TL;DRAbstract
To study the chromosome elimination of PMC MI in Amphiploid SDAU18 from Ae. ventricosa and Ae. cylindrica. The chromosome configuration of SDAU18 and its parents was observed by improved carbol fuchsin methods. The results indicated that chromosome loss of ranged number in partial PMCs MI in one anther of SDAU18 was observed. The average frequency of chromosome-lost PMC MI was 4.64%, and the mean configuration of chromosome-lost PMCs MI was 2n=12.77I+5.26IIR+1.57IIO+0.02III=26.49. However, PMCs MI with abnormal number in its parents weren't found, each cell had 14 bivalents. The chromosome elimination of SDAU18 PMCs MI was rare.
