The breeding value is an important genetic parameter determines utility of lines/genotypes to be used as parent
in breeding program. This study was aimed at dissecting the breeding values (combining abilities) in 8 short
duration rice lines for yield and 15 attributing traits. Altogether, 28 F1
s developed under half-diallel fashion
along with eight parents were evaluated. The study revealed importance of both additive and non-additive gene
effects in governing yield and yield components with preponderance of non-additive gene action for most of the
yield components. Additive gene action was found important for 1000-grain weight. The parental genotype
(NUD3) and (NDR 359) were found to be good general combiners. The hybrids namely NDR359/Sarjoo-52,
NDR359/NUD2, NDR359/NDRK5088, NDR359/NDR1, NDR359/Nagina22, NDR359/NUD3, NDR359/CSR10,
Sarjoo52/NDRK5088, Sarjoo52 X NDR 1, NUD 2/NDR1, NUD 2/NUD3, NDRK5088/Nagina22, NDRK5088/
NUD3, NDRK5088/CSR10, NUD 3/Nagina 22, Nagina 22/NUD3, NUD3/CSR 10 have shown significant
favourable sca effect for yield and different yield components.
