[ 1 ] - ارزیابی شکاف عملکردی لاین‌ها و ارقام گندم دوروم در شرایط تحقیقاتی و مزارع زارعین

بررسی عملکرد گندم دیم در استان کرمانشاه طی سال‌های 1363 تا 1392 نشان می‌دهد که تغییر محسوسی که نشان‌دهنده یک روند رو به رشد باشد مشاهده نمی‌شود و طی این سال‌ها عملکرد گندم دیم بین 600 تا 1400 کیلوگرم در نوسان بوده است. بررسی ظرفیت قابل حصول و واقعی عملکرد، تعیین فاصله بین این دو (Yield gap) و شناسایی عوامل محدودکننده دستیابی به عملکرد قابل حصول و توسعه راهبردهای مناسب می‌تواند به بهبود عملکرد ا...

[ 2 ] - Study of Grain Yield and Agro-Physiological Characteristics of Some Promising Rainfed Bread Wheat Genotypes under No-Till Condition

   In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...

[ 3 ] - Evaluation of genotype × environment interaction in durum wheat (Triticum turgidum var. durum L.) regional yield trials

The objective of this experiment was to analyze genotype × environment (GE) interaction for grain yield of 20 durum wheat genotypes to identify the yield stability and adaptability of genotypes using GGE biplot method as well as some univariate stability statistics. The genotypes were evaluated in three rainfed stations of Sararood (Kermanshah), Maragheh and Shirvan, Iran under both rainfed and...

[ 4 ] - Evaluation of Agro-Physiological Characteristics and Drought Tolerance in Some of Durum Wheat Breeding Genotypes

In order to study of agronomic, physiological characteristics, drought tolerance and to identify  Agro-physiological traits associated with drought tolerance, 19 durum wheat genotypes consisting of 17 advanced breeding lines and two control cultivars (Saji and Zahab) were evaluated in a randomized complete blocks design with three replicated under both stress (rainfed condition) and non-stress ...
