In order to define selection criteria 434 chickpea genotypes were evaluated under rain-fed conditions during 2015-16 rabi season. Selection of genotypes and traits based on Principal Component analysis. Out of thirteen PCS’s identified first 8 PC accounted for 77.68% of the total variation. The PC1 explained 26.57 % of total variation. While PC2, PC3, PC4, PC5, PC6, PC7 and PC8 exhibited 13.58%, 8.45%, 6.54%, 5.48%, 6.03, 4.37 and 3.66% variability, respectively. Genotype IC 84037 was commonly found in PC 1, PC3, PC 6 and PC7 followed by IC 84037 in PC 1, PC 3, PC 6 and PC 7, IC 83812 in PC 1, PC 2, PC 3, and PC 7, IC 83372 in PC 1, PC 3, PC 5, and PC 7, IC83592 in PC 1, PC 4, PC 5 and PC 7, similar type of genotypes on a common principal component permitting to designate them as seed yield factors. These genotypes may further be utilized in breeding programmes for improving seed yield these genotypes can be considered an ideotype breeding material for selection of traits viz more total number of seed per plant, more effective pods per plant and high biological yield per plant and further utilization in precise breeding programme. The maximum PC value was found in genotype IC 84037 (9.79) followed by, IC 83812(8.46), EC 489919(7.70), IC 83387 (6.42), IC 83813 (6.24). This result has been suggested that these genotypes would be of practical value to chickpea breeders in identifying the genotype with desired trait for utilization in breeding program for genetic improvement.
