Predicted climate changes, in particular, the increased dimension and frequency of heat waves, are expected to affect crop growth in the future seriously. Hybrid rice relies on seed production from male sterile and restorer lines. Experiments were conducted over two consecutive years to compare the high temperature tolerance of parents of different hybrid rice combinations, in terms of fertilit...

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...

HREE different kinds of hybrid sterility of males occur within the superspecies Drosophila ptzulistorum Dobzhansky and Pavan, and a fourth one will he described in the present paper. The superspecies consists of at least five races or incipient species (DOBZHANSKY and SPASSKY 1959). The F, hybrids between these races are fertile if females and sterile if males. This is a sterility of the genic ...

The Aegilops kotschyi thermo-sensitive cytoplasmic male sterility (K-TCMS) system may facilitate hybrid wheat (Triticum aestivum L.) seed multiplication and production. The K-TCMS line is completely male sterile during the normal wheat-growing season, whereas its fertility can be restored in a high-temperature environment. To elucidate the molecular mechanisms responsible for male sterility/fer...

The release of genetically-modified or sterile male mosquitoes offers a promising form of mosquito-transmitted pathogen control, but the insights derived from our understanding of male mosquito behaviour have not fully been incorporated into the design of such genetic control or sterile-male release methods. The importance of aspects of male life history and mating behaviour for sterile-male re...
