TAILIEUCHUNG - Characterization for drought resistance at early stages of wheat genotypes based on survival, coleoptile length, and seedling vigor

In order to develop genotypes having a stable higher yield, it is necessary to characterize genetic resources based on drought adaptation, determine the suitable genotypes, and use them in breeding programs. This study was carried out in greenhouses, plant growth chambers, and research farms of the Faculty of Agriculture at Atatürk University. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2014) 38: 824-837 © TÜBİTAK doi: Characterization for drought resistance at early stages of wheat genotypes based on survival, coleoptile length, and seedling vigor 1, 2 1 1 1 3 Ali ÖZTÜRK *, Sinan BAYRAM , Kamil HALİLOĞLU , Murat AYDIN , Özcan ÇAĞLAR , Sancar BULUT 1 Department of Field Crops, Faculty of Agriculture, Atatürk University, Erzurum, Turkey 2 GAP International Agricultural Research and Training Center, Diyarbakır, Turkey 3 Department of Field Crops, Faculty of Agriculture, Erciyes University, Kayseri, Turkey Received: Accepted: Published Online: Printed: Abstract: In order to develop genotypes having a stable higher yield, it is necessary to characterize genetic resources based on drought adaptation, determine the suitable genotypes, and use them in breeding programs. This study was carried out in greenhouses, plant growth chambers, and research farms of the Faculty of Agriculture at Atatürk University. A total of 64 certified and local bread wheat genotypes were used to test survival after drought, coleoptile length, and seedling vigor. There were significant differences with respect to the selection parameters in this study. Seedling survival ranged from to and coleoptile lengths were 39–74 mm. Leaf width and specific leaf area were – mm and – cm2/g, respectively. Genotypes Lancer, Kıraç 66, Gerek 79, Mızrak, Harmankaya 99, Alparslan, Dağdaş 94, and Doğu 88 had stable high seedling survival rates and were tolerant to early drought with respect to seedling survival after drought. Local genotypes and old cultivars had higher coleoptile length compared to modern cultivars. Genotypes Ak Buğday, Tir, Lancer, Sert Buğday, and Conkesme, having long coleoptiles, could be used as genitors for the breeding of new genotypes with short .
