Correlation and path coefficient analyses in ratanjot (Jatropha curcas L)

An experiment was conducted with forty six genotypes to study character association and path coefficient analyses in J. curcas L. The trait number of fruit clusters/plant (0.681**,0.905**) along with number of fruit/cluster (0.331*, 0.495**) and dry fruit yield/plant(0.978**,0.995**) had significant correlation with seed yield both at phenotypic and genotypic levels. Only dry fruit yield/plant had relatively large positive and direct influence (0.980, 1.3672) on seed yield both at genotypic and phenotypic levels. The other variables viz., number of fruit clusters/plant(0.6918, 1.2509), number of fruits/cluster (0.3420, 0.7109) and 100-seed weight (0.2822,0.5865) exerted their major effect on seed yield indirectly through dry fruit yield/plant, atphenotypic as well as genotypic levels respectively.
