Abstract: Chickpea (Cicer arietinum L.) is the 2ndlargest grain-legume cropin the world and is an important rabi pulse crop of Indo Gangetic Plain. India ranks first in chickpea production in the world followed by Australia, Myanmar and Pakistan. It is one of the major pulse crops in Bihar. The present investigation was undertaken using forty genotypes of desi chickpea sown in a randomized block design with three replications at the Pulse research model Bhitti farm of Bihar Agricultural University, Sabour (Bhagalpur) during Rabi, 2018-19 to determine the contribution of six morphological traits to the total variability in desi chickpea using Principal component analysis. In the present investigation PCA was performed for six quantitative traits of chickpea. All the 3PCs exhibited more than 1.0 Eigen value and showed about 91.59% variability. Therefore, these PCs were given due important for the further explanation. The PC1 showed 59.61% variability among traits, while PC II, and PC III exhibited 24.76% and 7.13% variability respectively. PC1 contributed 59.61% of the total variation and correlated with days to 50% flowering, grain yield per plot and number of pods per plant while PC2 explained an additional 24.76% of the total variation and dominated by days to 50% flowering, 100-seed weight, days to maturity and grain yield per plot. Since, a total of 84.37% of the total variation was contributed by PC1 and PC2, therefore, these two principal components can be allowed for simultaneous selection of yield contributing traits in desi chickpea. Genotype commonly found in more PC, were BLBG3, BRC-6, BLBG4, DC17-111, PBC546-18 and Sabour chana-1. 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 and these genotypes can be considered an ideotype breeding material for selection of traits viz. more total number of seed per plant and 100-seed weight further utilization in precise breeding programme.
