Improving Grain Yield in Rice (Oryza Sativa L.) by Estimation of Heterosis, G...
The recent approach for rice production includes the improvement of yield is necessary to cater for consumer demand. Therefore, a field experiment (diallel analysis) was conducted and Training Center, Egypt during 2014 and 2015growing season to estimate combining ability, heterosis and genetic parameters in ricefor improving the yield. Th and Sakha105 were recorded highest mean values for most traits. The crosses (Giza177 × Sakha106, Sakha101 × Sakha104 and Sakha101 × Gz7576-10-3-2-1) were recorded highest mean values for grain yield plant-1.Sakha106 and Sakha104 recorded the highest mean values for flag leaf area. evident from the result, a positive correlation was observed between flag leaf area and grain yield as well as, the results were recorded positively correlation coefficient between n to heading, number of filled grains panicle-1 and 1000-grain weight. cross Sakha 101/Sakha 104, Sakha 104/Sakha 106, Sakha 105/BL1 and Sakha 106/BL1 were identified as themost promising cross for developing high yielding rice varieties and could be further benefits to isolate superior transgressive segregants for breeding programs

Heterosis, Combining ability and Phenotypic Correlation for Some Economic Tra...
This investigation was carried out to study heterosis , combining ability and phenotypic correlation in a diallel mating design among 6 Egyptian rice genotypes (excluding reciprocals),including 3 varieties ( Sakha 101, Sakha 104 and Sakha 105),and 3 promising lines (Gz6903, Gz7576 and Gz8479). An experiment was conducted at the research Farm of Rice Research and Training Center (RRTC), Sakha, Kafr EL-sheikh, Egypt during 2013 growing season and designed in a randomize complete block with three replications. Data were recorded on nine traits; days to maturity, chlorophyll content, flag leaf area, plant height, number of panicles / plant, panicle fertility (%), Panicle weight ,1000-grain weight and grain. The results revealed that, the genotypes were highly significant different in all studied characters. The cross (Sakha 101 × GZ6903) showed positive and significant heterosis for mid and better parents for most studied traits. The parent (Sakha 101) was good general combiner for most studied traits. The cross (Sakha 101 × GZ6903) showed positive and highly significant for specific combining ability effects for grain yield and its components.Grain yield was significantly and positively correlated with days to maturity, chlorophyll content, plant height, number of panicles/plant and panicle weight .On the contrary, plant height had significant negative association with days to maturity.
