Abstract:

In India, rice is predominantly grown on 1.4 million ha of traditional and 0.9 million ha of nontraditional areas in the state of Maharashtra. Average productivity is 1.7 t ha-1. A total of 53 high-yielding rice varieties (HYVs) have been released for commercial cultivation in the state for various agroecological conditions. The productivity of rice nevertheless remained stagnant during the last decade. The adoption of rice hybrids, along with proper crop management practices, is certainly an alternative for increasing productivity in the state. The RARS in Karjat, District Raigad, has identified and released the first rice hybrid, Sahyadri, for commercial cultivation. It has medium-late growth duration and a high yield potential, (6.5-7.5 t ha-1). The area under hybrid rice is increasing gradually in the state, but nearly 60% is planted to early-duration rice varieties. Efforts were therefore made to develop suitable early-duration rice hybrids with desirable characteristics to increase rice productivity.
