Abstract

Abstract: Chromosomes behaviors of pollen mother cells (PMCs) of autotetraploid carrot (2n=4x=36) were observed using enzymes digestion technique. There were more than two nucleoli in about 4.58% PMCs at premeiotic interphase and prophaseⅠ. Besides bivalents, univalents and multivalents were observed at diakinesis and metaphaseⅠ. Some chromosomes (about 1 to 6) were found not to rank on the metaphase plate in about 23.0% PMCs at metaphaseⅠand 32.3% PMCs at metaphaseⅡ, respectively. The average chromosome configuration was 0.86Ⅰ+4.01Ⅱ+2.99Ⅲ+1.89Ⅳ+0.81Ⅴ+1.09Ⅵ. Chromosome lagging, chromosome bridge and spindle mis-orientation were also observed. Abnormal chromosome behavior of PMCs was reason for polymorphism of male gametophytes and lower fertility of pollen in autotetraploid carrot.

Key words: carrot, autotetraploid, meiosis
