COMBINING ABILITY ANALYSIS FOR YIELD AND ITS COMPONENT CHARACTERS IN RICE
This investigation was carried out at the Farm of the Rice Research & Training Center, Sakha Kafr El-Sheikh, Egypt during 2012 and 2013 rice growing seasons to estimate the general combining ability (GCA) and specific combining ability (SCA) effects for yield and its component characters at the two years and their combined data. The characters were panicles plant-1, filled grains panicle-1, panicle weight, sterility %, 100-grain weight and grain yield plant-1. The results revealed that the parents Giza 178, , IR 65600-38-1-2 and the crosses Giza 178 x BG-35-2, Giza 178 x IET1444, Giza 178 x IR 6560-38-1-2 and BG35-2 x IET 1444 were found to have the most desirable mean values for yield and its components characters under the two years and their combined data. Genotypes, parents and the resultant crosses mean squares were found to be highly significant for all the characters studied. Highly significant positive GCA effects were found from the parents Giza 178, IET 1444 and IR 65600-38-1-2 for filled grain/panicle-1, BG35-2, Nishihomare , RD-25 and IR 65600-38-1-2 for 100-grain weight; Giza 178, IET 1444 and IR 65600-38-1-2 for grain yield plant-1. the most pronounced crosses over the two years and their combined data were Giza 178 x RD-25, Giza 178 x IR 65600-38-1-2 and RD-25 x IR 65600-38-1-2 for grain yield plant-1; Giza 178 x Nishihomare ,Giza178 x IR65600-38-1-2 and RD-25 x IET1444 for panicle weight; Giza 178 x IR65600-38-1-2 RD-25 x IET1444 and IET1444 x Nishihomare for the number of panicles plant-1
