ارزیابی ژنوتیپ های پیشرفته گندم دوروم در شرایط زارعین

To accelerate in transformation of research results, six improved durum wheat lines, were evaluated in Dehdasht and Likak regions in 2009. They were planted in randomized complete block design (RCBD) with 4 replications, through 300 kernel per square meter density and 25 centimeter row spacing. During vegetative and reproductive stages, different characters were recorded. The most important traits were: days to heading, plant height, thousand kernel weight and grain yield. Based on simple and combined analysis of variance on grain yield, there was no significant difference between lines and locations. Although, occurrence of sever heat and drought stresses during growth period, considered lines showed relatively good performance. However, Due to existence of Dehdasht cultivar which is released recently, increasing of grain yield and strength of agronomic traits for candidate lines is necessary.
