| تعداد 277 مورفوتیپ از ژرم‌پلاسم جو زراعی بانک ژن گیاهی ملی ایران، متعلق به یازده استان کشور با اقلیم گرم و خشک، از نظر تحمل به خشکی مورد ارزیابی قرار گرفتند. مورفوتیپ‌ها در دو آزمایش تنش خشکی و نرمال کاشته شدند. بر اساس عملکرد دانه، شاخص‌های تحمل به تنش محاسبه شدند. بررسی آماره‌های توصیفی عملکرد در هر دو شرایط و شاخص‌های تنش نشان داد که شاخص STI دارای بزرگ‌ترین ضریب تغییرات بود. شاخص‌های GMP و STI براساس همبستگی بالا با عملکرد دانه در شرایط نرمال و تنش خشکی به عنوان مناسب‌ترین شاخص‌ها شناسایی شدند و 59 مورفوتیپ در گروه متحمل به خشکی قرار گرفتند که از بین آن‌ها مورفوتیپ‌های 70227 از یزد، 2/6507، 6436 و 1/6252 از بوشهر، 70013 و 70014 از کرمان، 2/6652 از خوزستان، 6421 از خراسان و 70017 از سیستان و بلوچستان دارای مقدار شاخص STI بیشتری بودند و به عنوان مورفوتیپ‌های برتر در این تحقیق شناسایی شدند. بر اساس فاصله اقلیدسی بین منشاء مورفوتیپ مورد بررسی، مورفوتیپ‌های سیستان و بلوچستان و بوشهر، کمترین و مورفوتیپ‌های خوزستان و لرستان بیشترین شباهت را داشتند. در نمودار پراکنش منشاء مورفوتیپ‌ها، مبتنی بر مقیاس‌بندی چندبعدی، استان‌های لرستان، فارس، هرمزگان، خوزستان و مرکزی در اطراف نمودار و دورتر از سایر استان‌ها و بوشهر و اصفهان در نزدیکی مرکز نمودار واقع شدند. از آن‌جا که مورفوتیپ‌های مورد بررسی در این تحقیق بومی اقلیم گرم و خشک کشور بودند، تحمل بالایی نسبت به تنش خشکی نشان دادند و تنوع ژنتیکی بالائی از این نظر در ژرم‌پلاسم وجود داشت. | ||

| چکیده [English] | ||
| A total of 277 barley landraces belonging to barley collection of National Plant Gene Bank of Iran, originating from eleven provinces in arid-zone of Iran were evaluated for drought tolerance. The genetic materials were planted in two normal and stress experiments in augmented design scheme. The grain yield was measured and stress tolerance indices were computed. Results of descriptive statistics indicated that STI had higher coefficient of variation (56.56%) than the other stress indices. GMP and STI with large coefficient of correlation with grain yield under stress and normal conditions were identified as the best indices. Fifty-nine morphotypes were located at group A of Fernandez category, among them, 70227 from Yazd, 6507.2, 6436 and 6252.1 from Boshehr, 70013 and 70014 from Kerman, 6652.2 from Khozestan, 6421 from Khorasan and 70017 from Sistan and Balochestan had the largest STI and were identified as superior morphotypes in this research. Based on Euclidean distance between origins of the accession, morphotypes of Sistan and Balochestan had the lowest and morphotypes of Khozestan and Lorestan had the highest similarity. Provinces Lorestan, Fars, Hormozgan, Khozestan, and Markazi were located at the margin of scatter plot drawn based on multi-dimensional scaling, while Boshehr and Isfahan were located near to origin. Since the morphotypes in this research were all originating from arid climates, most of them exhibited high tolerance to drought stress, but a high genetic diversity was observed in local germplasm of barley for drought tolerance. | ||
