Abstract:

The State Variety Release Committee, West Bengal, approved the release of two varieties, Saraswati (CN584-311-10) and Jalaprabha for deepwater ecosystems (50-100 cm) in June 1996. Saraswati is a pedigree selection from the cross Pankaj/Patnai 23, done at RRS. It was evaluated as IET11271 in national trials during 1989-94 (Table 1). The pooled average yield across 36 locations was 50% more than national check Utkal Prabha. In national testing, it ranked fourth in the 1989 preliminary variety trial, eighth in the 1993 advanced variety trial-semideep water, and second in the 1994 advanced variety trial-semideep water, tested over 13 locations. The variety’s mean yield was 2.7 t ha-1 with yield potential of 4.6 t ha-1. The All-India Rice Workshop suggested it for use in the deepwater areas of Assam, West Bengal, Andhra Pradesh, Uttar Pradesh, and Orissa.
