甘薯种质资源是甘薯育种的宝贵财富。为了充实甘薯的基因源,近几年来从国内外征集了甘薯品种、品系、种籽和近缘野生植物。1977年至1982年共征集到农家种382份,杂交种44份,国外种50份以及甘薯近缘野生植物19份。连同原来保存的材料合计农家种469份,杂交种88份,国外种81份。加上美国集团选择后代群体的选系200余份,总计近800余份。1980—1982年对这些资源材料,以
Sweet potato germplasm resources is a valuable treasure of sweet potato breeding. In order to enrich the gene source of sweet potato, in recent years, sweet potato varieties, strains, seeds and relatives wild plants have been collected from home and abroad. From 1977 to 1982, 382 farm families, 44 hybrids, 50 foreign species and 19 wild relatives of sweet potato were collected. Together with the original preserved materials, there were 469 farmer species, 88 hybrids and 81 foreign species. In addition, the U.S. group has selected more than 200 selected groups of offspring for a total of nearly 800 copies. 1980-1982 on these resource materials, with
