1. Abnormal climate is often one of the main causes of farmers planting the crop failure. In recent years， climate change， the production of crops were especially caused loss by temperature and rainfall changing.Potato was mainly planted in winter in Taiwan. Anomalous Climate in recent years， such as low temperature of climate anomalies was often associated with rainy. Those factors leaded to the potato corruption and induced more diseases. Especially large-scale production problems caused by late blight， so growers often need to spraying pesticides to control and increase the burden. In addition to affecting farm income，it also result in increased production costs， food safety and market price volatility and other issues. Therefore， in order to improve a variety of problems by low temperature and high wet， we have been improved varieties by the goal. We select excellent growth potential，yield and quality of 48 clones after years of breeding， and we select and assess by low temperature and high humidity for 48 clones.。2. Those clones were selected on 2009 to 2010， the 11 clones were primaries selected with wet tolerance and high yield characteristics of growth (628、474、470、91A179、320、183、578、91N80、317、T75、462). We continued to select to 5 clones (number of clones: 470、628、91N80、 320、462) on 2010 to 2011. Those clones have wet tolerance， excellent growth， high yields and medium or high disease tolerance characters. We assessed the best of three clone which are 628， 470 and 320. We will prepare to conduct characters of investigations， and select of the best performing clones by overcoming low humidity high temperature. We hope to help the seed industry overcome abnormal environment with reduction of output and excessive using of pesticides， influence food security，farmers' health and other issues。
