Abstract From 18 Zea mays L. inbred lines, two were chosen as drought tolerant and drought sensitive genotypes (G615w and G635y, respectively). They were evaluated along with their F1 and F2 for their relative drought tolerance for some water stress-related traits. SDS-protein profiles indicated the occurance of polymorphism patterns such as peroxidase and acid phosphatase isozymes, all of these patterns showed differential responses with respect to drought tolerance. Bulked segregant analysis revealed that RAPD markers exhibited PCR amplification products especially with primer B11 (two bands 270 bp and 500bp), which are considered as molecular markers, linked with drought tolerance. Key words: Zea mays, drought tolerance, water stress-related traits, SDS-PAGE, peroxidase isozymes, acid phosphatase isozymes, PCR, RAPD, bulked segregant analysis (BSA). |
