| Abstract: | A statistical method for mapping quantitative trait loci(QTLs) underlying endosperm traits is proposed.The method is based on a genetic model containing both the direct effects and maternal effects of an endosperm QTL and on an experimental design,in which trait information is from BC_1F_(1:2) endosperms and molecular marker information is from BC_1F_1 plants. Results of computer simulations indicate that the method can efficiently map endosperm QTLs and precisely estimate both the direct and maternal effec... |
