Abstract

In order to group the candidate genotypes tolerant to chickpea drought in different planting dates, an experiment was conducted in the form of split plots in the form of randomized complete blocks design, in four replications in the research farm of the Ferdowsi University of Mashhad, Faculty of Agriculture in the crop year 2017-2018. The experimental treatments included planting dates (March 14 and April 24) as main factors and chickpea genotypes (MCC696, MCC552, MCC537, MCC427, MCC352 and MCC80) and two cultivars Jam and Samin as secondary factors. The results showed that the genotypes in the first planting date compared to the second planting date were superior in all traits. The highest number of days to maturity (103 days) and seed yield (1.06 kg/m2) were obtained in 696MCC genotype and height (34 cm) and biological yield (2.64 kg/m2) in 537MCC genotype. The number of pods in the 352MCC genotype plant (34 pods) was the highest. In order to group the genotypes based on similarity, they were divided into four clusters on the first planting date and three clusters on the second planting date. PCA results showed that PC1 and PC2 (69.1%) accounted for the total variance of the data on the first planting date and (63.3%) on the second planting date. In general, the results showed that the best planting date for chickpea cultivation in low irrigation conditions of Mashhad was on March 14 and the best genotypes for cultivation were 537MCC and 696MCC.
