１９８７－１９９２年选用优亲配制组合进行复合杂交，育成甘薯新品种金山５７，１９９３年通过专家技术鉴定和福建省农作物品种审定委员会的审定．该品种表现特早熟、高产、优质、抗病、耐旱及耐寒力较强和适应性较广等综合优良性状，尤其抗蔓割病、群Ⅰ薯瘟病、黑腐病和根腐病等多种病害，并较好地解决了高产与优质和高产与早熟难以兼顾的矛盾，是福建省“六五”以来甘薯育种攻关的一个突破．金山５７推广速度快，１９９１年全省示范种植面积９２６．７ｈｍ２，１９９２年示范推广１３８６６．７ｈｍ２，１９９３年全省６地市、３８县（市）区扩大推广４２２００ｈｍ２，１９９１－１９９３３年累计推广面积５６９９３．４ｈｍ２，增产薯干１４．６万ｔ，增加产值１．４７亿元。
In 1987-1992, the elite sweet potato combination was selected for composite cross breeding, and the new sweet potato variety Jinshan 57 was bred. In 1993, it passed the expert technical appraisal and the approval of the Fujian Crop Variety Approval Committee. The variety showed special precocious, high yield, high quality, disease resistance, drought tolerance and strong cold tolerance and wide adaptability and other comprehensive fine traits, especially anti-fumigation, group Ⅰ blast, black rot and root rot more And resolves the contradiction between high yield and high quality, high yield and precocious puberty. It is a breakthrough in the key research of sweet potato breeding in Fujian Province since the “Six Five”. Jinshan 57 to promote speed, in 1991 the province demonstration planted area of 926.7hm2, 1992 display promotion 13866.7hm2, the year of 1993 six provinces and municipalities, 38 counties (cities) to expand the promotion area 42200hm2, 1991-19933 56993.4hm2, an increase of 146,000 tons of dried potato, an increase of 147 million yuan output value.
