From: Updating the elite rice variety Kongyu 131 by improving the Gn1a locus
Marker-trait analysis of the random subpopulation BC3F2-LQ96 derived from BC3F1-22F01 using Kongyu 131 as the recurrent parent and GKBR as the donor parent. a-d LOD score of 4 yield-related traits; the horizontal axis represents the 160 SNP markers on 12 chromosomes. e-h Comparison of 4 yield-related traits of Kongyu 131 and three genotypic classes of the Gn1a locus. −/− represents homozygote for Kongyu 131, +/− represents heterozygote, and +/+ represents homozygote for GKBR. a and e Number of primary branches per panicle (NPB). b and f Density of primary branches (DPB, /cm). c and g Grain number per panicle (GNP). d and h Grain density per panicle (GDP, /cm). e-h A, B, C ranked by Student’s t-tests at P ≤ 0.01; a, b, c, ranked by Student’s t-tests at P ≤ 0.05
