    摘要:

    采用杂交、回交与定向自交系统选育方法,借助高效液相色谱检测技术,创新育成一批富肌醇南瓜新种质,并利用杂种优势技术,育成富肌醇南瓜新品种一串红。经检测,一串红的肌醇含量达661mg/100g,比普通南瓜品种高出120%以上;多糖含量达45.8mg/g,比普通南瓜品种高出30%以上;葡萄糖含量小于50mg/g,且鲜食品质好,兼具丰产、抗病等优良性状,春秋两季均可栽培,适合糖尿病、高血压、高血脂等人群作为日常食疗保健食品。

    Abstract:

    Aggregation breeding method was used to create the new pumpkin germplasm with high inosital that was analyzed with the HPLC technique. A new pumpkin cultivar ‘Yichuanhong’ was obtained. The contents of inositol and polysaccharide in the fruits of ‘Yichuanhong’ were 661mg/100g and 45.8mg/g, which were 120% and 30% higher than CK cultivars, respectively. The results also showed that this new cultivar had low reductive sugar, less than 50 mg/g. Therefore, it is suitable to be used in the daily diet treatment by the people with diabetic, hypertention, or heart disease. Besides, ‘Yichuanhong’ has good eating quality, high yield, and diseases resistance. This cultivar can be cultivated in both spring and autumn. ‘Yichuanhong’ has greatly increased the economic value of pumpkin as a traditional vegetable, and provided a safe and effective means to prevent diabetic, hypertention, or heart diseases.
