US: Potato Board Chip Committee funds Zebra Chip Variety Research

Dr. Creighton Miller from Texas A&M University has been working with the United States Potato Board (USPB) varieties and the Zebra Chip defect. Dr. Miller is developing a variety testing process to help identify varieties with tolerance to the Zebra Chip Defect. In his first year doing this work for the USPB, it appears three varieties are showing more tolerance to obtaining the Zebra Chip Defect than others. The varieties showing tolerance in our initial testing are the following: MSL 292-A (Manistee), W2717-5 (Lelah), and W2324-1 (Accumulator). Other varieties that were tested but did not display a high a level of tolerance include: Atlantic, Snowden, W5015-12, MSH228-6, Lamoka, Nicolet, and NY138 (Waneta). It is the plan of the USPB Chip Committee to continue this work to see if varieties can be identified which display consistent resistance to the Zebra Chip Defect. If varieties with consistent tolerance can be identified, it may provide suppliers with another method of reducing the impact of this complex defect. (Source: USPB)
