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 Jinshan 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.
