| Abstract | ||
| Several crosses have done between local rice cultivars and improved varieties in order to improve and releas high yield withing cultivars with suitable quality characteristics during lastthree decates in Iran. A hybridization breeding program with high emphasis on quality started in 1985. In that program, two groups of riice cultivar (localaromatic cultivars and high yielding improved ones) werecrossed in all possible mating systems (complete dialllel crosses). Suitable crosses were sellected and segregating generation were handled based on the pedigree method. Quality analysis of the selected sigle plant and lines were done in each generation. Finally six promisiing high yielding lines with good cooking and eating qualities were obtained from Sang Tarom and Hassan sarai with Amol 3. One of them D2-12-54, showed superiority in sense of yield and quality, comparing to others improved cultivars as well as Amol 3 and Nemat cultivars. Quality and some important agronomy characteristics of D2-12-54 (Neda c.v.) are as follows: Amylose content 26.2 percent gelatinization plant heigh 100 cm panicle length 26cm 1000 grain weight, 30gr maturity length 130 days average yield 8384 Kgha-1 resistant to blast and tollerant to stem borrer. | ||
