Introduction of New Rice Variety

Rice is a second important crop at Iran and its cooking and eating quality plays important role for consumers. In order to improve yield and quality, a set of crosses among Amol3 and Sepidrood made with Dom­­­Siah Mashhad and Sange Jo. The F1 was back crossed with local varieties as donor parents for two successive generations (BC2) and then selfed upto five generations (BC2F5). 13 promising lines with higher yield and quality were selected. The selected lines including three checks Neda, Sepidrood and Sang Tarom planted in Randomized Complete Block Design with three replications and their yield quality test were done. Some of important characteristics of qualitative and quantitative were measurement. Line DN-33-18 accompand with quality check Sang Tarom and located in the fourth class. This Line regarding to the yield and early maturity indicated better performance than Sange Tarom (check variety). This line with 119cm height, 123 days to maturity and good physicochemical properties almost similar to the local good quality varieties, but 6.65 tons/hectare, while the average yield of local varieties is shown around 3.5-4 tons/hectare.
