ORIGIN: The Agricultural Experiment Stations of Oregon, North Dakota, California, Idaho, and Washington jointly released Modoc in 2003. Modoc was derived from a 1989 cross of ND1196-2R and ND2225-1R performed at North Dakota State University.
CHARACTERISTICS: Modoc is an early maturing, red-skinned, white fleshed potato cultivar for fresh market use. The Agricultural Experiment Stations of Oregon, North Dakota, California, Idaho, and Washington jointly released Modoc in 2003. Modoc was derived from a 1989 cross of ND1196-2R and ND2225-1R performed at North Dakota State University. Modoc retains bright skin color in storage and is suited for marketing directly from the field or storage. It produces slightly lower total yield than Red LaSoda or Dark Red Norland, but higher marketable yield and more desirable tuber size and shape. Modoc tubers seldom exhibit growth cracks, secondary growth, hollow heart or other external or internal defects. Dry matter content of Modoc tubers is similar to Dark Red Norland and Red LaSoda (18.9% compared to 18.8% and 17.7%, respectively). Culinary quality of Modoc was rated equal to Dark Red Norland and Red LaSoda for boiling and microwaving preparation methods. Modoc tubers are similar to standard varieties in sugar, vitamin C, and glycoalkaloid (4.5 mg/100 g) concentration. Modoc foliage clearly expresses PVY symptoms and has not demonstrated high susceptibility to viral or fungal diseases during a decade of seed production and evaluation.
Plants:
Modoc vines mature slightly earlier than Red LaSoda, and are sensitive to metribuzin injury. Modoc is susceptible to most fungal diseases. Experience with seed increases indicate it is not particularly susceptible to virus diseases and expresses readily discernible foliar symptoms to PVY. It is susceptible to late blight foliar and tuber infection.
Tubers:
Modoc is an early maturing, red-skinned, white fleshed potato cultivar for fresh market use.
STRENGTHS & WEAKNESSES:
Modoc retains bright skin color in storage and is suited for marketing directly from the field or storage.
Modoc tubers seldom exhibit growth cracks, secondary growth, hollow heart or other external or internal defect
