The data byχ~2 were consistent with the separation ratio as 1: 2: 1 χ~2=4.028＜χ_(0.05,2~2=5.99, which further conformed that glandless character was controlled by a incomplete dominance gene, Gl_2~e. 2. SSR markers every about 5cM were selected in the chromosome 12 of our lab genetic linkage map to screen the parent plants. The markers with the polymorphism were used to amplify the DNA of 210 F_2 segregating plants selected randomly and recorded the marker genotypes. After eliminating the segregation distortion markers byχ~2 test, other SSR markers were detected by linkage analysis.

二、参照本实验室海陆种间遗传连锁图谱第12染色体上的SSR标记，平均每5cM左右选择一个标记进行亲本多态性的筛选，筛选出具有多态性的标记位点进一步扩增随机抽取的210个F_2群体单株的DNA，鉴定每个个体的标记基因型。X~2检测剔除偏分离标记后进行连锁分析，发现Gl_2~e基因位于CIR362与NAU5079之间，进一步参考图谱上位于CIR362与NAU5079之间的标记加密图谱，最终将其定位在CIR362和NAU2251b、NAU3860b、STV033之间。

Second Municipal People's Hospital of Guangzhou, Guangzhou 510150 Objective To study the technique and diagnostic value of fluorescence insitu hybridization in chromosome abnormality for prenatal diagnosis. Methods Amniocenteses were performed in 34 pregnant women of 16～23 gestational weeks with indications for prenatal diagnosis. The amniotic fluid samples were cultured in Chang's medium.
