Abstract
Photomicrographs of chromosomal configurations in nuclei of squashed whole mounts of mature oospores (cultures 32 days old) of Phytophthora capsici stained with iron hematoxylin were interpreted to indicate that meiosis occurred in the oospore. Chromosomes in dividing oospore nuclei were observed in synapsis, diakinesis, metaphase I, and metaphase II. Comparison of polar metaphase I and metaphase II plates revealed a reduction in chromosome size and number and nuclear size. The haploid number of chromosomes was interpreted to be 6.Keywords
