The research has been made on several agronomy characters of sister lines and sister crosses S 1 produced by self-breeding from a single plant of each of four materials as well as the characters of single crosses and modified single crosses composed of crossing sister lines and sister crosses with male parents.
对４个不同材料各一个基本株自交产生的姊妹系及其姊妹种、以及由此配成的普通单交种和改良单交种的若干农艺性状进行分析的结果表明：１）利用早代姊妹种（Ｓ２或Ｓ３）进行制种，可以提高制种产量６０％以上，有的材料Ｓ２代姊妹种的制种产量甚至成倍增加。
3) sister hapolid nuclei
姊妹单倍核
4) sister chromosome
姊妹染色体
5) Sisters

6) sister chromatid exchange
姊妹染色体交换

Objective To study the mutagenic action of antiepileptic drugs(AEDs), and find an effective way to prevent the mutagenesis induced by AEDs,by observing the effects of AEDs on serum folic acid(FA) level and sister chromatid exchange (SCE) frequency in epileptic children.
目的 通过检测外周血淋巴细胞姊妹染色体交换 (SCE)频率及血清叶酸 (FA)水平 ,研究抗癫药物 (AEDs)对机体的诱变作用及其对FA代谢的影响 ,寻求抗诱变作用的途径。

Objective: By observing the effects of antiepileptic drugs (AEDs) on serum folic acid (FA) level and sister chromatid exchange (SCE) frequency in epileptic children, we study the mutagenesis effect of AEDs, and lood for effective way to prevent chromosome damage or mutagenesis induced by carbamazepine (CBZ) and valproic acid (VPA).
目的：通过检测外周血淋巴细胞姊妹染色体交换（sister chromatid exchange， SCE）频率及血清叶酸（folic acid， FA）水平，来研究抗癫痫药物（antiepileptic drugs， AEDs）对机体的诱变作用及其对FA代谢的影响，并寻求抗诱变作用的途径。
补充资料：二倍体
二倍体
diploid
细胞含有两组染色体的个体。几乎全部高等动物和一半以上的高等植物都是二倍体。人类正常体细胞的染色体有46条，其中一组(23条）来自精子，另一组(23条）来自卵子，形成的合子含23对染色体(即n=23、2n=46）。
