【摘要】 <正> 吉林省东部为长白山区,中部为松辽平原,西部为广阔的风砂平原,蕴藏着丰富的野生与栽培抗寒果树种质资源,是我国也是世界上抗寒果树种质资源的宝库。解放后,吉林省农业科学院曾进行了抗寒果树种质资源的调查、搜集、保存、研究与利用,先后共调查整理了野生与栽培果树种质资源12科、22属、66种、25变种、24变型、688品种。本文将三十余年来对抗寒果树种质资源的研究与利用情况介绍于下。更多还原

【Abstract】 Jilin Province is located in the middle region of Northeast of China with severe cold climate, but rich in fruit germplasm resources with cold resistance. The exploration, collection, conservation, investigation and utilization of such germplasmr esources have been carried out both in cultivated and wild fruit plants since 1949.The fruit germplasm resources belong to 12 families, 22 genera, 66 species, 25 varieties, 24 formae and 688 cultivars. The results of investigation and utilization of fruit germplasm resources with cold resistance for more than 30 years are reported in this paper. By using these valuable hardy fruit germplasm resources in breeding of cold resistant fruit trees, the poor harvest situation of apple, pear, grape and other fruit trees has been greatly changed. However, there is still a vast potential of fruit germpiasm resource to be tapped in this area.更多还原
