General and specific combining ability for some quantitative characters of seven aromatic rice varieties
For the demand of high yield, good grain quality and contribute to domestic consuming and export in the Mekong Delta, the breeding new rice varieties with high yield, good grain quality is necessary. Five high yield aromatic rice varieties and 2 imported traditional rice varieties were selected as parents for half-diallel crosses with the aim of combining ability evaluation in F1 generation. Among 7 varieties, OM7347 and VĐ20 were the best general combiners for the plant height, panicle length, panicles/hill, filled grains/panicle and grain yield. The most promising combiner for panicles/hill, filled grains/panicle and grain yield was OM4900/KDM105; for panicles/hill and grain yield was OM3536/Basmati; for filled grains/panicle and grain yield was OM7347/VĐ20.
