The original vine of ‘Grosz Krone’ was initially selected in 2002 in a vineyard at Akitsu, and was tested as selection Budou Akitsu 30 under the 13th Grape Selection National Trial initiated in 2010. It was released as ‘Grosz Krone’ in 2017, then registered as No. 28086 under The Plant Variety and Seedling Act of Japan in 2020. The vine vigor is strong. Sprouting and flowering times are 1 day and 2 days later than ‘Kyoho’ in the national trial. Time taken to trim flower clusters was the same as ‘Kyoho’, but that to trim berries is shorter than ‘Kyoho’. Harvest time of seedless fruit is the same as ‘Kyoho’ but 4 days earlier than ‘Pione’. Berry weight averages 19 g, larger than ‘Kyoho’ and ‘Pione’ in seedless fruit production. Soluble solids concentration averages around 18.4 %, similar to those of ‘Kyoho’ and ‘Pione’. Titratable acidity averages 0.46 g/100 ml, significantly lower than that of ‘Kyoho’. Flavor is foxy. Berry skin cracking sometimes occurs depending on years and locations. Seedless berries can be produced by GA treatment, but streptomycin treatment before anthesis is needed for complete convert to seedless berries. Berry skin color is attractive purplish black. Berry skin shows good coloration compared to ‘Kyoho’ and ‘Pione’ even in warm region of south west districts in Japan. Therefore, ‘Grosz Krone’ is expected to be a suitable cultivar for adapting to warmer climate., ‘グロースクローネ’は,1998年に‘藤稔’に‘安芸クイーン’の交雑を行い,そこから得た実生から選抜された,紫黒色の大粒ブドウである.2010年からブドウ第13回系統適応性検定試験に供試し,2017 年2 月の果樹系統適応性・特性検定試験成績検討会で新品種候補にふさわしいとの合意が得られ,2020 年8 月14 日に第28086 号として種苗法に基づき品種登録された.樹勢は強い.発芽期は‛巨峰’より1日,開花期は‘巨峰’より2日遅い.満開~満開3日後と満開10~15日後にジベレリン25ppmに花(果)穂を浸漬処理することにより無核果生産できるが,安定した無核果生産にはストレプトマイシンの利用が望ましい.花穂整形労力は‛巨峰’並み,摘粒労力は‘巨峰’より少ない.果実成熟期は‘巨峰’とほぼ同時期であり,‘ピオーネ’より4日程度早い.果粒重は19 g程度,糖度は18.4%程度,酸含量は0.46g/100ml程度である.裂果性は‘巨峰’や‘ピオーネ’よりやや多い.無核栽培における含核数は0.10個/粒で,‘巨峰’と同程度である.果皮色は紫黒色で,気温が高い夏秋季の西南暖地においても‛巨峰’や‘ピオーネ’と比較して安定して良好な着色が得られる.高温下でも着色が容易なため,‛巨峰’や‛ピオーネ’において着色不良が発生しやすい西南暖地での普及が見込まれる.}, pages = {47--61}, title = {ブドウ新品種‘グロースクローネ’}, volume = {7}, year = {2021}, yomi = {サトウ, アキヒコ and ヤマダ, マサヒコ and ミタニ, ノブヒト and コウノ, アツシ and バン, ユウスケ and ウエノ, トシヒト and シライシ, ミキオ and オノウエ, ノリユキ and イワナミ, ヒロシ and アズマ, アキフミ and ヨシオカ, ミカノ and マセ, ノブコ and イトウ, タカオ} }
