陆地棉 光敏雄性不育 基因控制 隐性性状
2024/4/16
陆地棉光敏雄性不育系中9106是在中040029的后代中发现的突变体，它在长日照（河南安阳）条件下表现为彻底的雄性不育。以陆地棉乐土603、TM-1和海岛棉海7124为父本分别配置F2杂交组合发现中9106的雄性不育性状是受一对核基因控制的隐性性状。利用以全基因组测序为基础的分离群体群分法和以中9106×TM-1的F2群体进行的图位克隆，将中9106的雄性不育基因定位在D12染色体上QZD84和Q...

Inheritance of fertility restoration of the A4 system of cytoplasmic-nuclear male sterility in pearl millet was investigated using six crosses between two diverse male sterile lines (A-lines) and thre...
Sequence analysis of the mtDNA region correlated with Shaan 2A cytoplasmic male sterility in rapeseed (Brassica napus L.)
cytoplasmic male sterility (CMS) marker-assisted selection (MAS) orf224-1 rapeseed (Brassica napus L.) Rf-restorer gene Shaan 2A CMS line
2014/2/25
Until now in Europe has not been cultivated any hybrid cultivar of oilseed rape based on the Shaan 2A cytoplasmic male sterility (CMS), a widely used CMS system in China. The aim of Czech breeders now...
Sterility of Thermo-Sensitive Genic Male Sterile Line,Heterosis for Grain Yield and Related Characters in F1 Hybrid Rice (Oryza sativa L.)
Dry matter F1 hybrid Grain yield Heterosis Sterility
2009/7/28
The thermo-sensitive genic male sterile (TGMS) T29s line was sterile when exposed to daily mean temperatures of 24.1°C or above during the critical stage (from 15 to 11 days before heading). It was co...
花椰菜细胞质雄性不育基因特异PCR标记的筛选Identification of PCR markers associtated with cytoplasmic male sterility in Brassica oleracea var botrytis
花椰菜（Brassica oleracea var.Botrytis） 细胞质雄性不育 CMS 候选基因
2008/1/10
摘要
基于同源序列的候选基因法(homology-based candidate gene method)，通过检索NCBI核酸及蛋白数据库，获得细胞质雄性不育（cytoplasmic male sterility CMS）相关的基因或开放读码框。生物学软件分析，根据保守区设计5对特异引物，PCR扩增，其中引物P9/P10在花椰菜细胞质雄性不育系knxd612中特异扩增出313 bp的片段。单株...
