Abstract

A mapping population can be used to map genetic markers through linkage. Thus, the population can be constructed by hybridizing two dissimilar genotypes. It identifies the distance between the two linked genes, which in turn is used to construct a genetic map. Primary mapping populations are constructed by hybridizing two homozygous lines with distinct characters, while the secondary mapping population consists of hybridizing the individuals from a developed mapping population.
