Abstract

To study the GENETIC VARIATION in some DURUM WHEAT lines, 102 pure lines from wheat Collection of Cereal Research Department, Seed and Plant Improvement Institute were evaluated using augmented design in six blocks with four durum whear check cultivars (Yavaros, Arya, Dena and Shotordandan) in the experimental field of Faculty of Agriculture, Islamic Azad University, Karaj Branch, during 2008-2009 cropping season. Morphological and phisyological traits were recorded during the growth period. Analysis of variance of the data indicated significant differences among the genotypes for most traits. Correlation between grain yield and biological yield, day to physiological maturity, grain/spike and spike length was positive and significant. Linear regression indicated that biological yield, harvest index and day to heading explained 84% of yield means variance among the lines. PATH ANALYSIS results showed a direct positive and high effect of biological yield and harvest index on grain yield, but day to heading had an indirect and negative effect on grain yield. The accessions were divided into four groups by cluster analysis based on Ward method, using squared euclidian distance coefficient. Results demonstrated that traits such as day to heading and biological yield could be used as selection indices in breeding programs for grain yield improvement in DURUM WHEAT.
