the possibility of occurrence of some rearrangements inside and or around coxii and atp6 genes and their relationship with male sterility in rice lines having wild abortive (wa)  cytoplasm was studied. two sterile (ir58025a and ir62829a) and two maintainer lines (ir58025b and ir62829b) were used. radioactive southern blotting was employed to carry out the experiments. the hybridization of coxii...

exploitation of the full potential of any hybrid requires the possessing of genetically high-purity seeds. commercial soybean hybrids have been developed using a cytoplasmic male sterility (cms) system. in order to avoid reduction in yield caused by using low-purity seeds, development of a simple, rapid, and accurate method for hybrid purity assessment is of great essence and significance. ther...

Male sterility plays an important role in the utilization of heterosis rice. The establishment male sterile lines rice is one key technologies hybrid production systems. currently widely used line breeding systems mainly include: three-line based on cytoplasmic sterility, two-line environmental sensitive gene and third-generation nuclear Seed system. This study reviewed types mechanisms rice, l...
