Abstract

 

The study was executed to assess the extent and pattern of genetic variability of Ethiopian mustard genotypes with respect to seed yield and its related traits in 49 Ethiopian mustard land races at Holetta Agricultural Research Center, Ethiopia. The experiment was carried out in a simple lattice design. Univariate analysis has shown that there was significant different variation among genotypes in all traits compared. The significant difference indicates that the existence of genetic variability among the accessions that is important for selection program and breeding. Multivariate analyses resulted in the formation of four clusters and have shown the presence of substantial genetic diversity among the genotypes. The present study also showed that geographical diversity could not necessarily be an index of variation and the factors other than geographic diversity such as genetic drift, selection pressure, closeness in pedigree and environment may be responsible for differential grouping of genotypes. The present study revealed the presence of considerable variability among genotypes for all traits. The presences of substantial genetic diversity among genotypes tested indicate that there is good opportunity to improve seed yield and its related component traits using the tested genotypes.

Keywords: Ethiopian mustard, Genetic diversity, univariate and multivariate analysis, seed yield related traits
