ABSTRACT

A field experiment was carried out in Iraq, during the season 2014, in order to evaluate the performance of different ten genotypes of bread rice under irrigated field conditions, according to the design of randomized complete block with three replications (5 var × 2 sites × 3 rep). The results indicated the existence of genetic variability, in a significant manner (at the level 5%). Responses of the studied genotypes to the conditions of the field for all of the traits are such as Plant height (cm), Panicle length (cm), Number of grains per plant, 1000-grains weight (g), Number of tillers per plant, Number of productive tillers per plant and grain yield (g·m^﹣2). The site Al-Mishkab was lower in Grain yield than the site Dhi-Qar. The general mean over locations revealed that Yasmeen was the best with the highest grain yield (71.2 g·m^﹣2) followed by Mishkab (641.3 g·m^﹣2). The study showed the importance of the Panicle Length due to its positive and high significant correlation with the grain yield (0.544^**), so it can be used as indicator of suitable selection for the development of high-yielding genotypes. Results also showed that correlation between grain yield and plant height was negative and significant (﹣0.830^**).
