بررسی خصوصیات زراعی وعملکرد دانه ژنوتیپ های گندم دوروم درآزمایشات مشاهده ای و مقایسه عملکرد بین المللی درشرایط دیم گرمسیری و نیمه گرمسیری

In order to achieve high yielding genotypes and grain quality of durum wheat for using in spaghetti production industries that have the good traits such as tolerance to environmental stresses such as drought and heat, resistance to diseases and pests, early and large seed, this study conducted in the form of a item observational trial (40th IDSN) with 145 genotypes in two stations (Moghan and Ilam) and a item international yield trial (40th IDYN) with 50 genotypes and two Replicates in Gachsaran, Gonbad and Moghan stations. The genotypes that received from world international research institute for wheat and maize (CIMMYT) with Dehdasht check cultivar studied and evaluated in four agricultural research station including Gachsaran Gonbad, Moghan and Ilam. During the growth period from various agronomic and morpho-physiologic traits of genotypes such as date and percentage of green, growth power, plant height, days to heading and maturity, reaction to important diseases and the like were note. Observational trial 40th IDSN after harvest in each area, new genotypes grain yield were compared with check grain yield using chart, in trial 40th IDYN on seed yield of genotypes analysis of variance was performed and means by least significant deviation (LSD) method were compared with Dehdasht check varieties. In total of trials, 72 excel genotypes based on desired agronomic traits and grain yield for supplementary evaluations were selected for later years.
