After wheat, rice is the second most important cereal grown in Iran that improvement of its economical characteristics always has important role in the rice breeding programs. In order to estimate the genetic parameters and identify salt-tolerant varieties and hybrids in seedling stage, seven female parents (Shah-pasand, Gharib, Tarom Mahalli, Ahlami Tarom, Hashemi and Dom Sepid) and four male ...

Seven Iranian and foreign cultivars of rice were crossed in a half-diallel. Parents with F2-generations were transplanted in a randomized complete blocks design with 3 replications and evaluated for length to breath ratio of paddy and brown rice, head rice and crust, grain yield, percent of head rice and broken rice, amylose content, gelatinization temperature and gel consistency. The ANOVA tab...
