Abstract

In order to study the genetic diversity of Durum wheat genotypes in 2016-2017, 18 durum wheat genotypes were cultured in a randomized complete block design with four replications under two conditions of supplementary irrigation and rainfed condition at Research Station of Kachersaran Dryland Research Center. The cluster analysis results showed that the genotypes were classified into three groups in both conditions. In rainfed and irrigation supplementary conditions, group 3 had the highest seed yield. The lines 4, 15, 16 and 17 were in the third group in both conditions that can be considered as drought tolerant genotypes in breeding programs. In factor analysis, four factors were identified both in rainfed conditions and in supplementary irrigation conditions, which explained 84.88 and 81.88 percent of data variability, respectively.
