بررسی ارزیابی لاینهای نخود تیپ کابلی در شرایط تنش و بدون تنش خشکی ‭(07-CIDTN)‬

In order to evaluation and study the response of different chickpea genotypes to drought stress and determination of drought resistance genotypes and with high seed yield, this experiment was conducted with 41 Kabouli type chickpea genotypes including of susceptible check (ILC 3279). The experiment was performed in a RCB design with two replications under stress ( rained ) and non-stress ( irrigated ) conditions during 2006-07 and 2008-09 cropping season in Maragheh agricultural research station. In order to evaluate of chickpea genotypes for drought stress, stress susceptibility index (SSI), stress tolerance index (STI), geometric mean productivity (GMP), tolerance index (TOL), mean productivity (MP) and harmonic mean (HARM) were calculated. The results of experiment showed that in rained and irrigated conditions the highest seed yield related to FLIP 02-70C (with 1268 Kg/ha) and FLIP 87-59C (with 2112 Kg/ha) genotypes respectively. Evaluation of genotypes for stress tolerance indices showed that FLIP 87-59C, FLIP 02-69C, FLIP 02-70C and FLIP 02-48C had high indices for GMP, STI, MP and HARM and were identified as drought resistant genotypes. The phenotypic correlation of MP, GMP, STI and HARM with seed yield in both stress and non-stress conditions were significant. These criteria were recommended as desirable indices for determination of resistant chickpea genotypes.
