Analysis of combining ability in short duration rice genotypes (Oryza sativa L.)

Manish Kumar, Ravi Pratap Singh, Ramlakhan Verma and Onkar Nath Singh
Combining ability analysis of the parentage to be utilized in breeding programme is essential for substantial maximization of the genetic gain and selection of efficient breeding methodology. Altogether, 28 F1’s generated in diallele fashion (excluding reciprocals) along with parents were evaluated and analysed for combining ability of yield and 13 contributing traits. In the study, most of the yield components were governed by both additive and non-additive gene effects with dominated non-additive gene action. The additive gene action (GCA) was found substantial for 1000-grain weight. The parental genotype NDR 97 and Vandana were found good general combiners. The hybrids namely Vandana/Hazaridhan, Vandana/ Sahabhagidhan, Vandana/ Kamesh, Vandana/ Virendra, Vandana/ Sahabhagidhan, Vandana/ NDR 97, Vandana/ Shusk Samrat, Hazaridhan/ Kamesh, Hazaridhan/Virendra, Sahabhagidhan/ Virendra, Sahabhagidhan/ NDR 97, Kamesh/ Narendra-80, Kamesh/ NDR 97, Kamesh/ Shusk Samrat, Virendra/ Narendra-80, Narendra-80/ NDR 97 and NDR 97/Shusk samrat have shown significant favourable sca effect for yield and different yield components
