In order to evaluate the genetic diversity in some wheat genotypes through agronomic traits, an experiment was
conducted in a randomized complete block design with 9 wheat promising lines and Shahriar cultivar (control) and
two replications at Agricultural and Natural Resources Research Station, located 12 km south of Ardabil (Khalkhal
road) in 2012. Traits such as, total number of tillers, number of fertile tillers, number of infertile tillers, spike
length, grain weight per spike, plant height, biologic yield, peduncle length and weight, seed weight, days to
flowering, days to maturity, harvest index and grain yield were measured in this study. Cluster analysis was used
based on standardized data and WARD to classify the studied genotypes. cluster analysis were classified into three
groups: the second cluster that included genotypes 2 and 3 were high value in terms all evaluated properties
excluding peduncle weight, this cluster accounted for the highest average in terms of performance. So to increase
the performance, it can be used the clusters genotypes in the hybrids. Estimate the phenotypic and genotypic
coefficients for different traits indicated that genotypes had greater genetic diversity in terms traits such as total
number of tillers, number of fertile tillers, number of infertile tillers, spike length, peduncle weight, days to
flowering and days to maturity than other traits. Therefore, they can be used as selection criteria to improve yield.
