Abstract: Three Cytoplasmic male sterile lines and 10 restorers and their 30 indica hybrids were used to investigate the heterosis of 9 paddy grain quality characters, i.e., brown rice percentage (BP), head rice percentage (HP), grain length (GL), grain width (GW), weight of grains(WG), chalkiness score(CS),

Key words: Indica rice hybrids, Paddy grain, quality, Heterosis from mid-parent value, Heterosis over parents
