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...
Bactrocera zonata, a serious pest of fruits in many parts of the world, has recently been recorded in Northern Africa. Even though it has not been introduced to the European continent yet, a strong ...
Two self-sterility systems, self-incompatibility (SI) and cytoplasmic male sterility (CMS) were used to verify their suitability for hybrid breeding of cauliflower. The possibility of reproduction of ...
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...
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...
Potted rice plants were grown in the phytotron with different water temperatures in a range from 18 to 25°C during the period from the spikelet differentiation stage to just before the young microspor...
Cooling treatments at different stages of pollen development lowered the percentage of fertilized spikelets through decreasing the number of engorged pollen grains per anther at anthesis. Cooling duri...
Induction of male sterility in rice by application of ethephon or isourea at different treatments, concentrations and times was investigated in glass house-grown Oryza sativa cv. Nipponbare. Isourea ...
We divided the developmental processes from microspore differentiation to fertilization into 4 phases and defined the component relating to fertilization in each phase. The percentage of fertilization...
‘Sweet Pepper Parental Line Nou-1’ was selected from a cross between a male sterile plant of ‘Tokyo Piman’ and ‘101(2·4)-11-1-4’ (a seed parent line of ‘Beruhomare’). The cross shows genic male steril...
To clarify the origin of local radish variety ‘Sabaka’ in Kyoto prefecture, the presence and variations of mitochondrial male-sterile gene (orf138) and the fertility restorer gene, orf687, were invest...
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...
摘要雄性不育的研究对于杂种优势的利用具有重要意义。本文综述了小麦雄性不育遗传及基因定位研究进展,介绍了小麦雄性不育的基因工程,对小麦雄性不育的应用进行了讨论。 Abstract:The study of plant male sterility plays an important role on utilization of heterosis.This paper reviews the c...
