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...
Faithful chromosome segregation is required for both mitotic and meiotic cell divisions and is regulated by multiple mechanisms including the anaphase-promoting complex/cyclosome (APC/C), which is the...
The sulphonylurea herbicide monosulphuron ester sodium (MES) was first used to induce male sterility in rapeseed (Brassica napus L.). Nearly 100% male sterility was achieved after a single treatment...
In this study, an optimized Cry2Aa gene was obtained after codon optimization based on the preferred codons in rice. The novel fusion gene Cry2Aa# was designed by adding the sequence coding the signal...
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...
Approximately 8% of couples in the World have problem with offspring production.Male infertility, which is the reason of the half of reproduction failures, is connected with diminished sperm productio...
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...
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...
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...
The differences between male and female plants in the growth of one-year-old asparagus (Asparagus officinalis L.), yield and quality of spear in forcing culture were investigated. Female plants had hi...
The differences between male and female plants in the growth, development and quality of Japanese butterbur hybrids were investigated. Regarding total spike yield, male plants were superior to female ...
‘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...
