The process of map-based cloning of qGW4.05. a Location of qGW4.05 on chromosome 4, mapped using the F2 population in 2012. b and c The genotypes and phenotypes of different recombination types selected from the F2 population in 2012 and 2013. These recombinants of the two F2 populations were both classified into seven types. The genetic structure for each type is depicted as black, white, or grey rectangles, representing homozygous Huangzaosi/Huangzaosi, homozygous LV28/LV28, and heterozygous Huangzaosi/LV28, respectively. The tables on the right show the variations in 100-kernel weight, 10-kernel length and 10-kernel width of each recombinant type between different genotypes, and the total number (NO.) of plants refers to all plants of a given recombinant type in the F2 populations. **, significantly different at P < 0.01; NS no significant difference at the P < 0.01 level. These findings suggested that the qGW4.05 allele from Huangzaosi can increase the 100-kernel weight, 10-kernel length and 10-kernel width. The interval of qGW4.05 could be narrowed down from an ~1.08-Mb to an ~279.60-Kb region that was flanked by the markers NO4 and ND4M26
