遗传性状

Congenital element, because be born before, of pregnant woman hidebound, systemic sex disease, certain and familial genetic element (if the tooth is mixed,the character of jaw bone and size often affect a tooth, cause dental amlposition or jackknife to wait); Acquired element, basically be undesirable habit (consistent side sex is masticatory, buccal breath, make force of parity of tongue, lip, buccal share is destroyed, those who cause jaw growth is not not well-balanced, harmonious) with all sorts of tooth disease.

先天因素，由于出生前，孕妇的营养不良，全身性疾病，某些家族的遗传因素（如牙齿和颌骨的性状和大小常常影响牙位，造成牙齿错位或重叠等）；后天因素，主要是不良习惯（如一侧性咀嚼，口呼吸等，使舌、唇、颊部分均势力量受到破坏，导致面颌发育的不匀称、不协调）和各种牙病。

The construction of genetic linkage groups and the mapping of QTL for quality, resistance and agronomic traits are main components of plant genomics research.

遗传连锁图谱构建和重要品质、抗性和农艺性状的QTL定位是植物基因组学研究的重要内容。

Eryou long-pod,which was derived from the unique long-pod mutant discovered in China,was crossed with the commercial broad rapeseed cultivar Zhongyou 821.From the crossing six basic generations were generated for studying the genetical behaviors of pod length and two related characters i.e.1000?

用在中国发现的甘蓝型油菜长角果变异体的优良后代&鄂油长角&及短角果品种&中油821&为亲本，研究了角果长及与角果长密切相关的两个性状――千粒重和每果粒数的遗传。

Species in the genus Thinopyrum are important wild relatives for wheat improvement. They possess many desirable traits such as drought, cold and salt tolerance, long spikes and more florets, high protein concentration. It has also been found that some species are the source of resistance genes for rust and powdery mildew, and especially, the source of resistance to wheat streak mosaic virus and barley yellow dwarf virus .

偃麦草属植物是小麦遗传改良中的重要野生近缘种，蕴含抗寒、抗旱、耐盐碱及长穗多花、籽粒蛋白质含量高等优良性状，同时又是小麦锈病和白粉病的重要抗源，特别是在小麦条纹花叶病和大麦黄矮病等病毒病的抗病育种中发挥了重要作用。

The range of evolutionary theories during "the eclipse of Darwinism" included forms of "saltationism" in which new species were thought to arise through "jumps" rather than gradual adaptation, forms of orthogenesis claiming that species had an inherent tendency to change in a particular direction, and forms of neo-Lamarckism in which inheritance of acquired characteristics led to progress.

在&达尔文主义衰落时期&，进化理论包括各种形式的&骤变说&，认为新种是通过&跳跃&而不是通过逐渐适应产生的；也包括各种形式的直生论，声称物种有着内在的、向某一特定方向变化的趋势；还包括各种形式的新拉马克主义，认为获得性状遗传导致进步。

It is believed that, with the research development and data enrichment in this field, blood biochemical indexes, will become complementarities for general breeding and will brings a great breakthrough for poultry breeding.

为了探讨利用血液蛋白质多态性作为遗传标记进行早期选种的可能性，一些学者研究了血液蛋白质及酶的多态性与经济性状间的关系，业已取得大量的研究数据。

TO map QTLs affecting grain weight and characterize the inheritancemodes of the QTLs and two-locus interactions, 136 recombinant inbred linesderived from "Nanda2419" x "Wangshuibai" and an immortalized F_2 population (IF2)generated by randomly permutated intermating of these RILs were investigated. In addition,the present study was also conducted to characterize the genetic bases of morphologicaltraits including plant height, flag leaf length, flag leaf width, flag leafarea and ratio of flag leaf length to width, and their relationships with grainweight in wheat by analyzing QTLs for these traits using the RIL population.

本研究利用南大2419x望水白的136个株系的重组自交系群体和由其衍生的永久F_2群体对粒重进行了QTL定位并探讨其遗传方式和上位性互作，同时利用该重组自交系群体对株高以及旗叶长、宽、面积、长宽比等叶部形态学性状进行了QTLs定位并探讨它们与粒重的相关性。
