Abstract

Abstract
In order to investigate of phenological and morphological characteristics, yield components and yield of cold tolerant chickpea genotypes in fall sowing, 9 cold tolerant chickpea genotypes and Karaj 12-60-31 as a control were evaluated in Experimental Field of College of Agriculture, Ferdowsi University of Mashhad in 2006-2007. The experiment was carried out based on randomized complete block design with four replications. The planting date was 25 October and three times of irrigation was done as supplementary irrigation at planting stage, 20 days after that and at flowering stage. The control was ruined at seedling stage due to the hard cold. Based on the results, the differences among the genotypes for all of measured traits including growth duration, plant height, number and length of branches, yield components (pod number per plant, seed number per pod and 100 seeds weight), seed yield and biological yield were significant (P≥0.05). There were positive and significant correlations between seed yield and vegetative (r=0.71**) and reproductive (r=0.68**) periods. MCC291, MCC349 and MCC207 produced the highest seed yield with 231, 229 and 217 g.m-2, respectively. Totally, it appears that some of genotypes have appropriate yield potential for fall sowing under supplementary irrigation at Mashhad.
