摘要：

A cold-germinable (CG) fine of muskmelon (Cacumis melo L.) derived from PI 126156 was crossed to a noncold-germinable (NCG) line derived from 'Delicious 51'. Seed of parents and reciprocal F1, F2, and BC families were incubated for 14 days on absorbent wadding in petri dishes at 15C. Days elapsed to radicle emergence among progeny from reciprocal crosses and segregating populations indicated the existence in the CG line of a cytoplasmic factor and recessive nuclear genes for cold germinability. Based on F2 and BC segregation, it appears that at least three or four recessive genes confer cold germinability. High levels of cold germinability in a seed population required the presence of both the cytoplasmic factor and nuclear genes for cold germinability.
