Generally, two hybridization events have happened in the generation of gynogenetic crucian carp: the first one occurred about 6, 000 years ago when maternal ancestor of C. a. gibelio hybridized with males of C. a. auratus (ancestor of C. a. colored variety) and a diploid hybrid was produced; the second one happened over 10, 000 years ago, when the diploid hybrid was backcrossed with one of its parental population, by which the current triploid gynogenetic crucian carp emerged.
初步推断出东北雌核生殖银鲫是通过鲫鱼种群间的两次杂交产生的,第一次杂交是母本的银鲫同源种群与父本的彩鲫同源种群杂交,形成二倍体杂种;第二次杂交是二倍体杂种与两个祖先鲫鱼种群之一回交,形成了今天的三倍体杂种银鲫。

He not only is our country hybrid rice research founder, also is the our country hybrid rice research chief designer and the most main leaders in a scholarly field. In 1986 he proposed the hybrid rice breeding from three is the law to two is the law to one is the law and uses three development phases from the variety to the subspecies to 远缘杂种 the superiority the strategic tentative plan, this tentative plan has become the domestic and foreign recognitions hybrid rice breeding the guiding ideology.
他不仅是我国杂交水稻研究的开创者,也是我国杂交水稻研究的总设计师和最主要的学术带头人。1986年他提出杂交水稻育种由三系法到两系法到一系法和从品种间到亚种间到远缘杂种优势利用三个发展阶段的战略设想,这一设想已成为国内外公认杂交水稻育种的指导思想。1987年两系法杂交水稻技术被列为国家&863&计划的重点课题。

Large supply of non-hybrid seeds for vegetables, grains and herbs; make sure they are of the non-GMO, non-hybrid, propagating variety; also be sure to have instructions on how to harvest seeds including information on "moldering" techniques to properly collect seeds from certain plants such as tomatoes; note lastly that due to damp low-sunlight conditions many crops will not grow without growing lights and protection from rain; special research is therefore required on which crops will grow best (for instance, patty rice should grow better than wheat under damp conditions); also be sure to take into account the climactic change which results from the change in latitude due to the pole shift as a location which does not change greatly in latitude will fare better than one which falls in the vicinity of the new poles for instance; the pole shift theory presented on Zeta Talk states that the terrestrial North Pole will move to the middle of the Atlantic off the bulge of Brazil and ultimately one will need to observe the climate and the position of the sun to figure out the new latitude, and either adapt or re-locate as needed
要有许多蔬菜,谷物和草药的的非杂交种子;确信它们是非转基因,非杂交的,是用于繁殖的品种。也得确信具有怎样收获种子的指导书说明,包括&制造&技术方面的信息,以便恰当地收集某些植物的种子,例如西红柿。最后得注意,由于幽暗的低阳光环境,在没有阳光,以及没有其进行雨水防护的情况下庄稼将不会下生长。因而需要进行特别的研究,看看哪种庄稼在这种条件下生长得最好(例如,在昏暗的状况下,水稻应该比小麦生长的更好)。也要确信考虑了极移造成纬度改变,因而导致气候变化。例如,与那些位于新极点附近的地方相比,纬度变化不特别大的地方情况要好得多。齐塔人之声讲述的极移理论表明了地球北极会移动到大西洋中部的巴西隆起处。最后需要观察气候状况以及太阳的位置,以弄清楚新的纬度,根据需要,即可适应当地的条件,又可再次搬迁。
