A paddy variety GNR-3 suitable for value addition
In Gujarat, rice occupies about 5 % of the gross cropped area and is being grown on about 6.5 to 7.0 lakh hectares, of which about 50-60 % is under low land (transplanted) and remaining 40-45 % under upland rice (drilled) situation. Gurjari is the most popular rice variety in low land. As it is suitable for pohuva preparation, it fetches higher price in south Gujarat. South Gujarat in general and Navsari in particular has the maximum number of pohuva mills. Particularly from Navsari, 500 tones of pohuva are being transported daily to other parts of the country. In view of superior quality of pohuva being produced in Navsari area, it fetches premium price in national market. Because of its suitability of Gurjari for pohuva making, its demand is tremendous and there are ample chances to increase the demand for Gurjari type rice variety. Hence, it is necessary to develop such rice variety which is suitable for pohuva preparation of superior quality, so that the farmers can have a viable option for Gurjari variety. This will also lead to multi-culture combination of rice varieties. In this context, the proposed variety GNR-3 (Gujarat Navsari Rice-3) derived from a cross IR-28 x GR-4 was bulked from the advanced generation in the year 2007, which is similar to Gurjari and appear suitable for pohuva making. The proposed genotype was evaluated in various categories of trial from 2007 to 2011 in South and Middle Gujarat. The genotype performed very well under South Gujarat condition and it exhibited 19.4% grain yield superiority over Gurjari under irrigated transplanted condition and 29.3% grain yield advantage over GR-7 under rainfed transplanted condition. With respect to pest and diseases, it was found almost similar to Gurjari. The opinion from the pohuva mill owners was obtained for judging its suitability for preparing pohuva. As per their opinion, this genotype was found to be suitable for pohuva preparation and specially released as a suitable alternative to Gurjari.
