Chromosome Configuration Changes with Stages of Anther Development in a Triploid Sorghum Plant1

Abstract

Abstract

The homozygous nature of a triploid sorghum plant derived by selfing a haploid afforded the unique opportunity of studying chromosome behavior without the effect of heterozygosity. Frequency of univalents per cell at metaphase I of meiosis was found to increase while frequency of two trivalent types decreased as stage of anther development progressed. At anaphase I and telophase I, laggards per cell likewise increased at later stages of development of the anthers. These observations may be explained by the tendency of univalents to delay metaphase I so freqency of cells containing univalents would increase at later stages of anther development.
