| Research Abstract |
Potato plants are week for drought stress because of its small root mass and less extension to deep soil layers. To enhance the improvement of root system in potato breeding, we examined the difference in root mass in a diploid CxE population introduced from the Netherlands and detected a effective QTL for root mass at Chromosome 5. The root mass showed highly correlations with plant earliness and early tuber bulking, of which QTLs were located at the same position of root QTL.
