It was found that the chromosomes involved in translocation were chromosome 10 and 11 in stead of chromosome 9 and 12 as being compared with the karyotype of Nipponbare.So we consider that the chromosome 9 and 12 in the present rice chromosome numbering system could be chromosome 10 and 11 according to their length,arm ratio and the relationship with nucleolus.

结果表明，该易位系的易位染色体并非第9和第12染色体，而是第10和第11染色体，从而认为目前国际上统一编号的第9、12染色体，根据染色体的实际长度可能分别为第10、11染色体。

With the seeds of artificially cultivated 2-year-old A. heterophyllum as tested materials, the cells in metaphase in the seeds were made for observation, statistic and karyotype analysis, and based on the 2 main features of length ratio and arm ratio of chromosome, the karyotypes were classified according to the criteria of Stebbins.

方法］以人工栽培的2年生异叶天南星种子为试材，观察种子中的中期分裂相细胞并对其进行统计和核型分析，其核型分类根据核型中染色体的长度比和臂比2项主要特征，按Stebbins的标准进行划分。

The formula of chromosome karyotype of A. heterophyllum was 2n=28=18m+10sm, its chromosome relative length was in the range of 24.464%-63.245%, the ratio of the longest chromosome to the shortest chromosome was 2.58 and the chromosomes with arm ratio above 2:1 accounted for 14.3% in total chromosomes.
