Kato, M. Mii] Abstract : Differences in ploidy level were found in inter-specific hybrids obtained by reciprocal crosses between Primula sieboldii and P. kisoana. When P. sieboldii was used as the maternal parent, the inter-specific hybrids were triploids; when P. kisoana was the maternal parent, the inter-specific hybrids were diploids. The possibility of diploid female gamete formation in P. sieboldii is discussed as a causal factor in the production of triploids occasionally found in crosses between diploids of this species.
