Abstract: | TheMaineChip potato variety is medium-maturing and has round, whiteskinned, white-fleshed tubers with shallow eyes, high specific gravity and moderate yields. Its major use is expected to be as a storage chipping variety since sugar build-up in storage is slow, and reconditioning is possible. This variety can be chipped directly from 7 C storage.MaineChip does not show the net necrosis caused by potato leafroll virus and is moderately tolerant to verticillium wilt (Verticillium alboatrum) and rhizoctonia (Rhizoctonia solani). It is also moderately resistant to blackspot and shatter bruise. Hollow heart is its major internal quality defect, being a problem in ten of the twenty-nine regional tests conducted over five years. |
