Jatropha (Jatropha curcas L.), commonly known as Ratanjyot is widely distributed in the world. In recent years it has been in news in global market owing to the utilization of its seed oil in biodiesel production. In view of its industrial importance twenty Jatropha accessions collected from different locations of U.P. were analyzed for various biometrical, physical and biochemical characteristics of seed. As regards biometrical parameter, the accessions K9 recorded largest seed (18.14mm) as well as highest seed length/breadth ratio (1.15). These were also identified as bolder seed accessions as they recorded highest seed index of 64.65g/100 seed. Seed index of various Jatropha accessions illustrated a significant variability from 45.45 to 64.65 g /100seeds depicting a mean value of 56.10g per 100 seeds. Amplitude of 2.70g in respect of seed index of different accessions indicates fair scope in identifying bolder seed sources for multiplication through breeding trials. K8 was identified as boldest seed bearing accessions as it differed significantly with rest of the accessions. It was interesting to note that K7, K8, K9, K13, 14, K15, K19, K21, K22, K24 and K25 also recorded seed index of more than 56.10g/100 and can be considered as bolder seed bearing accessions
