1) Major K-type male sterile gene rfv1
K型主效不育基因rfv_1
2) rfv_1 gene
rfv_1基因
1.
We chose the non-1BL/1RS wheat with rfv_1 gene on 1BS as the donor and the female parents of strong superiority crosses by CHA method as the receptor to transduct rfv_1 gene directionally and to creat a new non-1BL/1RS maintenance line of NINE Type in wheat.
有鉴于此,本研究将CHA途径与粘类小麦雄性不育三系途径相结合,选用1BS上携有不育基因rfv_1的非1BL/1RS小麦为供体,以杀雄剂途径获得的强优势组合的母本为受体,实现rfv_1基因的定向转入,创制粘类非1BL/1RS小麦雄性不育的新保持系,充分发挥两种途径的优点,以建拓出一套杂交小麦杂种优势利用的新途径,为三系杂交小麦能早日进入生产应用提供理论依据和技术支撑。
3) K-type sterile line
K型不育系
1.
Genetic difference comparisons between the NILs and the K-type sterile line and clustering analysis were carried out in this paper.
以17个小麦K型不育系恢复基因的近等基因系(N1～N17)和轮回亲本不育系豫麦3号为材料,通过调查这些材料的株高、成穗数、旗叶长、旗叶宽、倒二叶长、脖长、倒一节长、倒二节长、穗长、小穗数等10个农艺性状,对小麦K型不育系恢复基因近等基因系的农艺性状进行了差异比较和聚类分析。
5) sterility genes
不育基因

布鲁拉美利奴主效基因在绵羊育种中的应用
2.
The subject of the mixed genetic model that is a single identified locus plus polygenes,the breeding objective that includes two correlative traits,some factors such as major gene variance proportion,heritability and genetic correlation which may act on the RSE were synchronously examined to sort out some vital ones which would be controlled to bring into full play in practic.
利用单个已识别主效基因位点加微效多基因的混合遗传模型,在二性状育种目标下探讨基因型选择[Direct Selection of Quantitative Trait Loci(QTL),DSQ]的相对选择效率(Relative Selection Efficiency,RSE),并考察主效基因方差贡献、性状遗传力和遗传相关对RSE的影响,以期找出控制RSE实际应用中的主要影响因素,并最大限度地发挥已识别主效QTL位点在育种中的作用。
3.
