新疆大蒜品种农艺、产量及品质关系综合评价研究

Research on Comprehensive Evaluation for the Relationship AmongAgronomy,Yield and Quality of Xinjiang Garlic

以大蒜为试材,采用灰色关联度法和DTOPSIS法研究了大蒜产量、农艺性状、品质性状三者间的关系(密切程度),并对参试的6个大蒜品种进行了综合性评价。结果表明,与产量关系密切的农艺性状是大蒜株高、收获株数、外层瓣数、抽薹率、生育期和单球重,与产量关系密切的品质性状是大蒜素、蒜氨素和维生素C,这些性状应作为今后大蒜种质资源综合评价的重点研究对象;品种xjgar 1、xjgar 3和xjgar 4在两地的试验结果综合评价较高,可作为大蒜种质资源与创新繁育的基础资源进行深入研究。

Using garlic as the test material,the gray correlation method and DTOPSIS method were used to study the relationship(Closeness)among garlic yield,agronomic traits,and quality traits,and a comprehensive evaluation was made on the six garlic varieties.The results showed that the agronomic traits closely related to yield were garlic plant height,harvested plant number,outer petal number,bolting rate,growth period and single ball weight,and the quality traits closely related to yield were allicin,alliin and vitamin C,which should be the key research objects for comprehensive evaluation of garlic germplasm resources in the future.The comprehensive evaluation of the varieties xjgar 1,xjgar 3 and xjgar 4 in the two palces was relatively high,which could be used as garlic germplasm resources and basic resources for innovative breeding for in-depth research.
