Abstract：Using virus-free seedlings of the new drought-resistant and high-starch processing potato variety Mengwushu No.6 as experimental material,this study investigated the effects of different culture vessels on the growth of variety virus-free seedlings,screened the effective concentration of Yipeilong bacteriostatic agent for bacterial contamination control,and explored the suitable induction method for container potato of this variety.The results showed that the virus-free seedlings in the fully automatic plastic square box were more robust,with improved photosynthetic efficiency and stronger growth potential.This treatment could increase the multiplication coefficient of potato virus-free seedlings,which was superior to the glass bottle culture.The most suitable concentration of Yipeilong for preventing bacterial contamination in Mengwushu No.6 was 0.20％.The rapid induction culture method for in vitro potato tubers is as fol-lows:Solid medium(seedling-strengthening stage:MS+30 g·L-1 sucrose+6 g·L-1 carrageenan)+liquid medium(container potato induction stage:MS+80 g·L-1 sucrose+500 mg·L-1 chlormequat chloride+5 mg·L-1 6-benzylaminopurine).The re-sults of this study not only lay a technical foundation for the industrialization development of Mengwushu No.6,but also provide a reference for research on similar potato variety.
