| Abstract: | The chromosome number and karyotype of Henan cucumber No.2 were studied by using the improved wall degradation hypotonic method.The results showed that: its chromosome number was 14;its karyotype formula was 2n=2x=14=14m;its asymmetry index was 54.85;its constitution of relative length was 2n=14=6M2 8M1.Based on the standard of Stebbins's classification,its karyotype was "1A" type. |
