遗传性状

The content of mineral elements in ripe fruits of M.sieversii from 78 seedings at Mohe Town,Gongliu Country were analyzed using Atomic Absorption Spectrophotometer.The results indicated that M.sieversii seedings presented considerable genetic variations in content of mineral elements with the range of variation coefficients from 24.2% to 54.0%.So it has large potential for further selection.Four elite seedlings were selected,namely large fruit type,high Ca content type,high Zn content type and high damascenone content.As the predominant component of Ily wild fruit tree forest,Malus sieversii had occupied an area of 9300ha.But the inherent reproduction system of M.sieversii and genetic diversity of the species were destructed in different degrees,as a result of farming assart,over grazing and damage by Agrilus mali.

上述结果支持"新疆野苹果可能是栽培苹果祖先种"的结论；②对巩留县莫舍乡的新疆野苹果78个实生株系果肉组织Ca、Mg、Fe、Zn、Cu、Mn6种矿质营养元素进行测定的结果表明，每种矿质元素含量单株间差异显著，变异系数在24.2％～54.0％，遗传多样性丰富，进一步选择的潜力很大；③根据新疆野苹果果实形态、香味物质和矿质元素含量等的测定结果，初步筛选出了大果型、高钙型、高锌型和大马酮型等4个特异性状单株；④调查发现，由于农田开垦、过度放牧以及苹果小吉丁虫的蔓延危害，目前伊犁野果林面积逐年减少，野苹果固有的繁育体系和遗传多样性受到不同程度的破坏。

These results indicated some differences from other investigated autopolyploid plants in autopolyploid watermelon. Autotriploid watermelon, in particular, showed unusual characters of genome structure and DNA methylation status, which may be closely associated with the oddploidy effect and the excellent traits present in triploid plants.

综上结果证明，西瓜同源多倍化过程中发生的遗传和表观遗传改变与已报导的一些植物的同源多倍化有所不同，特别是三倍体西瓜，其表现出独特的基因组结构及DNA甲基化状态变化特徵，而这可能与植物的奇倍性效应及三倍体西瓜优良性状的形成密切相关。

The results showed that the hereditary mode of handedness or preferential foot or hand-clasping is the dominant heredity of single gene of autosome,and the right type of all of them is the dominant character.

Studies on the genetic diversity of Bombyx mandarina M. play an important role in the facets of silkworms breeding, protection of wild resources, and construction of special properties genetic bases and so on.

研究野桑蚕的遗传多样性在遗传育种、野生资源的保护、特殊性状基因库的建立等诸多方面具有非常重要的意义。

The contraction of genetic map using marker information and mapping QTL are the core of Statistical Genomics.

利用群体的遗传标记信息构建动植物的遗传图谱和定位分析影响数量性状的基因位点是统计基因组学的核心内容。

There were two genotypesin China Merino fecundity sheep,the BB and B+ mutation genotype was superior in Chinese merino fecundity sheep,the ewes with genotype BB and B+had 4.0 and 3.5 ovulations,genotype ++ had 1.56 ovulations averagely,The BB and B+ mutation genotypes were 2.44(P.01)and 1.94(P.01)ovulations more than with genotype ++ in the Chinese merino sheep.

绵羊的多胎是绵羊业多产、高产的基础。一般来说，家畜的繁殖性状是受多基因控制的数量性状，传统的选择方法对其遗传进展的改良是很慢的，世代间隔长。分子标记辅助选择为解决这一问题提供了新的方向和契机。

Analysis of genetic path were carried out based on nine basic characters, cocoon shell weight, pupa weight, whloe cocooa weight, cocoon shell percentage, cocoon production per ten thousand larvae, number of mature eggs in oviducts, number of eggs laid by per mother moth and egg-laying efficiency.

对茧层重、蛹体重、全茧重、茧层率、万蚕收茧量、万蚕茧层量、造卵数、产卵数和产卵效率等9项性状作了遗传通径分析，并根据性状间的相互关系，将各别的通径图有序地连接起来，形成通径网络。

The variation made up in all of the traits was mostly inherited,and the additive genetic correlations between each pair of the majority of traits studied were apparent.

大多数性状间的加性遗传相关明显。因此，杂交早代对这些性状的直接和间接选择都是有效的。
