Abstract

Since 1990s, development of wilt resistant and high yielding hybrids has played an important role in increasing
the productivity of castor from around 320 kg/ha to 1700 kg/ha. Eleven elite monoecious lines having wilt resistance were developed by hybridization using five germplasm and seven elite monoecious lines. The elite lines viz., ICS- 303, ICS-304, ICS-315 and ICS-318 had better yield traits like spike length, seed weight and seed yield per plant. ICS-320 and ICS-321 derived from 48-1 and RG-2991 had the highest oil content (>50%) than the checks 48-1 and DCS-107. These elite lines will help in development of wilt resistant and high yielding hybrids and varieties in castor.
