Abstract

Groundnut is an important oilseed crop of India. Identification of genotypes having very good yield contributing traits forms an important objective in groundnut to improve the kernel yield. The present experiment was conducted to know the association of various yield characters with kernel yield in 33 genotypes of groundnut collected from different parts of the country and world. Character association analysis indicated the significant and positive association of SCMR 60 DAS, harvest index, shelling percentage, 100 kernel weight and oil content with kernel yield per plant at both genotypic and phenotypic levels whereas SCMR 50 DAS recorded positive significant association only at genotypic level. Thus, kernel yield can be improved simultaneously by improving any of these characters. Path coefficient analysis revealed that harvest index, shelling percentage and 100 kernel weight exhibited strong positive correlation and high direct effects on kernel yield per plant both at genotypic a
