In order to determine the genotype × environment (GE) interactions and yield stability, an experiment was conducted with 10 promising genotypes of rice and two control varieties (Shiroudi and Fajr) in four regions of Mazandaran (Amol , Babol, Sari and Tonkabon) using randomized complete blocks design with four replications during two cropping seasons (2012-2013). Analysis of variance showed sig...

Existance of genotype × environment interaction effects are constraints in evaluation and release of new cultivars. In order to evaluate new high-yielding promising lines and assess their yield stability, an experiment was conducted with ten promising genotypes of rice and two control variety (Shiroudi and Fajr) in two regions of Mazandaran (Deputy of Rice Research Institute in Amol and Ghavdas...

     Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...

Stem or black rust of wheat, caused by Puccinia graminis Pers. f. sp. tritici Eriks. and Henn (Pgt), was the most feared and devastating disease of wheat at one time worldwide. The fear from stem rust was understandable because an apparently healthy looking crop about 3 weeks prior to harvest could reduce to a black tangle of broken stems and shriveled grain by harvest. The disease has been co...
