Abstract:
The present investigation was carried out at Medicinal Plant Research and Development Centre of the G.B. Pant University of Agriculture and Technology, Pantnagar during the year 2011-14. The forty six open pollinated genotypes of Jatropha curcas collected from various parts of the country and planted in Randomized Block Design. All the genotypes showed sufficient genetic variability. The PCV and GCV indicated that the values of PCV were higher than of GCV, but the difference was very closer between these two estimates for all parameters. The highest heritability observed for seed yield per plant and seed yield per ha and total number of branches per plant, days to flower initiation, collar diameter and pant height parameter. High estimates of genetic advance recorded for seed yield per ha, plant height and total number of branches per plant. Seed yield per ha showed highly significant positive correlation with total no. of branches, collar diameter and seed index. The diverse genotypes having high heritability, genetic advance and positive correlation of phenotypic and genotypic correlation would be helpful in selection and improvement of genetic population in breeding program.
