چکیده

یولاف به‌عنوان یکی از غلاتی که در اغلب نقاط دنیا کشت میگردد، دارای خواص غذایی و دارویی بسیاری است و این ظرفیت را دارد که در ایران نیز به‌طور اقتصادی کشت‌وکار شود، اما همانند بسیاری دیگر از محصولات زراعی تنش خشکی میتواند ازجمله موانع توسعه و تولید مطلوب آن باشد. لذا به­منظور مطالعه­ی تحمل خشکی 25 ژنوتیپ یولاف، مطالعه­ای در سال زراعی 92-1391 در قالب طرح بلوک­های کامل تصادفی با 3 تکرار در شرایط تنش خشکی و نرمال رطوبتی در مزرعه­ی تحقیقاتی پردیس کشاورزی و منابع طبیعی دانشگاه رازی کرمانشاه انجام شد. بر اساس عملکرد دانه در شرایط بدون تنش و دارای تنش خشکی، 14 شاخص مختلف تحمل و حساسیت به خشکی محاسبه شد. نتایج حاکی از وجود همبستگی معنیدار مثبت و بالایی بین MP، GMP، STI، YI، HAM، K1STI وK2STIبا عملکرد دانه در هر دو شرایط بود که نشان‌دهنده‌ی مناسب بودن آنها برای غربالگری ژنوتیپهای متحمل به خشکی است. بر اساس تمامی محاسبات و تجزیههای آماری انجام شده ازجمله شاخصها، روش رتبهبندی، تجزیه به مؤلفههای اصلی، بایپلات و تجزیه خوشهای، ژنوتیپهایUfrgs948886 وEuro به‌عنوان ژنوتیپهای با عملکرد بالا تحت هر دو شرایط دارای تنش و بدون تنش خشکی شناسایی شدند.
