Abstract
種間における交雑歩合は, 花粉及び雌蕋の能力が温度その他の条件によるためか, 現在迄の報告は結顆歩合が低く, また種々別々である, 即ち種間交雑難易の比較またその原因を探求しようとするために行われた圃場試験結果には無理がある。よつて花粉管伸長及び雌蕋機能の最適温度20°Cにおいて, 実験室内において子房内に花粉管の伸長する歩合を以つて結実とみなし比較検討した。A. moschata×Pepo 26.2%moschata 種の品種内において会津系品種を母とした場合の方が干潟系を母とする場合より歩合が高い。B. Pepo×moschata 20.5%Pepo 種の品種内において有蔓系品種を母とした場合の方が無蔓系品種を母とする場合より歩合が高い。C. Pepo×maxima 29.4%Pepo 種の品種内においてはBと同様。D. maxima×Pepo 37.5%maxima 種の品種内においては Delicious 系品種を母とした場合の方が Hubbard 系品種を母とする場合より歩合が高い。E. maxima×moschata 40.5%maxima 種の品種内においてはDと同様。F. moschata×maxima 77.4%moschata 種品種内においても干潟系を母とした場合方が会津系を母とする場合より歩合が高い。種間におる交雑親和力は種によつて大きな異を齎し, 種内においても, 品種系統により明かに親和力大小を認める。
