Path Coefficient and Correlation Analysis Studies on the Variation Induced by Gamma Irradiation in M1 Generation of Chickpea (Cicer arietinum L.)

Muhammad R. Khan and Afsari S. Qureshi

Abstract:
Seeds of three chickpea genotypes having different seed coat colours viz; Noor 91 (white), Punjab 91 (brown) and C 141 (black) were treated at 40, 50 and 60 Kr separately and with gibberellic acid (GA3). Three genotypes responded differentially for path analysis and correlation coefficient studies for various traits. Plant height, number of primary and secondary branches had negative path coefficient in Noor 91 and Punjab 91 while, these were positive in C141. Pods per plant were positively contributed in the three varieties while biological yield in Noor 91 and Punjab 91. 100-seed weight and maturity days had positive direct effect on grain yield in Noor 91 and C141 while, these were negative in Punjab 91. The genotypic correlations in most of the characters were higher than the corresponding phenotypic correlations. Pods per plant had positive and highly significant correlation with grain yield in three genotypes. Number of primary branches was positively and significantly associated with grain yield in Punjab 91 and C141. Seeds per pod, harvest index were highly significantly correlated while; biological yield was significantly associated with grain yield in Noor 91 and Punjab 91. Plant height and 100-seed weight had significant and positive correlation with grain yield in Punjab 91.
