In: Mansoura University Journal of Agricultural chemistry and biotechnology 2011.v.2(11)Summary: Line x tester experiment was conducted to evaluate the performance of 25 F, hybrids along with ten parents in rice at Rice Research and Training Center (RRTC), Sakha, Kafr EI-Sheikh, Egypt during 2007 and 2008 growing seasons to estimate the percentage of heterosis and heterobeltiosis among F, hybrids developed from five lines and five testers of rice. Genotypic mean squares for all studied traits were highly significant and had genetic variability for these traits. Heterosis and heterobeltiosis were estimated for number of days to maturing,
