- 摘 要：以二倍体小果型西瓜及其同源四倍体为试材，采用根尖染色体制片及染色体分析技术，对二倍体及同源四倍体西瓜进行了核型分析。结果表明：二倍体小果型西瓜核型公式为2n=2x=22=22m，11对染色体均为中部着丝粒染色体，核不对称系数为58.90%，核型类型属于1A型，为基本对称型；四倍体小果型西瓜核型公式为2n=4x=44=44m，核不对称系数为56.45%，核型特征与二倍体基本一致。表明四倍体小果型西瓜是由其二倍体加倍得到的，为同源四倍体。
- Abstract:
- Taking the diploid and autotetraploid mini-watermelon as meterial,the diploid and autotetraploid mini-watermelons’ karyotype were analyzed using traditional tabletting method.The results showed that the diploid mini-watermelon karyotype formula was 2n=2x=22=22m with the index of the As.k (karyotypic asymmetry) of 58.90%，with 11 pairs metacentric chromosomes.The karyotype belonged to 1A，with ultimately symmetry karyotype.In addition，the tetraploid mini-watermelon karyotype formula was 2n=4x=44=44m，As.k was 56.45%，same as diploid.The results proved that tetraploid mini-watermelon resulted in the chromosome doubling of diploid.
