Hybrid sterility is one of the major barriers to the application of wide crosses in plant
breeding and is commonly encountered in crosses between indica and japonica rice …

Two subspecies in rice, japonica and indica, have their own ecotypic traits. However,
reproductive barriers such as spikelet sterility in hybrid progenies between subspecies have …

Background The exploitation of useful genes through interspecific and intersubspecific
crosses has been an important strategy for the genetic improvement of rice. Postzygotic …

Hybrid sterility between Oryza glaberrima and O. sativa seriously hampers the introgression
of favorable genes from each other. In order to further understand this issue, identification …

Hybrid sterility is a serious barrier in the utilization of wild rice for breeding, but little is known
regarding hybrid sterility between the cultivated rice, Oryza sativa, and its wild relative, O …

Systematic characterization of genetic and molecular mechanisms in the formation of hybrid
sterility is of fundamental importance in understanding reproductive isolation and speciation …

Hybridization between Oryza sativa L. ssp. indica and 0. sativa ssp. japonica could produce
heterosis but various reproductive barriers existed. The barriers included embryo sac …

The partial sterility of hybrids between the indica and japonica rice subspecies of Asian
cultivated rice is a serious constraint for utilizing inter-subspecific heterosis in hybrid rice …

In hybrid rice (Oryza sativa L.) breeding, spikelet sterility is a barrier to attaining enhanced
heterosis in crosses between different groups or subspecies of rice. Our objective was to …

To further understand the nature of hybrid sterility between Oryza sativa and Oryza
glaberrima, quantitative trait loci (QTL) controlling hybrid sterility between the two cultivated …
