Categories of mapping populations and cross combinations used for the detection of representative rice QTLs. a Percentage of total articles using each type of mapping population. RIL recombinant inbred line, DHL doubled haploid line, BIL backcross inbred line, BC 1 F 1 backcross population of F1 × recurrent parent. The F2 population category is further divided according to the number of individuals comprising each population (<1,000 individuals vs ≥1,000 individuals) because these two categories are often used for different objectives. b Cross combinations used in more than 10 articles.
