After analyzing glutinous rice waxy gene sequence reported by previous studies, two pairs of dominant and codominant STS molecular markers based PCR were designed for distinguishing glutinous rice, according to the distinctions between glutinous rice wx gene and nonglutinous rice Wx gene. Moreover, the whole sequences of the two Wx genes of nonglutinous rice reported by others were also aligned, and another two pairs of dominant STS molecular markers were designed to discriminate Wxa from Wxb based on the special site between the two genotypes. Then, corresponding rice genotypes were identified by the established new markers.

通过对前人公布的糯性水稻蜡质基因全序列测定结果的分析，根据糯性水稻与非糯性水稻蜡质基因序列位点的差异，设计了两个基于PCR扩增反应的可特异识别糯性水稻的显性和共显性STS分子标记；同时在前人公布的非糯性水稻蜡质基因的不同类型的全序列比对分析的基础上，选取了两种基因型特定的差异位点，设计了两个基于PCR扩增反应用于特异识别这两种Wx基因的显性STS分子标记，并用新建立的标记对相应的水稻基因型进行了检测。

The data show that:(1) The chromosome number of Andrias davidianus is 2n=60.(2) The karyotype consists of macrochromosomes and microchromosomes.(3) In macrochromosomes, eight pairs are metacentric and two pairs are submetacentric.(4) Andrias davidianus has 20 pairs of microchromosomes, among which are four pairs of bi-armed chromosomes. They are No.11, No.25, No.23 and No.24. Other microchromosomes are telecentric.

结果表明：(1)中国大鲵染色体数目为2n=60；(2)染色体由大染色体和微小染色体组成，属于两型性染色体；(3)大染色体中有8对中部着丝粒染色体和2对亚中部着丝粒染色体；(4)微小染色体有20对，大多是端部着丝粒染色体，在雌性中发现了4对双臂染色体，第11、25号是亚中部着丝粒染色体，第23、24号是中部着丝粒染色体。

Five pairs of 45S rDNA loci and two pairs of 5S rDNA signals were detected on chromosomes of Cucurbita moschata Duch. Luffa cylindrical Roem. contained five pairs of 45S rDNA loci and one pair of 5S rDNA loci. In Benincasa hispida Cogn., two pairs of 45S rDNA sites and one pair of 5S rDNA site were detected. In this species, 5S rDNA and one pair of the 45S loci were collocated closely in chromosome 7S. 45S rDNA chromosomal distribution patterns were highly conserved among the three species, althoufh their number varied markedly. The 5S rDNA sites on chromosomes among the three species were highly polymorphic.

南瓜有5对45S rDNA位点， 2对5S rDNA位点；丝瓜具有5对45S rDNA位点， 1对5S rDNA位点；冬瓜具有2对45S rDNA位点， 1对5S rDNA位点， 5S rDNA位点与其中一对45S rDNA位点都位于7号染色体短臂上，并在物理位置上紧密相邻。45S rDNA在这3种作物染色体上数目变化较大，但在染色体上都倾向分布在短臂末端，其分布模式较为一致。5S rDNA在这3种作物染色体上数目相对保守，但在染色体上分布的位置变化较大。
