TAILIEUCHUNG - Evaluation of drought and salt resistance during the germination of selected durum wheat lines
Seventeen selected lines of Azerbaijani durum wheat were tested for drought and salt resistance with respect to parameters of adaptability and stability. The samples were studied during germination under water, salt and thermal stress environments, as well as under normal growing conditions. | Tr.

MAMMADOV Institute of Genetics & Plant Breeding, Azadlig Street, 155, GSP 370106, Baku-AZERBAIJAN Received: Abstract: Seventeen selected lines of Azerbaijani durum wheat were tested for drought and salt resistance with respect to parameters of adaptability and stability. The samples were studied during germination under water, salt and thermal stress environments, as well as under normal growing conditions. Of the lines selected, Leucurum 242h93, Melanopus 63h93 and Apulicum 317h93 proved to be productive and stable in stress conditions, and they were determined to be valuable initial material in wheat breeding for drought and salt resistance. Key Words: adaptibility, drought resistance, germination, salt resistance, stability, stress environment. Seçilmiş Makarnalık Buğday Hatlarında Çimlenme Safhasında Kurağa ve Tuza Dayanıklılığın Değerlendirilmesi Özet: Azerbaycan çeşidlerinden seçilmiş 17 makaranlik buğday hattından uyum yeteneği ve kararlılık parametrelerine göre kurağa ve tuza dayanıklılığı incelendi. Buğday örnekleri su, tuz ve sıcaklık gerimi altında ve normal ortamda çimlendirildi. Seçilen hatlardan Leucurum 242h93, Melanopus 63h93 ve Apulicum 317h93’ün gerilimli ortamda verimli ve kararlı oldukları ve bunların kuraga dayanıklı buğday ıslahında değerli başlangiç materyali olabileceği sonucuna verildi. Anahtar Sözcükler: Uyum yeteneği, kurağa dayanıklılık, çimlenme safhası, tuza dayanıklılık, kararlılık, gerilim ortamı. Introduction The food supply for the continuously increasing population is a major concern of Azerbaijan. The solution to the food problem largerly depends on the increase and stabilization of grain productivity and the improvement of its quality. However, a large part of the soil used for wheat cultivation has a number of factors hindering grain productivity. One such factor
