Gametic selection was assessed with a doubled haploid population including 1 35 lines derived from anther culture of a typical indica and /japonica cross, ZYQ 8/JX 1 7, by investigating the segregation and recombination of morphological characters, isozymes and RFLP markers.

对典型的灿与粳稻杂种，窄叶青8号／京系17F1花药进行培养获得的132个双单倍体的形态特性、同工酶与RFLP标记的分离与重组进行了考察分析，研究是否存在配子选择问题。

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.
