ABSTRACT

Ninety genotypes of soybean including five checks were evaluated to know the correlation between yield and yield attributing traits in soybean during kharif 2014. Grain yield was found to be positively and highly significantly associated with number of pods per plant, seeds per pod, 100 seed weight, both at genotypic and phenotypic levels. Protein % showed positive and significant association with number of pods per plant while oil content showed negative and significant association with plant height at both genotypic and phenotypic level.

Key Words: Genotypic correlation coefficient, Phenotypic correlation coefficient, Soybean
