Abstract: The paper aims to study the dynamical development regularity and correlation of tuberization traits of potato. The authors observed the development dynamic and correlation with yield per plant(YP) of the plant height(PH), stolon length(SL), root length(RL), primary stolons(PS) and mini-tubers(MT) of C×E population in aeroponic. The results showed that there was obvious segregation beyond the two parents for five agronomic traits among F1. It was the major developmental stage of root during the 40 d after the transplantation. Plant height of the potato grew rapidly from 50 d to 70 d after the transplantation. Primary stolons emerged rapidly from 30 d to 50 d after the transplantation and reached its peak at 60 d. Stolons length mainly grew from 40 d to 50 d after the transplantation and the mini-tuber also began to swell. Correlation analysis showed that MT had significantly or highly and significantly positive correlation with SL, and MT had highly and significantly positive correlation with PS. YP had highly and significantly positive correlation with PS. So, SL and PS are two important factors for screening the fine individual genotype of potato for aeroponic.
