Kitachikara is a single cross hybrid between two dent inbred lines, Ho68 as seed parent and GY302 as pollen parent. Kitachikara is classified into the medium maturity group and is adapted to temperate parts of the northern-central region, central Tokachi and inland areas of Abashiri in Hokkaido. The silking date of Kitachikara is four days later than that of Royal-dent 90H. Whole plant dry matter content of Kitachikara is higher than that of Royal-dent 90H. The average yield of Kitachikara is the same as that of Royal-dent 90H for ear dry matter, 13% higher than that of Royal-dent 90H for stover dry matter, and 6% higher than that of Royal-dent 90H for whole plant dry matter. Ear content of Kitachikara is 3.5% lower than that of Royal-dent 90H on average. Kitachikara has a high level of lodging resistance, the percentage of lodged plants being similar to that of Royal-dent 90H and lower than the percentages of other cultivars in the same maturity class. Kitachikara shows a moderate level of resistance to northern corn leaf blight (Setosphaeria turcica) and southern corn leaf blight (Cochliobolus heterostrophus). Its level of resistance to northern corn leaf blight is a little higher than that of Royal-dent 90H and higher than that of Kitayutaka. Its level of resistance to southern corn leaf blight is higher than the levels of resistance of Royal-dent 90H and Kitayutaka. Kitachikara shows a level of resistance to common smut (Ustilago maydis) similar to that of Royal-dent 90H. Cold tolerance of Kitachikara is the same as that of Royal-dent 90H and a little lower than that of Daiheigen. Suitable planting density of Kitachikata is 800 - 850 plants per are, and the adaptability of Kitachikara to higher planting density is as high as that of Royal-dent 90H.}, pages = {1--44}, title = {サイレージ用トウモロコシの耐倒伏性・茎葉多収品種「きたちから」の育成}, volume = {186}, year = {2006}, yomi = {コイヌマ, ケイイチ and ミウラ, ヤスオ and ミキ, カズヨシ and エノキ, ヒロユキ and サトウ, ヒサシ} }
