Provision of superior genotypes of Jatropha Curcas for biodiesel production : integrating morphology and yield variation with DNA-based marker



Selection and grouping based on the yield parameter specifically number of fruits per bunch of Jatropha curcas which also relates to the weight of individual fruits and the morphological performances related to shape and colour of leaves and petioles of 60 accesion numbers has been made. Four groups related fruit yield were identifield i.e. A (>4), B (>3), C (>2), D (0-1) fruits per bunch while 5 groups consisting of 3 of petiole, 1 of mature leaves, 2 of young leaves and 2 of shoots colours. The size of leaves could not be differentiated as mostly were similar. The correlation between fruit yield and RAPD marker was assessed by screening 17 random 10-mers primers which resulted three primers i.e. OPB-10 and OPH-01 could be amplifield. Altought further study and confirmation are needed, the results indicated that several accessions possessed different banding patterns which might be a potential marker related to fruit yield and in the future this would also be used for assessing that of oil content. The oil content was around 22% and 37.5% using pressing machine and chemically extracted, respectively. J. curcas clustering based on morphological character indicated that there was a correlation between fruit yield and growth response. The confirmed genotype superiority would support Jatropha’s based especially bio oil industries to increase production cost efficiency through the use of improved genotypes and appropriate cultivation suitable for each condition area.
