In the genetic background tested by whole-genome resequencing and marker analysis, this population was segregated at Hd16 but homozygous at all the remaining 11 cloned quantitative trait loci (QTL) for HD, including OsMADS51, DTH2, OsMADS50/DTH3, Hd6, Hd17, RFT1, Hd3a, OsPRR37/Ghd7.1/DTH7/Hd2, Hd18, DTH8/Ghd8 and Ehd1. The effects of Hd1 and Ghd7 on HD were tested under NSD conditions in Lingshui from Dec. This evidence concerns the gene EHD1 and Huntington disease.
