Chino. 甘薯新品种金山679是以金山57和广薯87为亲本经杂交选育而成，表现高产、稳产、食味品质好。研究金山679的高产生理特性，结果表明：该品种在整个生育时期均维持较大的叶面积指数，保持较高的光合生产能力；同时块根库容大，接纳同化物质能力强，同化产物积累于块根的比例也较高。上述生理特性显示金山679具有较高的产量潜力，形成高产的生理基础。[著者文摘]

Inglés. A new sweet potato variety Jinshan679 was bred from the hybrid offspring of Jinshan 57 and Guangshu87. with high stable yield, good eating quality. The high - yield physiological characteristics of Jins- ban 679 were studied. The results showed that Jinshan 679 maintains a relatively high level throughout the whole growing period, therefore kept high photosynthetic production capacity. At the same time, the variety demonstrates stronger ability to accumulation with a higher sink capacity, and the ratio of assimilation production was higher in the tuberous roots. The variety had high resistance against drought. All the above showed the high - yield physiological basis and potential of the variety.
