Qualitative Traits Variation in Sorghum (Sorghum Bicolor (L.) Moench) Germplasm from, Eastern Highlands of Ethiopia

Article

Abstract

Forty-five sorghum germplasm growing in the Eastern Highlands of Ethiopia were evaluated for 10 qualitative traits. Phenotypic frequencies between the accessions from each of the nine Aanaas and Alemaya University, grouped in 10 localities were tabulated. Phenotypic diversity index, H′, was analysed and the result indicated the between localities component of diversity to be relatively smaller than the variation in H′ among characters within localities. The value of H′ for all sample germplasm ranged from 0.36 to 0.95 with a mean of 0.71. The results showed that there is a wide morpho-agronomical diversity among the sample germplasm studied. This information can be used for the conservation of these germplasm resources and future improvement work of the sorghum crop.
