摘要: 采用压片法对亚麻C-H-89品种进行染色体核型分析研究。结果表明,亚麻C-H-89品种为二倍体,染色体数目为15对,其核型公式为2n=2x=30=26m+4sm,核型类型为"2B",染色体长度比2.23,染色体臂指数NF值=60,核型不对称系数As.k.%=56.66%。

Abstract: Chromosome karyotype analysis of flax varieties C-H-89 was made by the method of tablet. Results showed that C- H-89 varieties was diploid, and contained 15 pairs of chromosomes. Its karyotype formula was n=2x2=30m+4=26 sm. Karyotype classification was the type of "2 B".The length ratio of the chromosome was 2.23, Chromosome arm index values was NF=60, Karyotype asymmetry coefficient was 56.66%.
