摘要： Oilseed rape (Brassica napus L.) genotypes with reduced petal size are thought to have advantages in photosynthetic capacity and in disease resistance. This study was conducted to analyze the inheritance of a completely apetalous mutant that was induced by mutagenic treatment. The mutant ap-Tengbe was crossed with the German winter rapeseed cultivar Falcon. The F-1, the F-2, and both backcrosses including reciprocal generations were grown in field experiments at Gottingen, Germany, in 1997-1998 and at Hangzhou, China, in 1998-1999. The apetalous character of ap-Tengbe is regulated by an interaction of cytoplasmic genes and two pairs of nuclear genes. Completely apetalous flowers are only expressed in genotypes with the ap cytoplasm and two homozygous recessive genes. In conclusion, the mutant ap-Tengbe is useful to produce completely apetalous genotypes, but cytoplasmic effects have to be considered.
