长沙地区南瓜品种筛选试验

Study on the Adaptions of Pumpkin Varieties in Hunan Province

为筛选出适于长沙地区种植的优质、高产南瓜新品种,本研究以17个印度南瓜品种和15个中国南瓜品种进行比较试验,对各品种的基本性状(第一雌花节位、始花期、瓜皮颜色、瓜形、瓜肉颜色、平均单瓜质量、可溶性固形物、单位面积产量等)进行测量、记录和分析。结果表明,绿皮类型的印度南瓜中“DN-1”、“菜用南瓜2号”和“中栗6号”品质表现较好,平均可溶性固形物分别为14.9%、14.6%和14.0%;“菜用南瓜2号”和“中栗3号”产量较高,平均每667 m^2产量分别为2457 kg和2135 kg。红皮类型的印度南瓜“京研7号”、“C19红杂2”和“红栗68”品质表现较好,平均可溶性固形物分别为13.5%、13.2%和12.5%;“京研7号”、“C19红杂1”和“红粟68”产量表现较高,平均每667 m^2产量分别为2492 kg、2261 kg和2121 kg。中国南瓜类型的“1号棒棒瓜”和“粉蜜1号”品质表现较好,平均可溶性固形物分别为12.6%和12.5%;“香蜜小南瓜”、“1号棒棒瓜”和“北蜜2号”产量较高,平均每667 m^2产量分别为3318 kg、3150 kg和3115 kg。研究认为,综合各供试南瓜品质及产量,推荐印度南瓜品种“菜用南瓜2号”、“中栗6号”、“DN-1”、“京研7号”、“红栗68”和中国南瓜品种“甜蜜小南瓜”、“1号棒棒瓜”、“金圆南瓜”在长沙地区推广种植。

In order to select the high-quality and high-yield pumpkin varieties suitable for planting in Changsha,a total of 17 Cucurbita maxima and 15 Cucurbita moschata varieties were tested and their performances were compared in this study.The traits including the first female flower node,initial florescence,fruit color,fruit shape,flesh color,fruit weight,soluble solid content,and yield were measured.The results showed that the C.maxima green-skin type varieties of“Caiyongnangua 2”,“Zhongli 6”and“DN-1”were better in quality,and their average soluble solid contents were 14.6%,14%and 14.9%,respectively.The same type varieties of“Caiyonglangua 2”,“Zhongli 3”had higher yields,and their average yields were 2457 kg and 2135 kg per 667 m^2,respectively.The C.maxima red skin type varieties of“Jingyan 7”,“C19 Hongza 2”and“Hongli 68”were better in quality,and their average soluble solid contents were 13.5%and 11.3%,respectively.The same type varieties of“Jingyan 7”,“C19 Hongza 1”and“Hongli 68”had higher yields,and their average yields were 2492 kg,2261 kg and 2121 kg,respectively.The C.moschata type varieties of“1 Bangbanggua”and“Fenmi 1”of were better in quality,and their average soluble solid contents were 12.6%and 12.5%,respectively.Among the same type varieties,“Xiangmixiaonangua”,“1 Bangbanggua”,and“Beimi 2”had higher yields,and their average yields per 667 m^2 were 3318 kg,3150 kg,and 3115 kg respectively.Taken together,the results showed that the C.maxima varieties of“Caiyongnangua 2”,“Zhongli 6”,“DN-1”,“Jingyan 7”,and“Hongli68”and the C.moschata varieties of“Tianmixiaonangua”,“1 Bangbanggua”,and“Jinyuannangua”were better in quality and yield,and thus were suitable for planting in Hunan Province.
