Evaluation of Kabuli type chickpea under stress and non-stress conditions of Iran
Drought stress is one of the most important abiotic stresses in the world reducing grain yield of crops.Nearly 98%of chickpea area in Iran is planted in rainfed condition.In order to study the response of different chickpea genotypes to drought stress and to identify drought tolerant and high yielding genotypes,this experiment was conducted with 40 kabuli chickpea lines along-with susceptible check(ILC 3279).The experiment was performed in a RCB design with two replications under stress(rained)and non-stress drought(irrigated)conditions in three research stations(Kermanshah,Maragheh and Shirvan)in Iran during 2006-07 and 2008-09 cropping seasons.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 values(HARM)were calculated.‘FLIP 02-70C’,‘FLIP 02-48C’ and ‘FLIP 02-69C’ 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 are recommended as desirable indices for identifying resistant chickpea genotypes.
