In this research, varietal characteris-tics of nine cabbage cultivars were compared, and the suitability of cultivars to be harvested by machine (YANMAR HC-10) were evaluated for three years. The varietal (genetic) effect and environmental effect on the uniformity of head weight, harvest injury rate and head cracking rate was then examined and the possibility of breeding for machine harvest suitability was verified. Varietal differences were observed in harvest injury rate and head cracking rate, but not in the coefficient of variation of head weight. This result suggested the possibility for improvement of varietal characteristics concerning harvest injuries and head cracking. 'YR-Fuyutaro' and 'Fuyukei 609' were considered to be the most suitable cultivars for machine harvest, because there were almost no harvest injuries or head cracking caused by the harvest machine. Varietal differences were observed in the morphological characters below the base of the head. However, it is still unclear whether these characters relate to harvest injuries. We will continue to research the morphological characteristics that relate to harvest injuries in detail, and develop excellent breeding material suitable for machine harvest.}, pages = {37--43}, title = {機械収穫に適したキャベツ品種の選定と特性の評価}, volume = {7}, year = {2008}, yomi = {ヨシアキ, ヒトシ and サトウ, タカノリ and カメノ, タダシ and スズキ, トオル and ハタケヤマ, カツノリ and イシダ, マサヒコ} }
