چکیده | ||
Salinity stress represents a significant abiotic factor that adversely impacts crop production. Although barley is recognized as a salinity-resistant species, all stages of its growth are susceptible to the detrimental effects of salinity stress. The present study aimed to identify promising irrigated barley lines exhibiting high grain performance and stability under conditions of salinity stress. Eighteen promising barley lines, along with two local checks (the Golshan cultivar and MBS-98-10), were evaluated across three saline regions (Yazd, Isfahan, and Birjand) during the 2021-22 and 2022-23 cropping seasons. The results of the combined analysis of variance for grain yield indicated no significant effects for year, genotype×location, and genotype×year interactions; however, significant effects were observed for location, genotype, year×location, and genotype×year×location interactions. Mean comparison results revealed that genotypes G8, G4, G11, G13, and G14 exhibited the highest grain yields relative to the other genotypes. To assess yield stability, both non-parametric parameters (S (1), S (2), S (3), and S (6)) and parametric parameters (coefficient of variance, Shukla’s stability variance, Wricke’s Ecovalence, and Kang’s rank-sum) were employed. The findings identified genotypes G4, G13, and G14 as lines with desirable and stable yields, which may not only serve as new cultivars in salinity-affected regions but also contribute to future breeding programs aimed at developing new salt-tolerant barley lines. | ||

چکیده [English] | ||
تنش شوری یکی از عوامل مهم غیرزیستی است که تولید محصولات را مختل می کند. اگرچه جو یکی از گیاهان مقاوم به شوری است، اما تمام مراحل رشد آن تحت تأثیر اثرات منفی تنش شوری قرار دارد. در این مطالعه برای شناسائی لاینهای امید بخش جو آبی دارای عملکرد مطلوب و پایدار تحت شرایط تنش شوری، 18 لاین امید بخش جو به همراه دو شاهد (رقم گلشن و لاین MBS-98-10) در مناطق متاثر از تنش شوری (اصفهان، یزد و بیرجند) در سال های زراعی 02-1400 مورد مطالعه قرار گرفتند. نتایج تجزیه واریانس مرکب عملکرد دانه نشان داد که اثر ساده سال و اثرات متقابل ژنوتیپ ×مکان و ژنوتیپ ×سال معنی دار نبوده ولی اثرات ساده مکان، ژنوتیپ ، سال×مکان و ژنوتیپ×سال×مکان معنی دار می باشند. مقایسه میانگین نشان داد که ژنوتیپهای G8، G4، G11، G13 و G14 نسبت به سایر ژنوتیپها دارای عملکرد بالاتری بودند. به منظور بررسی عملکرد دانه از آماره های ناپارامتری Si1، Si2، Si3، Si6 و پارامتری ضریب تغییرت، واریانس پایداری شوکلا، اکووالانس ریک و مجموع رتبه کنگ استفاده شد. نتایج نشان داد که ژنوتیپ های G4، G13 و G14 دارای عملکرد مطلوب و پایدار بوده که نه تنها به عنوان یک رقم جدید می توانند مورد استفاده واقع شوند بلکه در برنامه های به نژادی آینده برای تولید لاینهای جو مقاوم به شوری مورد استفاده واقع شوند. | ||
