Abstract: Sunnhemp (Crotalaria juncea L.) is extensively cultivated for fibre or green manure, or intercrop/cover crop and leaves are fed as a high protein supplement to other poorer feeds. Due to several biodiversified utilization of this crop, there is a requirement to develop some location specific, disease resistant, high yielding and better quality fibre variety of Sunnhemp. Since long the farmers are engaged to cultivate the traditional few varieties of sunnhemp that have very low yielding and inferior quality fibre. Keeping all of the above, an attempt has been made to develop such type of variety that contribute highly productive and better quality fibre of sunnhemp with the support of All India Network Project on Jute & Allied Fibres (AINP on JAF) by taking several multilocational evaluation trials. So, conclusion may be drawn that the variety JRJ 610 (Prankur) have been developed from five selected individual parents’ viz. SUIN-01, SUIN-055, SUIN-056, K-12(B) and K-12 (Y) involving series of crosses followed by random mating in isolation and mass selection and this variety is resistant to major diseases and pest, highly productive and giving better tenacity fibre.
