Abstract

In order to locate the genes controlling drought resistance and screening quantitative indices of drought resistance in WHEAT, substitution line series of cheyne (donor) jnto the genetic background of chinese spring (recipient) were tested in a randomized completely block design with three replications under two irrigated and rainfed conditions in the research field of faculty of agriculture, Razi university of Kermanshah. Based on the potential (Yp) and stress (Ys) yield, quantitative criteria of drought resistance such as: mean productivity (MP), tolerance index (TOL), geometric mean productivity (GMP), harmonic mean (HAR), stress susceptibility index (SSI) and STRESS TOLERANCE INDEX (STI) were calculated. The results of analysis of variance exhibited high significant differences among the lines for yield and yield components, indicating the presence of genetic variation and possibility of determination of the genes controlling these traits on the related chromosomes. The results of mean comparison showed that most of the genes controlling yield and yield components in the rainfed conditions are located on the chromosomes 4A, 7A, 20, 40, 50 and 6D. The results of correlation analysis between indices, potential and stress yield showed that the most suitable criteria for screening substitution lines were MP, GMP and STI. Evaluation of three dimensional plot indicated that most of the genes controlling MP, GMP and ST are located on chromosomes 7A, 1B, 25, 40 4-and 60 They can be used for improvement of drought tolerance in WHEAT MULTIVARIATE BIPLOT resulted from principap component analysis showed that most of the genes controlling quantitative criteria of drought tolerance are located on chromosomes 7A, 1B, 20, 40 and 60 supporting the same results obtained from 3-0imentional plot. To determine the genetic distance 1 and to group the substitution lines, cluster analysis showed that the substitution lines 7A, 40, 6D and chaynne were in one group supporting the results of 3-0 and biplot.
