Abstract :
Wheat (Triticum aestivum) is most important cereal crop in Iran. It is growing in a wide range of weather conditions and is compatible species in cereals. Wheat is the staple food of man. To study the genetic diversity in 20 wheat genotypes in Ardabil province in terms of the main traits morphological and phonological and yield and its components and to investigate the relationships between the various characters through multivariate statistical methods, a test was done in augmented design in 7 blocks. Correlation analysis showed that traits of days to flowering had the highest positive and significant correlation with yield and grain weight showed a significant and negative correlation with yield. The results of factor analysis revealed five factors are explained together 81.4% of the total variation. Regression analysis through decline method for predict the yield respectively plants brigade , the number of days to flowering, stem diameter, number of seeds per plant and days to fill heading was used into in models. The results of cluster analysis classified genotypes evaluated in 10 distinct groups.
