| 摘 要： | 用灰色系统理论中的关联度分析法对甜菜种质资源的优良种质进行多性状综合评判，结果１０１２Ｂ和７８００１６Ａ／２的等权与加权关联度均居第一位和第二位，说明１０１２Ｂ的综合性状表现最好，７８００１６Ａ／２稍次，两者为是优种质；７４１２／８２＿３、７４１２／８２＿（３－４）和１０１２Ａ的等权关联度依次靠后，与其加权关联度位次相差不大，说明３份材料的综合性状表现较好；其它两份材料（Ｇ７９６８０、１３０１／９）分属高糖型、丰产型种质。

| Abstract: | Manv charactcre of fine sugar bcet gcrmplasm resource have judged comprehensively by the association degree method in the theory of grisent system,1012B and 780016A/2 gave the lst and 2nd place with the equal and weighting,1012B is the best one for comprehensive characters,and 2nd one is 780016A/2,these two are the best germplasm.7412/82_3,7412/82_(3-4) and 1012A have the better comprehensive characters and their asso ciation degree with equal and weighting were the same,the other G79680,1301/9 belong to high sugar,high yieldgernplasm. |
