Improved Genetic Mapping of Endosperm Traits Using NCIII and TTC Designs

X Wang, W Song, Z Yang, Y Wang, Z Tang and C. Xu


The endosperm in plants is a major source of human nutrition and industrial raw material. The genetic study of endosperm poses a great challenge due to its complex genetic composition and unique physical and developmental properties. In this note, we shall revisit 2 classic mating designs—North Carolina Design III (NCIII) and triple test cross (TTC)—and demonstrate their efficiency in detecting quantitative trait loci underlying endosperm traits.
