7个日本南瓜品种引种比较试验

为筛选适宜广西栽种的日本南瓜品种,2009～2010年对7个从日本引进的南瓜品种进行生长势、抗病性、果实商品性及感官品质比较试验。结果表明,萨摩えびす和えびす生长势中或强,高抗白粉病,瓜形美观,果实大而均匀,肉质致密,口感、风味俱佳,适宜在广西各地大面积推广种植;栗坊、栗みゃこ、栗えびす瓜形美观,口感、风味俱佳,但瓜型偏小,产量低,不适宜大面积推广种植;味一番高抗白粉病和病毒病,可作为抗病育种材料;红姬口感超粉、甜,具特殊清香味,但生长势弱,瓜型偏小,不耐低温,不适宜大面积推广种植,可作为优良种质资源加以保存利用。

A comparative evaluation or seven pumpkin varieties introduced from Japan

The present experiment was conducted to screen Japanese pumpkin varieties suitable for planting in Guangxi.Seven pumpkin varieties introduced from Japan were planted to compare the plant growth vigor,resistance to powdery mildew and viruses,and commercial quality of the fruit.The varieties Samma Ebisu and Ebisu showed strong to moderate growth vigor,high resistance to powdery mildew,beautiful and uniform fruit appearance,wonderful flesh texture,taste and larger size of the fruit.These two varieties were suitable for planting in large scale in Guangxi province.Two varieties,viz.,Kuribou,Kurimyako and Kuriebisu had good fruit appearance,flesh texture and taste,but due to smaller fruits and lower yield,these are unsuitable for planting in large scale in Guangxi.The variety Ajiyichiban recorded high resistance to powdery mildew and virus diseases,and could be used as the breeding material for developing resistant varieties.The variety Akehime had sweet taste with special faint scent,but it showed weak growth vigor,small fruits and weak resistance to low temperatures.Though,it was not suitable for planting at large scale but recommended for keeping as a germplasm resource.
