Abstract

In a field trial, a database of qualitative traits associated with agromorphological and quality traits of winter wheat (Triticum aestivum L.) has been collected. The present study aimed to determine the relationships between the winter wheat traits of productivity and quality with traits of Distinctness, Uniformity and Stability (DUS) testing. In addition, according to grain yield and significantly correlated traits, investigated genotypes will be clustered. Grain yield was significantly positively correlated with the number of days to heading, time of ear emergence, and plant growth habit. Based on the grouping of the winter wheat genotypes using the Euclidean distance algorithm, wheat genotypes were separated into five main clusters according to the similarity of those four traits. The grouping pattern was very origin homogeneous in each group, and the grouping pattern of genotypes appeared to be associated. The highest contributor to a grouping of genotypes was grain yield. The established result pertain to the potential for increasing the grain yield of winter wheat.
