Abstract Five faba bean (Vicia faba L.) genotypes which have different response to salt and drought stress and are adapted to cultivation in Egyptian agricultural conditions were used. The used genetic materials were NBL (Mar.3) , NBL-5 and L3 chosen through faba bean breeding program of Plant Genetic Resources Department, Desert Research Center, Cairo Egypt; Nubariya-1 and Misr-1 from Agricultural Research Center. Two pot experiments were carried out under three levels of each drought and salinity in the green house in the experimental garden of the Botany Department, Faculty of Women, Ain Shams University. Chromosomal studies are based on visible characteristics of the chromosomes. According to the parameter, genotype (G.4) may be considered as less evolved one. But, genotype (G.1) may be considered the more evolved one. Three morphological traits (leaf area, stem height and Number of branches) were measured, data showed significant differences that increase in stress had resulted in a reduction in total leaf area, stem height and number of branches. Genotype (G.1) recorded the highest values of leaf area under both two stress conditions. Also, Genotype (G.2) recorded the highest value under the levels of drought and salt stress. Where, genotype (G.2) recorded the highest number of branches. But less number of branches/plant recorded in genotype (G.4) under drought stress and in genotype (G.5) under salt stress. |
