Abstract

In this research a total of 352 local wheat accessions of National Plant Gene-Bank of Iran were evaluated in SALT STRESS condition. The accessions were received from 24 countries and were studied in research field of Ardakan station in Yazd province, Iran with soil EC of 10 ds/m. The seeds of the accessions were planted in an augmented statistical design with three check cultivars of Kavir, Yazd and Mahooti and irrigated by EC=12 ds/m water. Twelve agro morphological traits were recorded according to IPGRI descriptor. The result showed that the highest coefficient of variation (31.27) belonged to number of tillers. Five traits as independent variables including number of seeds per spikes, 100-seed weight, number of florlets per spikelets, number of stem nodes and plant height entered the stepwise regression model and justified 98% of variation in seed weight of five spikes. Based on favorable values of principal components and comparison with check cultivars, 14 accessions were identified as superior. The relationship among the origin of the accessions was investigated by cluster analysis and the countries were located in two groups. The total results of this research indicated the existence of suitable genetic diversity in the studied traits. Besides, bread wheat GERMPLASM of National Plant Gene Bank of Iran proved to be a rich genetic resource to be exploited for salt TOLERANCE.
