In this study, the male sterile female fertile mutants-S903Bwas the new one in spring soybean with relatively short growth period. It canbe used in soybean recurrent selection program and has its potential in soybeanbreeding. Anyhow, it is essential to take allelism tests if S903B mutant wasallelism with 〓 to 〓.

本研究所发现和研究的S903B雄性不育系，为我国南方春大豆中第一个较早熟的隐性核不育大豆基因型，表现为雄性不育、雌性可育，在大豆的轮回选择育种中应有巨大的利用潜力。S903B突变体是否与〓-〓等位，还需进行等位性测验。

Mapping of microsatellite markers in two wheat crosses segregating for Pm23 and Pm4b, respectively, in combination with the reported mapping of Pm4a, indicated that the three genes were all linked to the marker Xgwm356 with a distance of 3-5 cM. Allelism between Pm4b and Pm23 was then confirmed, when the progenies of a cross between VPM1 (Pm4b) and Line 81-7241, were shown to be all resistant to a B.

利用获得的8个标记对Pm4b进行遗传作图，结果表明，4个标记与Pm4b连锁(Xgwm356、Xgdm93、Xbar76和Xbarc122)。3个抗白粉病基因(Pm4a、Pm4b和Pm23)均与标记Xgwm356连锁，遗传距离为3-5cM，等位性测验证明Pm23与Pm4b为等位基因。

While doing the RFLP tagging of giant embryogene,the genome changebetween mutants and its original parent,the relationship between RFLP andheteroses in indica,japonica and intermediate rice,the performance of multipleand null allelism in rice varieties,the utilization of null allelic RFLP probes inidentifying indica and japonica rice specifically,the distribution of the nullallelic RFLP probe RG684 in rice cultivars,and the segregations of RFLPmakers in indica/japonica F2 population were also studied.

本实验从经典遗传、分子遗传、育种潜力评估、育种新品系选育等领域，对巨大胚、甜胚乳、暗胚乳三种新型突变体进行了全面系统研究。在对巨大胚进行分子定位过程中，对涉及到的突变体与原始亲本基因组变化，籼、粳、中间型材料的RFLP多态性与杂种优势之间关系，水稻品种的复等位、零等位表现，鉴定籼、粳特异性的零等位RFLP标记，零等位标记RG684在稻种中分布，RFLP标记在籼粳交F2群体中分离等遗传现象也一并进行了分析。

The interactions between the alleles controlling the crossability of wheat with rye may exist.

小麦可杂交性基因间存在互作，表现为纯合隐性等位基因对其它显性等位基因的抑制作用，而纯合隐性等位基因间的效应具有可加性。

Isogenic research on aroma gene showed that aroma gene between Luxianghui 2 and 6 aromatic CMS lines was isogenic genes.

香味基因的等位性研究结果，泸香恢2号与6个香型不育系的香味基因是等位的。

The result indicates that there are one dominant and one recessive complementary gene that are effective against the Indian race 2E16. However, the monosomic analysis results indicated there was one resistant gene to the Indian race 2E16 and the gene was located on chromosome 3B. The current study shows that it is different from the known genes.

采用常规杂交分析方法，对铭贤169与阿夫杂交的F_1、F_2、BC_1代及其亲本进行抗性鉴定和统计分析，结果表明，阿夫对2E16菌系的抗性至少由1对显性抗条锈基因控制；通过单体分析将阿夫抗2E16菌系的1对显性基因定位在3B染色体上，等位性分析表明该基因不同于目前的已知基因。

The experiment obtains clone pig HUMMLC2B gene (GenBank logs onto date: DQ533994), use PCR-RFLP technology, analysed HUMMLC2B gene the 1st embedded child medium Msp Ⅰ is enzymatic cut much condition (T613C) is in distributinging; analysed the much condition sex in 7 breed pig 5 many condition sex and 36 long white pigs, groups 104 pigs and grow to be mixed in vain 5, the result makes clear, the scale that waits for a gene and B to wait for a gene frequency except the A in long white pig in detected swinery is 1 ∶ 2 outside, of the others all take absolutely advantage for a gene such as B, and a gene such as A is pure close individual detect in long white pig only.

实验获得克隆猪HUMMLC2B基因(GenBank登录号：DQ533994)，并采用PCR-RFLP技术，分析了HUMMLC2B基因第1内含子中的MspⅠ酶切多态(T613C)在7个品种猪中的多态性分布；分析了多态性和36头长白猪、5个群体104头猪以及长白和5个群体之和的140头猪胴体性状和肉质性状间的相关，结果表明，在检测的猪群中除长白猪中A等位基因和B等位基因频率的比例为1∶2外，其余的均为B等位基因占绝对优势，且A等位基因纯合个体只在长白猪中检测到。

There may be synergistic action between D and T alleles in pedigreed primary hypertension.

结论家族性原发性高血压与ACE基因I/D多态性及CYP11B2基因T（-344）C多态性之间具有相关性。D及T等位基因频率增高是原发性高血压患者家族中ACE基因I/D多态性及CYP11B2基因T（-344）C多态性的分布特点。D及T等位基因可能在家族性原发性高血压遗传中起协同作用。
