Horsegram (Macrotyloma uniflorum) is a potential legume crop consumed as pulse and used as fodder in different parts of the world. The present investigation was carried out to study the correlation and path analysis among the various genotypes of horsegram with and without treatment of Rhizobium culture. Ninety six diverse lines were sown in two different conditions (E1 and E2) in randomized block design. The data revealed that there was significant differences for these traits among the genotypes after treatment of Rhizobium culture as compared to without treated experiment. The PCV was found to be slightly higher than GCV in all traits indicating the importance of greater genetic variability with less influence of environment. Estimates of heritability and genetic advance were higher for all the traits in E2; indicating the role of Rhizobium in the transmission of genotypes. Estimates of correlation coefficients at genotypic, phenotypic and environmental level indicates significant positive relationship of nodule, root fresh weight and root volume with shoot fresh weight in both conditions. So, these finding can help in further breeding programmes to select the characters related to high biomass production using Rhizobium treatment.

Abstract


Horsegram (Macrotyloma uniflorum) is a potential legume crop consumed as pulse and used as fodder in different parts of the world. The present investigation was carried out to study the correlation and path analysis among the various genotypes of horsegram with and without treatment of Rhizobium culture. Ninety six diverse lines were sown in two different conditions (E1 and E2) in randomized block design. The data revealed that there was significant differences for these traits among the genotypes after treatment of Rhizobium culture as compared to without treated experiment. The PCV was found to be slightly higher than GCV in all traits indicating the importance of greater genetic variability with less influence of environment. Estimates of heritability and genetic advance were higher for all the traits in E2; indicating the role of Rhizobium in the transmission of genotypes. Estimates of correlation coefficients at genotypic, phenotypic and environmental level indicates significant positive relationship of nodule, root fresh weight and root volume with shoot fresh weight in both conditions. So, these finding can help in further breeding programmes to select the characters related to high biomass production using Rhizobium treatment.
