Abstract
A new wheat variety resistant to cereal cyst nematode (CCN), CCNRV 1 (Raj Molya Rodhak 1), was developed from two genetically diverse cultivars in a single cross (J 24/AUS 15854). This variety exhibited a higher level of productivity in both CCN-infested and normal soils, with increases in the grain and straw yields of 78.7% and 60.1%, respectively, over Raj 3077 in infested soils. It also gave 19.0% higher yield than local varieties under timely-sown irrigated conditions in normal soils. It possesses superior grain quality along with other desirable agronomic traits. Genetically it carries a dominant gene for CCN resistance. It is a robust and reliable wheat variety that offers a high degree of resistance against nematodes in warmer areas of Rajasthan, India. It was recommended for timely-sown, irrigated conditions in CCN-infested areas of Rajasthan by the State Seed Sub-Committee on Crop Standards, Notification and Release of Varieties in September 2002. It is envisaged that this variety will help to boost wheat production and alleviate the socioeconomic problems of subsistent Indian farmers in CCN-infested areas
