Abstract:

Correlation and path analysis was carried with 40 genotypes of groundnut for yield and its component traits. Character association analysis revealed significant and positive association of kernel yield per plant, harvest index, plant height, number of primary branches per plant, seed sulphur uptake, seed iron uptake, seed sulphur (%) at maturity, seed calcium uptake, number of pods per plant, seed iron (ppm) at maturity, leaf iron (ppm) at 60 DAS and shelling percent with pod yield per plant in groundnut. Path coefficient analysis indicated that kernel yield per plant exerted the highest positive direct effect on pod yield per plant. It was also revealed that plant height, days to maturity, seed calcium uptake and seed iron uptake contributed indirectly to pod yield per plant through kernel yield per plant. These characters also exhibited highly significant and desirable association with pod yield and among themselves. This information could be utilised in formulating a sound selection criterion in groundnut breeding programmes for genetic improvement of high yield potential genotypes with high nutrient uptake ability.
