半个世纪以来,世界各国十分重视国外植物种质资源的研究和利用,在育成的品种中,大多数是利用地理远缘的优良基因。我国已分别从70个国家和地区,征集了约万份小麦品种(品系)及小麦近、远缘植物。黑龙江省近二十年来,引入了大量的国外小麦种质资源,改变了本省原有小麦亲本血缘单一的状况,已在小麦生产和小麦育种工作中发挥了重要作用。
For half a century, all countries in the world attach great importance to the research and utilization of plant germplasm resources abroad, and most of the cultivated varieties are excellent genes that make use of geographical distantness. China has collected about 10,000 wheat varieties (strains) and wheat near and far plants from 70 countries and regions. In the past two decades, Heilongjiang Province introduced a large number of foreign wheat germplasm resources and changed the single blood condition of the original wheat parents in the province, which has played an important role in wheat production and wheat breeding.
