Hybrid rice has been a successful and widely adopted technology that has increased rice production in China since early 80’s of the last century. But in India inspite of development of several successful hybrids the technology has not been widely adopted and is cultivated in select regions only. West Bengal is the largest producer of rice. But hybrid rice is cultivated in a very limited area. There is urgent need to adopt the hybrid rice technology to enhance the production level to meet the ever increasing food demand. Hybrid rice seed yield of the popular hybrids is reported to be very low. So, there is need for refinement of hybrid rice seed production technology to enhance the production to a level of 2-2.5 t ha-1 from the present level 1-1.5 t ha-1. On this back ground the present study was conducted to fine tune the seed production technology of the popular hybrid rice, KRH 2 with respect to the Gangetic New Alluvial Zone of West Bengal to determine the exact seeding interval of the parental lines and to standardize the dose of GA3 in both kharif and boro seasons. The experimental materials included the parental lines of KRH 2 i.e. CMS line-IR-58025A and restorer line KMR 3. The experiment was conducted at the Teaching Farm, Monduri, Bidhan Chandra Krishi Vishwavidyalaya, Nadia, West Bengal during kharif 2012, boro 2012-13, kharif 2013 and boro 2013-14.
