摘　　要：以广东省农业科学院水稻研究所选育的优质常规稻绿黄占为材料,通过60Co辐射诱变,以后代单株M3(辐照M3代)为母本,以三明市农业科学院选育的早熟恢复系明恢77为父本进行杂交,后代经多年系谱选育,育成早熟恢复系福恢342;福恢342与广东粤良种业选育的恒丰A杂交,配组育成了杂交稻组合恒丰优342。经多年示范,表现后期转色好、抗病性好、产量高等优点,于2017年通过福建省农作物品种审定。The high-quality varieties Lvhuangzhan was bred by Guangdong Academy of Agricultural Sciences,taking Lvhuangzhan M3(Lvhuangzhan mutagenesis by 60Co radiation)as female and crossed with early maturing restorer line Minghui 77 which was bred by Sanming Academy of Agricultural Sciences,after breeding for many years by pedigree,the early maturing restorer line Fuhui 342 has been bred,then it was crossed with Hengfeng A,which was selected by YueLiang seed industry in Guangdong,and the combination was named Hengfengyou 342.After years of demonstration,it shows that the group was neat,the plant type was moderate,and it has good leaf colour at later stages,good disease-resistant and high yield.The combination has been certified by Fujian crop variety evaluation committees in 2017.
