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**).
