Abstract
Three promising lines of maize namely; GM 28, GM 31 and GM 32 were used in this study to know the genetic behavior for salinity tolerance under Egyptian conditions using half diallel and six populations analysis. Days to 50% silking, plant height, 100-kernal weight, number of kernels/row, grain yield, Na+ content, K+ content, prolinecontent, osmotic pressure and relative water content were the importance traits studied to know the reaction of salinity tolerance in maize. In addition to specific - RCR markers were used in all genotypes as index for salinity tolerance by low level of Na+ content and high levels of K+, proline and relative water contents using (RD29B, KIN2, CoR15 a and P5CSI) primers, respectively. The best genotypes were GM 31, GM 32 and the crosses GM 28 × GM 32 and GM 31 × GM 32 under normal and salinity conditions through using the traditional and new method of biotechnology
