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...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants : XXIX. The mechanism of enhancement in cool tolerance by raising water temperature before the critical stage
Cool injury Cool tolerance Microspore Pollen Rice Sterility Water temperature
2009/8/6
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...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXX. Relation between fertilization and the number of engorged pollen grains among spikelets cooled at different pollen developmental stages
Anther Cool injury Cool temperature Microspore Pollen Rice Sterility
2009/8/6
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...
Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXXI. Four components participating in fertilization
Cooling injury Cooling tolerance Fertilization Microspore Pollen Rice
2009/8/5
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...
Breeding‘Sweet Pepper Parental Line Nou-1’with Genic Male Sterility
breeding materials phytophthora blight resistance seed production ToMV resistance
2009/7/8
‘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...
Origin of Local Radish Variety,‘Sabaka’,in Kyoto Prefecture Inferred by Analyses of Genes for Cytoplasmic Male-sterility and Fertility Restoration
