Research on Technology and affect of mini potato with no virus high-speed Reproductin

In potato main producing region Kesh an county,Heilongjiang Province,t o take Keshan new kind No.4tube breeding with no virus as material,carry an experiment of mini -potato hi gh -speed reproduction.In the lab,f ast the reproducing speed by way of simpliaing training radix and liquid trainin g radix,reducing the cost;In worm defend shed,fast the basic breeding speed b y way of tip -cutting and perch -interposing 40days later,add pp 333 and adjust temperature in days and nights ,this can improvethe output of mini -potato with no virus at the same time.To exa mine the growing condition 60-80days later.The experiment prove that seed potato is big,the output is high,60%bi g,middle,mini seed potato with no viru ss tuber is more than 50gram,this pr ove mini potato with no virus has good producing potential.
