Bekoaoba is a new rice cultivar suitable for whole-crop silage (WCS) developed at the National Research Center for Tohoku Region and registered as "Norin 408" by the Ministry of Agriculture, Forestry and Fishery (MAFF) in 2005. It was selected from progeny of a cross of Oochikara and Saikai 203. "Bekoaoba" is a cultivar classified as a middle-to-late group. It has a short, fat and stiff culm, and high lodging tolerance. "Bekoaoba" has a true resistance gene to blast, "Pita-2", while resistance to leaf blast and panicle blast were slightly low and low, respectively. The grain yield of "Bekoaoba" was almost the same as that of "Kusayutaka"．The size of the brown rice is extremely large, so "Bekoaoba" can be distinguished from eating rice. In direct seeding cultivation, lodging tolerance is evidently superior to "Kusayutaka" and "Fukuhibiki", so "Bekoaoba" is suitable for direct seeding cultivation. The yellow-ripe stage of "Bekoaoba" is earlier than that of "Kusayutaka", and the TDN yield of "Bekoaoba" is about 10% higher than that of "Fukuhibiki" and "Yumeaoba". Adaptability for heavy manuring is high, and there is no lodging under heavy manuring conditions using livestock manure compost. "Bekoaoba" is available for rice whole-crop silage in the Tohoku region and is suitable for resource cycling agriculture using livestock manure compost in cooperation with rice agriculture on a stock farm.
