Abstract:

In order to study and group a few of wheat genotypes, an experiment was conducted in random block design with three replications at Agricultural Research Station in Islamic Azad University in Ardebil in the crop year of 2013. In this study the traits including remobilization of stored assimilates, contribution of stem reserves in yield, Eigen-weight of stem in maturity, carbohydrates transport efficiency, stem efficiency in transporting the stored materials and seed weight were measured. Average random samples were used to analyze data. After standardization of data, distance modulus squared Euclidean distance cluster analysis was done in WARD method and genotypes were categorized in 2 groups. The best cut place was chosen using detection function. First group with 6 genotypes including Sabalan, Fengkang, Trakia, Alamout, Bezostaia and Garak 79 genotypes which were the highest considerably all studied characteristic except for eigen-weight of stem at maturity. So this group can be introduced as the best one in measured traits (Table 1 and Figure 1). The second group with 4 genotypes including Azar, Pishtaz, Siosson and Konica2002 were low value genotypes in measured traits. The results from ANOVA and discrimination function analysis show validity of studied genotypes grouping.
