From: Identification of Heterotic Loci with Desirable Allelic Interaction to Increase Yield in Rice
Yield mid-parent heterosis (MPH) of 10 allelic combinations at Ghd8 in heterozygotes within the background of ZS97. a Schematic gene mode showing nucleotide variations in the coding region of Ghd8 among five parents (NIP, ZS97, 9311, ACC10 and MH63). NIP (Nipponbare) is used as a reference. Polymorphic nucleotides are indicated by different color lines. “F” and “N” denote functional and non-functional alleles, respectively. b Plant image of five NILs (NIL-Ghd8ZS97, NIL-Ghd8NIP, NIL-Ghd89311, NIL-Ghd8ACC10, and NIL-Ghd8MH63). The images were taken at the maturity of NIL-Ghd8ZS97; scale bar, 10 cm. c, d MPH of Ghd8 for spikelet number (SN) and yield per plant (YD) in ten hybrids with different allelic combinations. The error bar represents the mean ± SE (n = 3). NIL-Ghd8NIP, NIL-Ghd89311, NIL-Ghd8ACC10, and NIL-Ghd8MH63 represent those NILs carrying corresponding Ghd8 alleles from different donors within the same ZS97 background, respectively. The different letters denote significant differences by LSD test at P < 0.05. The error bar represents the mean ± SE (n = 3)
