“IRRI”(国际水稻研究所)的水稻种质库,现今收集和保存有三万四千多份种质材料,几乎每个种质材料都有品种起沅、种子来沅以及37个遗传性状的部分或全部介绍;有一万七千多个杂交种都附有另外37个农艺形态特征的详细描述。这样庞杂的资料,研究者如何才能运用自如?“IRRI”自1972年以来,配制了一万七千多个品种间杂种,这些杂种的系谱史是育种学家进行育种的必需工具,他们怎样才能记住如此错综复杂的系谱?1975年,将近有八万三千份水稻原种材料送往世界各地,供国际水稻试验计划组织十二个育种场的四百五十七个点进行试验和筛选。
Rice genebanks at “IRRI” (International Rice Research Institute) now collect and preserve more than 34,000 germplasm materials. Almost every germplasm has its own variety, Yuanlai, Yuanlai and 37 genetic traits Part or all of the introduction; more than 17,000 hybrids are accompanied by a detailed description of 37 additional agronomic features. How can researchers use this complex information? IRRI has produced more than 17,000 interspecific hybrids since 1972. The pedigree history of these hybrids is an essential tool for breeders to breed. How can they Remembering such intricate pedigree? In 1973, nearly 83,000 rice seed materials were sent around the world for testing and screening at 477 points of 12 breeding farms by the International Rice Pilot Project.
