 ABSTRACT

In groundnut, correlation and path coefficient analysis was carried out to identify the suitable selection indices in F3 generation of nine crosses viz., TLG 45 x ICGV-05155, JL – 501 x KDG-128, K-1641 x ALR-3, SG-99 x R-8808, ALG-234 x ICGV-00350, AG-24 x ICGV-6110,  JSSP-LS-58 x CS-19, TPG-41 x GG-16 and  J-89 x  ISK-I-16-13. Correlation analysis revealed that the traits viz., pod yield per plant had positive and highly significant correlation with plant height, number of matured pods per plant, number of immature pods per plant, kernel yield per plant and harvest index. These characters can be considered as a selection criteria for higher yield as they were mutually and directly associated with pod yield per plant. Out of thirteen characters studied, kernel yield per plant and harvest index (%) exerted maximum positive direct effect on pod yield per plant. Indirect effect of harvest index through kernel yield per plant were high. Therefore, number of matured pods per plant, kernel yield per plant and harvest index should be considered as selection criteria for improving pod yield per plant in groundnut.

Keywords: Groundnut, Correlation, Path coefficient analysis and Yield.
