一个水稻突变体呈现叶片无中脉、内稃比外稃长、内外稃不闭合和雌蕊同源异型转化为雄蕊或 雄蕊／雌蕊中间器官等突变表型．用该突变体作父本，０２４２８，Ｎ６２５，中丹２号和ＣＤＲ２２为母本配制杂交 组合进行性状遗传分析，根据Ｆ２代植株的表型Ｘ２测验结果证明突变性状是由单隐性基因控制的．选 用突变体为父本，Ｎ６２５为母本杂交的Ｆ２群体作定位群体，利用ＳＳＬＰ标记和ＲＦＬＰ标记将与突变性状相 关的基因定位在第３染色体短臂上２个相近的分子标记之间，暂称为ｄｌ（ｔ）．
A rice mutant showed no leaf veins, long internal fimbriae than external fimbriae, internal and external fimbriae non-closure, and pistil homeopathic transformed into mutant phenotypes such as stamens or stamens / pistil middle organs. According to the phenotypic X2 test of F2 generation, the mutant trait was controlled by a single recessive gene, using the mutant as a male parent, 02428, N625, Zhongdan 2 and CDR22 as the female parent for genetic analysis. . The mutant was used as the male parent and the F2 population of N625 as female parent was used as the locus group. The genes related to the mutant trait were located between two similar molecular markers on the short arm of chromosome 3 using SSLP and RFLP markers Called dl (t).
