Using the acetocarmine squash technique to examine pollen mother cells, the meiotic chromosome behavior of each of 16 Rhoeo spathacea plants housed in the Ball State University greenhouse was analyzed with respect to the frequencies of several types of atnormalities and documented with suitable photomicrographs. Among the aberrant types of chromosome behavior resulting from multiple translocations among the 12 chromosomes of each plant were the followings ring and chain formation of chromosomes at diakinesis and metaphase I, adjacent versus alternate chromosome alignment patterns at metaphse I and anaphase I, various abnormal anaphase I and telophase I disjunction patterns, and the presence of excluded chromosomes and micronuclei at telophase I. As a further consequence of the multiple translocations and abnormal chromosome disjunction, many of the pollen grains formed by meiosis were found to be defective and non-viable.Ball State UniversityMuncie, IN 47306
