In order to evaluate yield and yield components properties of cold-tolerant chickpea under winter sowing and complementary irrigation conditions, two experiments in the context of partial balanced block design with 81 chickpea genotypes and three replications were carried out. Complementary irrigation was performed during growing season including irrigation immediately after sowing, 20 days after the first irrigation and at early phase of flowering. After winter cold, survival percentage of the chickpea genotypes was calculated and total precipitation rate from sowing to harvesting was 267 mm. Moreover, properties of grain yield components (survival percentage, pod number per plant, the number of grains per pod and weight of 1000 grains), grain yield, biological yield and harvest indices of the genotypes were measured and recorded. Based on the results, the difference between the genotypes was significant for all the measured properties. Under complementary irrigation, 40 percent of the genotypes showed winter survival rate higher than 76 percent and grain yield in 52 percent of the genotypes was higher than 100gr/m2. Under winter sowing condition, grain yield in 32 percent of the samples was higher than 40gr/m2. Finally, under winter sowing and complementary irrigation regime, the genotypes ‘MCC333’, ‘MCC186’, ‘MCC803’ and ‘MCC743’ possessing yield over 600 kg/ha were determined as the superior genotypes.

In order to selection of superior cold tolerant barley genotypes for cold regions of Esfahan province, this study was conducted with nine barley varieties/lines in Fereidan area, and in two successive years (2002-2004). The research was carried out in on-farm pattern experiment and in a CRB design. Results showed that grain yield and some of yield components affected by year, variety and their interactions, significantly. Positive and significant correlation observed between grain yields and numbers of spikes per square meter. Changes of numbers of spikes per square meter were main cause of grain yield variations. Grain yields correlated with thousand kernel weight, negatively and significantly. The grain yield of CB-74-2 barley line was the highest in all years, significantly. Also, the grain yield of IFN-12 and IFN-13 barley lines, selected from Esfahan province’s local varieties, were significantly higher than check variety (Makooii).
