Comparative mapping of QTLs determining glume, pistil and stamen sizes in cultivated rice (Oryza sativa L.)
With 2 figures and 2 tables To clarify the genetic factors generating intraspecific variations of floral traits in cultivated rice, QTL analyses were performed using five mapping populations: Milyang23/Akihikari recombinant inbred lines (RILs); Asominori/IR24 RILs; Nipponbare/Kasalath backcross inbr...

| description | With 2 figures and 2 tables To clarify the genetic factors generating intraspecific variations of floral traits in cultivated rice, QTL analyses were performed using five mapping populations: Milyang23/Akihikari recombinant inbred lines (RILs); Asominori/IR24 RILs; Nipponbare/Kasalath backcross inbred lines; IR64/Azucena doubled haploid lines; and IR64/Kinandang Patong F2 lines. Totally 160 QTLs for 10 floral traits were detected in these populations. Comparison of all QTL locations in each trait revealed that totally 99 for glume, 43 for pistil and 18 QTLs for stamen traits detected were widely distributed in 80, 36 and 14 chromosome regions, respectively. This indicates that many regions were associated with variations of floral traits in cultivar. Most of the QTLs for pistil and stamen traits showed small phenotypic effects in the five populations. Although many QTLs for the glume traits also had small effects, some QTLs for glume length and width showed large effects. These suggest that few QTLs with large effects may play a key role in variation of glume size while many QTLs with small effects may control variations of pistil and stamen sizes. |
