Results on breeding and developing hybrid aromatic rice KC06-1

Abstract

The three-line hybrid rice KC06-1 was the cross of MN18A/CT385-31-3-1 by Southern Seed Corporation. Its agronomical features could be characterized as maturity duration of 100-105 days, plant height of 112 cm, good tillering ability, big panicle and 1,000-grain weight of 24.4 g. Multiple trials conducted in Mekong Delta in 2013-2015 revealed that KC06-1 yielded 7-8 tons/ha in the trials, and 9-10 tons/ha in farmer field demonstrations. The hybrid exhibited its yield stability, wide adaptibility in Mekong Delta, with resistance to blast and tolerance to brown planthopper. Its grain shape was long and slender, meeting exportation standard. In addition, the hybrid rice KC06-1 also had aromatic scent, good taste, and amylose content of 17%.
