Abstract
Five tertiary trisomics, isolated in the progenies of interchange heterozygotes, were morphologically classified into four groups. They might be named as slender, succulent, enlarged internode and small-erect stipule, respectively. At MI, characteristic pentavalent configuration was accounted in 38.4% cells; the modal configuration was 1111+6II (50.0 %). At AI, 7-8 disjunction was about 66.7%. Pollen fertility ranged from 30 4 to 67.0 %, while seed yield was very poor, ranging from 0-4 seeds per plant.
