Abstract

In order to determine the best quantitive index for assessment of chickpea response to drought, a field experiment was conducted in 1996 at Experimental Station of Agricultural Research Center of Kurdistan, Iran. In this experiment 24 genotypes of desi type chickpea were sown at two sowing time and two moisture levels including, rain fed and irrigated conditions in a factorial split -plot experiment with three replications. Genotypic differences were observed for 14 recorded traits and five different drought response indices [DRI (Drought Response Index), STI (Stress Tolerance Index), TOL (Tolerance), MP (Mean Productivity) and GMP (Geometric Mean Productivity)].Their values were estimated to identify tolerance of chickpea alines to drought. CORRELATION coefficients, scatter plots and principal component analysis show that STI and MP are the best indices for drought resistance evaluations in chickpea. Using these indices, four high yielding and early maturing drought tolerant genotpes (ICCV 93032, ICCV 94008, ICCV 90033 and ICC 89204) were selected. A registered drought resistant line, ICC 4958, which produced highest seed yield, but due to its large seed size and dark yellow color, is not a desirable variety in the country. It is therefore, recommended to be used as progenitor in drought tolerance breeding programs.
