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.
Key Words: endosperm trait maximum likelihood estimation North Carolina Design III QTL mapping triple test cross
