摘要:

调查了234份葡萄种质资源的果穗穗形,将果穗基本形状细分为长圆锥形、短圆锥形、长圆柱形、短圆柱形和分枝形5种。其中长圆锥形的品种最多,占34.61%;其次是短圆锥形的品种,占33.33%;分枝形的品种最少,占5.13%。鲜食品种中果穗形状以长圆锥形为主,酿酒品种以短圆锥形为主。采用概率分级的方法对葡萄果穗长度、宽度、质量和大小进行重新分级,以这4个性状为参考运用模糊综合评判法对不同品种葡萄果穗进行评价。结果显示,加权评价与等权评价结果基本一致,并得到‘天秀’(V. vinifera × V. labrusca‘Tensyū’)、‘绯红’(V. vinifera‘Cardinal’)、‘凯旋’(V. vinifera × V. labrusca‘Triumph’)等果穗形状综合评分高的品种。这一研究丰富了葡萄品种资源评价内容,同时也为葡萄种质资源的进一步利用和品种选育提供了理论依据。

Abstract:

The present study investigated the cluster shape of 234 varieties of grape germplasm resources. According to the“Descriptors and Data Standard for Grape(Vitis L.)”,we further categorized the grape cluster shape into the following five classes:long cone,short cone,long cylinder,short cylinder and branch. Among them,varieties with the long-cone clusters are dominant(34.61%),followed by the short-cone(33.33%),and the branched varieties are the least(5.13%). The cluster shape of table grape is mainly long conical,while the shape of wine grape is mainly short conical. The probability grading method was adopted to determine the hierarchical criterion of cluster length,width,weight and size. Using the above four traits as parameters,the fuzzy synthetic evaluation method evaluated the cluster appearance of the grape germplasm resources by giving each cultivar a specific score. The results of weighted evaluation and equal weight evaluation were generally consistent,and some varieties with good appearance,such as ‘Tensyū’,‘Cardinal’and‘Triumph’,were obtained. This study not only enriches the grape germplasm resource evaluation,but also provides a theoretical basis for further utilization of grape germplasm resources to breed new varieties.
