摘要:
A castor plant trisomic for chromosome 2 (2n+ 1 =21) was identified by pachytene analysis. Chromosomes 2 and 7 contained nucleolar organizers in or adjacent to the terminal heterochromatic segment of their respective short arms and, in both, this segment was heteromorphic. The trisomic plant was vigorous, had 92% pollen stainability, and was partially female fertile.
