Yield Evaluation of Kabuli Type Chickpea Landraces in Rainfed Conditions

Chickpea is mostly cultivated as a rainfed crop in Iran and its seed filing period faces to drought, heat and high evaporation and transpiration which couses yield decrease, therefore more attempts are needed to find genotypes with high and stable yield in rainfed conditions. In the present study, twenty two Kabouli type landraces and three improved chickpea cultivars, Arman, Azad and Hashem were planted in experimental farms of Kermanshah, Kurdistan, West Azerbaijan and Lorestan research centers. The experiments were conducted in randomized complete block design with four replications for two years (2012-13). Different phonological and agronomical traits were recorded each year. Combined analysis of variance showed that genotype × environment effect was significant (P≤0.01) for traits of days to flowering, days to maturity, plant seed weight, pod number per plant, 100 seed weight and seed yield. Based on the results, difference of plant canopy height of genotype 5671 with Arman and Azad cultivars was not significant statistically. Genotype 5551 with 23, had the maximum number of pods per plant which was significandly different (P≤0.05) from Hashem, Arman and Azad check cultivars. Genotypes 5654, 6325, 5296, 5618 and 5843 had the highest values of harvest index, respectively. Stability analysis and bi-plot display of genotypes in different locations showed that genotypes 5171, 5296, 5654, 6084 and 6325 had higher seed yield with more stability than other genotypes.
