed in the country, were planted in field. Nineteen agro-morpho phonological traits were characterized in these materials over 2 years. There was high degree of diversity in the studied traits. Species were divided into 4 clusters based on cluster analysis. In this analysis, those species with similar agronomic traits revealed in the same cluster. In factor analysis, the first factor was affected by forage quantitative and qualitative traits, whereas generative characters had the most effect on the second factor. Produced bi-plot in factor analysis confirmed cluster analysis results. Based on theses analysis, wild species of O. pulchell Schrenk., O. hohenackeriana C.A.Mey, O. subnitens Bornm., O. chorassanica Bungeand O. schahuensis Bornm wereproposed as suitable species for forage production. | ||
