苦瓜新品种引进比较试验

为筛选出适合海南屯昌地区种植的苦瓜优良新品种,通过引进全国8 个优良苦瓜新品种对其农艺性状、抗病性抗逆性和产量等方面进行了比较研究结果表明院中华一号和桂农科1 号苦瓜的综合性状表现良好，小区产量分别为43.30,43.23 kg折合每公顷产量33 324.30 kg 和33 270.45 kg比枫木苦瓜CK分别增产16.43%和16.24%其他参试品种也表现较好产量均极显著高于枫木苦瓜CK因此，中华一号和桂农科1 号苦瓜在农艺性状抗性和产量等方面均表现较佳较适合海南冬季种植可进行大面积示范推广。

Comparative test of introduction of new bitter gourd varieties

Eight new and fine bitter gourd varieties were selected from nationwide to screen suitable varieties forplanting in Tunchang county, Hainan. Comparative field experiments were carried out, and agronomic characters, diseaseresistance, stress resistance and yield of each variety were investigated and compared. The results indicated that Zhonghua1 and Guinongke 1 showed good comprehensive traits, their plot yields were recorded as 43.30 kg (33 324.30 kg/hm2) and43.23 kg (33 270.45 kg/hm2) respectively, increased by 16.43% and 16.24% over control. The other varieties also showedgood comprehensive characters, their yields were significantly higher than that of control. Thus Zhonghua 1 and Guinongke1 performed better in agronomic characters, resistance and yield, were appropriate for winter planting and could beextended for demonstration in Tunchang county.
