Fourteen rice hybrids were grown in the two successive seasons 2020 and 2021 in Kafr El-Sheikh, Egypt, at the Experimental Farm of Rice Research and Training Center to evaluate the presence of variation for investigated traits and to estimate correlations for the studied traits with the grain yield. Every analyzed trait revealed substantial variations between hybrids, indicating a wide range of genetic variability controlling the studied traits. Grain yield (t ha^-1) and 100-grain weight attributes with IR69625A×GZ6296, IR58025A×GZ6296 and G46A×GZ6296 hybrids achieved the highest estimated values and the hybrids IR70368A×PR78 and Pusa13A×Giza181 in in the grain yield only. Five hybrids showed surpass over standard check variety, EHR1 for grain yield and some other traits. A strong positive correlation and regression was found between grain yield (t ha^-1) and the following variables: panicle length, number of spikelets panicle^-1, harvest index and biological yield (t ha^-1) and it can be dependent on these trait to select the best genotypes in breeding program to improve the grain yield.
