Abstract: (126 Views)

Legumes are common crops in arid and semi-arid regions. This study was conducted to investigate three levels of salinity stress on 18 lentil cultivars in the greenhouse and laboratories of Mohaghegh Ardabili University in 2016-2016 in a factorial manner in the form of a randomized complete block design with three replications. The results of comparing average lentil genotypes were done with Duncan's method at the five percent probability level. Correlation was done in separate stress levels. The dendrogram of cluster analysis divided the genotypes into three groups in control and 60 mM conditions and two in 120 mM conditions. Genotypes 7 and 5 were in the top group in all groupings. The relationship between ISSR molecular markers and physiological traits was calculated among genotypes. All traits in three levels of salinity stress had a significant correlation with some ISSR markers. A total of 22 positive markers for physiological traits were identified at the control level, 9 positive markers at the moderate stress level, and 23 positive markers at the severe stress level. Among the 21 studied ISSR primers, the P8A11 marker had the largest number of gene loci related to the studied physiological traits.
