Abstract:

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 designsNorth Carolina Design III (NCIII) and triple test cross (TTC)and demonstrate their efficiency in detecting quantitative trait loci underlying endosperm traits.

Keywords: endosperm trait; maximum likelihood estimation; North Carolina Design III; QTL mapping; triple test cross
