Genetic Divergence Study of Durum Wheat (Triticum durum Desf) Genotypes Grown in Tigray, Ethiopia

Muez Mehari, Solmon Fantaw, Haddis Yirga and Adhiena Mesele

Abstract:
In any crop improvement program, the presence of genetic divergence is an important entry point for selection and hybridization. A trial was executed using twenty durum wheat genotypes with the objective of determining the genetic divergence and trait variability in durum wheat genotypes. The study was carried out in Ofla district, Tigray during the 2014 cropping season using a randomized complete block design. The inter-cluster distance of the twenty durum wheat genotypes ranges from 0.57536 in cluster one to 212.02335 in cluster four. The maximum inter-cluster distance was between cluster two and cluster four which was 212.0233. The clustering analysis classified the twenty durum wheat genotypes into four distinct clusters and the first cluster accommodates 15 durum genotypes including the two release genotypes. The second cluster consists of three durum wheat genotypes. The third and fourth clusters similarly contained each one durum wheat genotype. Cluster two and cluster four was highly divergent and crossing program between these clusters could result better segregating population in durum wheat breeding program.
