Abstract:
The present investigation was taken to estimate the characters correlation coefficient along with direction and path coefficient analysis with the help of raising 20 variant varieties of field pea at Nidharia farm of S.M.M. Town Post Graduate College, Ballia during Rabi season 2017-18. The field experiment was conducted with maintaining principles of experimental designs under timely sown conditions in complete randomized block design with three replications. The data were recorded on eleven characters including yield for estimates of phenotypic and genotypic coefficient of variation. Phenotypic coefficient of variation (PCV) values were slightly higher than corresponding genotypic coefficients of variation (GCV) for all attributes revealing small effects of environment in character expression process. Results of correlation coefficients revealed that grain yield had significant and positive associations with pod length (0.580), biological yield per plant (0.700) and test weight (0.484), while, it had a negative but significant associationship with branches per plant (-0.411). The data for direct and indirect effects were estimated through path coefficient analysis and observed that biological yield per plant (1.303) had highest positive direct effect on seed yield followed by harvest index (0.821), revealing that these characters might be useful during breeding programmes as effective selection attributes for yield improvement in pea.
