| Abstract: | Hengda A was a CMS Line rice bred by multiple-crossing the maintainer lines selected betweenLongtepu B and the filial generation F2 of the hybrid of D6 2B and IR5 802 5B with Zhenshan 9 7A through successivebackcrossing for years.It was registered and released for commercial applications in Fuj ian in 20 1 4.Its outstandingcharacteristics included a complete sterility,high outcrossing rate,large panicle with numerous grains,strongtillering ability and desirable combining capacity.The breeding process,botanical characteristics and performance ofthe hybrid rice varieties of Hengda A are presented. |
