Atlantic is the standard variety for chipping from the field or very short-term cold storage. It has traits desired by the chip industry such as uniformity, high specific gravity and high yield. However, Atlantic tubers are susceptible to common scab and internal defects such as internal brown spot, black spot bruise and hollow heart. In addition, Snowden is the standard variety for cold storage; however, it also suffers from internal defects. In contrast, Superior has been reported as resistant to common scab and internal defects. Previous studies in our program revealed that Superior has much higher tuber calcium concentration as compared to Atlantic and Snowden. FI segregating populations have been generated from a reciprocal cross between Atlantic x Superior and the cross between Superior x Snowden. These populations were evaluated for specific gravity, yield, common scab and internal quality for two seasons at Hancock, WI. Some of the best performing clones have also been evaluated at several locations under the National Chip Processing Trials including Wisconsin, North Carolina, Texas, California and Florida. The objective of these evaluations is to identify promising clones that perform as good or better than Atlantic. Our preliminary results suggest that among our populations there are some clones with characteristics of commercial interest that can be used as new varieties and/or as parents of future populations in our breeding program.
