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...
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...
Flower opening in the early morning helps avoid sterility induced by heat stress at anthesis in rice (Oryza sativa L.). A pot experiment was conducted to reveal the effects of methyl jasmonate (MeJA) ...
Effect of the starting time of cooling at the flowering stage together with the effects of water temperatures and light conditions after cooling on the fertility percentage were examined. The fertilit...
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...
Rice pollen grains germinated more than 80% with low variation (standard deviation less than 10%) and their pollen tubes elongated to more than 150μm within one hour with a simple medium composed of 1...
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...
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...
Sterility was induced by low temperature at the booting stage in early maturing varieties in 1986, and in medium and late varieties in 1987, particularly in the varieties without cool tolerance at Hok...
In rice plants a drought at the booting stage is the event most damaging to grain yield because it drastically increases sterility. Our objective was to establish what phosiological processes caused s...
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...
Although the impact of anticipated global warming on regional rice production merits intensive investigation, quantitative information regarding the effects of high temperatures on japonica rice is li...
Does Regional Temperature Difference before the Panicle Initiation Affect the Tolerance for Low Temperature-Induced Sterility in Rice?
