浙江省粽子专用糯稻品种筛选及其综合评价

为筛选适宜浙江地区种植的粽子专用优质糯稻品种材料，以环太湖地区收集的27份糯稻种质为研究对象，采用相关分析、主成分分析法和聚类分析法对其田间产量、米质和加工成粽子的食味品质等指标进行综合评价。结果表明：粽子的受喜爱程度与粽子的气味、软硬适宜度、蛋白质含量呈显著正相关；根据主成分分析结果，绍糯9714的综合得分最高；根据5个主成分得分进行聚类，可将27份糯稻种质资源划分为5类，其中适合做粽子的糯米主要集中在第1类(浙糯优1号、浙糯106、绍糯9714、嘉禾糯1号，具有较好的品相、感官和加工品质，综合评分高)、第2类(皖垦糯1116、太湖糯、澄糯218、镇糯19、苏御糯、糯示02、糯示03、糯示05、香糯833,该类群具有较好的风味品质，但产量和品质较差，综合评分中等)和第3类(皖垦糯1号、糯示01、糯示04、糯示06、糯示07、糯示08、皖垦糯3号、武育糯4819,该类群具有较好的感官品质，综合评分中等),结合直链淀粉含量低于2%、粽子紧实度大于0.9的生产要求，最终筛选出适合浙江省种植的粽子专用糯稻品种材料有绍糯9714、浙糯106、糯示01、皖垦糯3号、浙糯优1号、嘉禾糯1号。

Selection and comprehensive evaluation of special glutinous rice varieties for dumpling in Zhejiang Province,China

To select high-quality glutinous rice varieties suitable for making dumpling (glutinous rice dumpling wrapped in reed leaf) in Zhejiang Province, 27 glutinous rice germplasm resources were collected around Taihu Lake as materials. The field yield, rice quality and eating quality of dumpling were evaluated by correlation analysis, principal component analysis and cluster analysis from glutinous rice varieties. The results showed that there was a significant positive correlation between the favorite degree of dumpling and smell, suitability of soft and hard, and content of protein. Principal component analysis indicated that comprehensive evaluation value of Shaonuo9714 was the highest. 27 glutinous rice resources were divided into 5 classes by cluster analysis. It was suitable for making dumpling to concentrate in glutinous rice class 1 (Zhenuoyou No.1, Zhenuo 106, Shaonuo 9714, Jiahenuo No.1, with good appearance, sensory and processing quality and high comprehensive score), class 2 (Wankennuo 1116, Taihunuo, Chengnuo 218, Zhennuo 19, Suyunuo, Nuoshi 02, Nuoshi 03, Nuoshi 05 and Xiangnuo 833, which had good flavor quality, but poor yield and quality, with medium comprehensive score) and Class 3 (Wankennuo 1, Nuoshi 01, Nuoshi 04, Nuoshi 06, Nuoshi 07, Nuoshi 08, Wankennuo 3 and Wuyunuo 4819, which had good sensory quality and medium comprehensive score). Combined with the production requirements that the amylose content was less than 2% and the compactness of dumpling was greater than 0.9, the special glutinous rice varieties suitable for dumpling planting in Zhejiang were Shaonuo 9714, Zhenuo 106, Nuoshi 01, Wankennuo 3, Zhenuoyou No.1 and Jiahenuo No.1.
