The variation rates of four wheat lines were 2%~3%. The characters of SP1 variation plants at maturity stage also appeared big changes. SP1 variation plants had short growing period, high seed setting rate, loose plant-type and clavated spike-type. There were not consistent change in plant height, the number of spike grain and the weight of 1000 kernel among four lines.

四个小麦品种SP1代变异株率为2％～3％；成熟期SP1代变异株性状也有较大变化，表现为生育期显著缩短，结实率有所提高，株型向松散趋势发展，穗型则均表现为棍棒形，株高、穗粒数和千粒重的变化品种间表现不一致。

The results of in-door antagonism experiment of PSB3 to 12 strains of Fusarium and Colletotrichum showed that PSB3 had antagonism reaction against 6 of the 12 pathogens.

A mixed linear model approach and its software were used to detect QTLs with main effect, QTLs involved in digenic interactions and Q×E interactions.

采用基于混合线性模型的复合区间作图法和相应的作图软件QTLmapper/V2.0，分别定位了7个株高和6个穗位高QTL；检测到18对控制株高和13对控制穗位高的上位性效应位点；同时发现了与环境存在显著互作的6个株高和8个穗位高单位点标记区域以及4对株高和4对穗位高上位性效应区域。

The research displayed that yeasts Genus level can be discerned by agarose gel electrophoresis and polyacarylamide gel electrophoresis, but the latter is more advanced. The Saccharomyces cerevisiae strains ITS-1 sequences are most disalike, few of them are equal completely. The bigger differences are part of base pairs about Poly-T, others are exchanged by single base pair.

研究表明，以酵母菌株的rDNA ITS-1序列进行琼脂糖凝胶电泳，能把菌株分类鉴定到属的水平；采用非变性聚丙烯酰胺凝胶电泳能把部分酿酒酵母菌株分类鉴定到种的水平，区别效果较琼脂糖凝胶电泳有所提高；对rDNA ITS-1序列进行克隆、测序，经序列比对后发现，酿酒酵母属中酿酒酵母菌株的ITS-1序列大多数有差异，差异主要表现在ITS-1序列上游的一段Poly-T碱基上，其它处的差异仅是个别碱基的转换或颠换，ITS-1序列长度分布在360-370bp之间，G+C%含量均在35.3%左右。

Results 10 strains of salmonella enteritidis appear multi-antibiotics resistance. These strains were subtyped into 3 groups A, B, C according to the electrophoresis profiles sinilarity 85% standard or above, including 2 strains, 6strains and 2 strains respectively.

结果 药敏呈现出多重耐药；基因谱系与聚类分析可将菌株分为3大类，扩增片段长度为250bp~2000bp，在85%的同源度上可分为A、B、C等3个型，其中A型2株，B型6株，C型2株。

Enteritidis strains of patient and food of Global Salm-Surv from 2006 to 2007 were tested;including phenotype confirmation,antibiotic resistance and pulsed-field gel electrophoresis analysis.［Results］S. Enteritidis was the topmost strains in diarrhea patients caused by non-typhi Salmonella in 2006 to 2007,in Shanghai. 80% strains of food-borne S.
