Abstract
Meiotic behaviour of two partially desynaptic plants of Pennisetum ramosum (Hochst.) Schweinf., a diploid grass with 2n=10 chromosomes, is described. The normally paired chromosomes tended to fall apart at diplotene and post-diplotene stages, so that at metaphase I of several cells (Table 1) the chromosomes looked somewhat disorganized. The disjunctional stages were quite irregular. Different factors-extrinsic as well as intrinsic-which may have led to these meiotic abormalities are discussed.
