Abstract

In the study, floral buds of two varieties of chinese cherry "Bijie 7", "Zunyi 3" were used for chromosome staining as well as karyotype analysis. As the result shows, the chromosome number of cultivated species "Bijie 7" is 32. The karyotype formula is 2n=4x=32=32m, the ratio of chromosome length (L/S) is 1.75, and the constitution of the relative length is 4L+8M2+20M1. The relative lengths range from 10.17%-17.76%, the centromeric index range from 39.58%-47.32%, and arm ratio rank from 1.11 to 1.53. Karyotype characteristics fall into type 1A according to Stebbins classification criteria. Cultivated species "Zunyi 3"possesses the same chromosome number and karyotype formula as "Bijie 7", while the ratio of chromosome length (L/S) is 1.69, the constitution of the relative length is 4L+8M2+20M1. The relative lengths range from 9.66%-16.33%, the centromeric index range from 37.22%-43.78%, and arm ratio rankd from 1.28 to 1.69. Karyotype characteristics fall into type 1A.
