摘要

The study of meiosis inA. ampeloprasumin Israel showed that in subsp.ampeloprasumthe chiasmata are localised proximally to the centromere, whereas they are terminal or subterminal in subsp.truncatum.It was found that localisation of chiasmata reduces multivalent formation in 4x, 5x and 6x plants of subsp.ampeloprasum.
