Research Abstract

To reveal the genetic architecture of inbreeding depression, the QTL analysis of inbreeding depression was conducted in a threatened plant, Primula sieboldii. The progeny which have the allele derived from a common ancestry around the locus ga0343, showed high probability of being albino, small leaf, late budding and small number of flowers. This result suggested that there is a deleterious recessive allele around the locus ga0343
