Okikogane: New Sweetpotato Cultivar for Cooking Material and Food Processing

摘要

"Okikogane", developed by the National Agricultural Research Center for Kyushu Okinawa Region, is a newly released cultivar for cooking material and food processing. It was evaluated in prefectural agricultural experiment stations as breeding line "Kyushu No. 147", and was officially registered as "Sweetpotato Norin No. 61" by the Ministry of Agriculture, Forestry and Fisheries in 2004. "Okikogane" is a progeny from a cross between "Beniwase" and "Satsumahikari" performed at the Ibusuki branch of thestation in 1984. A total of 67 seeds were sown in the Sweetpotato Breeding Laboratory nursery, and selected based on good field performance and low brix of cooked root. "Beniwase" is a cultivar suitable for early planting and harvesting for table use. "Satsumahikari" is a non-sweet cultivar lacking bate-amylase activity for food processing.
