遗传性状

In the study 101 local varieties, 83 modern cultivars, 72 new families of wheat were analysed for the days of callusing at 50%, the number of callusing in 4 weeks in callus induction; and rate of Calli of root formation and the rate of calli of shoot formation in differentiation culture.

为了选育商业应用价值好的新品种，作为受体的植物还需要农艺性状好，育种价值高。一个关键问题是，遗传转化技术是建立在植物的细胞和组织通过组织培养过程再生植株的技术体系上。

At the present time, these multiple variables are often switched into a dichotomized variable according to some classification criteria, and then the dichotomized variable is analyzed.

然而，对于复杂性状，我们往往很难判断这种定性划分的准则同疾病基因的遗传有何关系，所以用多个原始变量的数据来定位易感基因可能更为理想。

Maternal genetic effects, however, were not important for these traits with excepts of drip loss, marbling score and storage loss.

生长和肉用性状的母本遗传效应较小(失水率、大理石纹等级、贮存损失例外)。

The segregating ratio between tall and short plants in 8 recrossing rice combinations F1 is 1:1 Plant height and heading day showed independent inheritance.

8个水稻高矮秆杂种以矮秆品种复交组合F_1高矮秆呈1：1分离。控制株高和抽穗日数两对性状是独立遗传的。

The peak of dry matter production rate of density-tolerant variety LiaoDan 565 appeared at tasseling-milk stage, thin density variety DanYu 39 appeared from Tuba mouth stage to tasseling stages, which earlier than density-tolerant variety.

这一差异导致稀植品种由于前期徒长、经济系数下降而减产；相反密植品种由于干物质的运输与贮藏相对协调而高产。5、在密植育种中，很多性状在高低两种种植密度下的遗传特性存在较大差异。

Positive effects of SCA and dominance for tuber yield were significant with CH72.03×11379-03, and 08675-21×10875-04 showed significant negative effect of dominance for chipping color.

极显著的加性效应和较低的狭义遗传率(42.5％)说明基因累加作用对干物质含量的改良极为重要，该性状受微效多基因控制。

Dendrogram analysis showed genetic relationships among those varieties which have the same genetic resources. Therefore, t...

聚类分析表明，具有相同骨干亲本的育成品种遗传距离较近，这与以往的农艺性状研究及生理生化研究结论相符。

Daughter-dam regression, daughter-dam regression wit hin sire, half-sib correlation and intro-unit half?sib correlation were used in the study to estimate genetic parameters for several traits of Albas type of In ner Mongolia cashmere goats, Traits included in this paper were cashmere yield,cashmere thickness,staple length,body eight,cashmere stretched length and cashmere fineness.

本研究应用女母回归法、公畜内女母回归法、半同胞相关法和单元内半同胞相关法对内蒙古阿尔巴斯白绒山羊的产绒量、绒厚、毛长、体重、绒伸直长度和细度等六个性状的遗传参数进行了估测。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
