Abstract:
Genotypic correlation and path coefficient analysis were used to determine the effect of various traits as components of biomass yield in thirty sunnhemp [Crotalaria juncea (L.)] genotypes. The thirty sunnhemp genotypes were evaluated at research farm of department of Genetics and Plant Breeding, Navsari Agricultural University, Navsari during kharif-2017. Randomized complete block design with three replicates was used for laying out the field experiments. Path coefficient analysis indicated the high positive direct effect of dry weight of root nodules per plant, days to fifty percent flowering, leaf length, root length, C:N ratio, primary branches per plant and leaf area on fresh weight of plant. These findings suggested that emphasis should be given on these traits for selecting elite genotypes and further breeding programme. The character plant height, internodes per plant, stem diameter, root nodules per plant and fresh weight of root nodules per plant exhibited negative direct effects on fresh weight of plant.
