国外引进野生苦瓜资源的性状调查研究

Investigation and Evaluation on the Wild Material Characters of Bitter Gourd abroad

对引进的多美尼加野生苦瓜资源主要性状进行了调查、研究,结果表明,野生苦瓜晚熟,叶小茎细,长势旺盛,侧蔓结果为主;果绿色,纺锤形,密布刺瘤,味苦;对白粉病,枯萎病的抗性达到高抗甚至免疫;耐热性、耐寒性远强于栽培种,在抗病和抗逆育种中具有很高的利用价值,但其缺点是果小,肉薄、韧而不堪食。

The main characters of a wild bitter gourd from Dominica were investigated and evaluated in order to utilize the special disease-resistant genes to solve the serious main diseases in the bitter gourd production in China.
