By using the Neighbor-joining method, a dendrogram was obtained based on genetic distances. The bootstrap values were evaluated for each crunode of the dendrogram by means of bootstrap test. The results showed that the mean heterozygosity of the whole native egg-typing duck breeds population was lower than those of native chicken breeds and goose breeds, suggesting that the genetic diversity in those duck breeds population is relativly rare and should be strengthened. The rank of the heterozygosity was consistent with that of the polymorphism information content. The results of the genetic distances between them indicated that the differentiation occurred long time ago. In the dendrogram, Weishan pocked, Youxian pocked, Huainan pocked, Guangxi pocked and Jingjiang pocked were classified into one goup, Chaohuand Enshi pocked were the second group, Liancheng white, Putian black, Jinding, Shanma, Sansui and Shaoxing were the flnra grong.

结果表明：我国所有蛋鸭品种全部群体的平均杂合度较低，其遗传多样性相对贫乏，各保种场要加强多样性的保护；各品种的平均多态信息含量的高低与群体平均杂合度的顺序完全一致；遗传距离的计算说明了13个品种的遗传距离较远，分化时间较长；13个地方蛋鸭品种被聚类为3个类，微山麻鸭、攸县麻鸭、淮南麻鸭、广西小麻鸭、荆江麻鸭聚为一类；巢湖鸭和恩施麻鸭聚为一类；福建省的鸭种连城白鸭、莆田黑鸭、金定鸭、山麻鸭与三穗鸭、绍兴鸭聚为一类。

Grass of willow leaf horsewhip because plant is lofty, plant the question on potted management is very much, lofty cauline wind is blown or collide to fold caustic easily artificially for example, after blossomming, carry wait not easily, before not quite the farmer is willing to be planted commodity is trafficced, in recent years the farm be current because of sightseeing condition, this kind grows the grass of willow leaf horsewhip that exuberant amount jumps over the United States more more just is able to come forward, additional also outside constant somebody thinks grass of Liu Xie horsewhip by accident is edible flavor plant, that is the concern that because of grass of as citric as flavor plant horsewhip the name approachs very much, should reminding Liu Xie horsewhip is careless here is not flavor plant without edible value, be to view and admire crop purely!

柳叶马鞭草由于植株高大，种成盆栽治理上问题很多，例如高大的茎风吹或人为碰撞易折损。开花后运送不易等，以往不太有农民愿意种成商品贩卖，近年因为观光型态的农场盛行，这种生长旺盛数量越多越美的柳叶马鞭草才得以出头，另也外常有人将柳叶马鞭草误以为是可食用的香料植物，那是因为与香料植物柠檬马鞭草名称很接近的关系，在此要提醒柳叶马鞭草不是香料植物没有食用价值，纯粹是观赏作物喔！

It is also clear that among all genetic ariants eentually found to be associated with asthma, only a few will be replicated, and in the same direction, in the majority of well-performed studies.

To study the genetic diversity and evolution of four breeds of Fujian domestic ducks, the 667 bp control region of mitochondrial DNA from 32 individual domestic ducks and eight spot-billed ducks were sequenced. The results showed that in the D-loop region of four domestic duck breeds, the content of A, G, C and T nucleotides was 25.5%, 15.2%, 33.5% and 25.8%, respectively.

为了探讨福建省家鸭的遗传多样性和品种进化，本研究测定了福建省4个地方家鸭品种的32个个体和野生斑嘴鸭8个个体的线粒体DNA D-loop区667bp序列，分析了这4个家鸭品种的遗传多态性及品种进化。

The invention relates to a method for analyzing microbial community structure and composition using single-strand conformation polymorphism technology, which solves the problem that the existing biological assay and analysis methods are difficult to analyze the composition and structure of microbial community.

一种采用单链构象多态性技术分析微生物群落结构组成的方法，它涉及一种分析微生物群落结构组成的方法。它解决了目前现有的生物检测和分析方法难以分析微生物群落的生物组成结构的问题。

The experimented primers could provided higher PIC in Yellow peach,Red-leaf peach,Flat peach,Juicy peach among groups.9 primers were considerable for providing higher PIC for accessions among different groups in Prunus persica.Primers that could provide higher PIC in single group changed from 1 for Juicy peach to 18 for Yellow peach.

在桃种内的各类群中，供试引物在黄肉桃、红叶桃、蟠桃、蜜桃类群中的信息量较大，有9个引物较适宜于对桃种内的各类群多态信息量分析；对于单个类群提供最大信息量的引物，从水蜜桃只有1个引物到黄肉桃有18个。

YAO Jun-Feng, ZHANG Ying, WU Gui-Qin, ZHENG Jiang-Xia, DENG Xue-Mei, YANG NingCollege of Animal Science and Technology, China Agricultural University, Beijing 100094, ChinaSeven single nucleotide polymorphisms were identified by PCR-SSCP and sequencing in the chicken apoA5 gene in F2 chickens from an experimental cross of White Plymouth Rock × Silkies.
