title: Desynapsis and spontaneous trisomy in jute (Corchorus olitorius L.).
abstract: Cytological studies in desynaptic plants, isolated at the F6 generation of an intervarietal cross of Corchorus olitorius L., have shown variable numbers of bivalents and univalents in the PMC's at metaphase I, resulting in irregular distribution of chromosomes at anaphase I. The progenies of the desynaptic plants consisted of 9.24 percent of all possible primary trisomies except trisomie 6. The desynaptic condition is controlled by a pair of simple recessive genes.
