Development of DUS testing guidelines for new Atractylodes lancea varieties
摘要
Abstract
Atractylodes lancea is a perennial herbaceous plant of Asteraceae,with rhizomes for medical use.However,A.lancea plants from different habitats have great variability,and the germplasm resources of A.lancea are unclear and mixed during production.Therefore,it is urgent to protect new varieties of A.lancea.The distinctness,uniformity,and stability(DUS)testing of new plant varieties is the foundation of plant variety protection,and the DUS testing guidelines are the technical basis for variety approval agencies to conduct DUS testing.In this study,the phenotypic traits of 94 germplasm accessions of A.lancea were investigated considering the breeding and variety characteristics of A.lancea in China.The traits were classified and described,and 24 traits were preliminarily determined,including 20 basic traits that must be tested and four traits selected to be tested.The 20 basic traits included 3 quality traits,5 false quality traits,and 12 quantitative traits,corresponding to 1 plant traits,2 stem traits,8 leaf traits,6 flower traits,and 3 seed traits.The measurement ranges and coefficients of variation of eight quantitative traits were determined,on the basis of which the grading criteria and codes of the traits were determined and assigned.The guidelines has guiding significance for the trait evaluation,utilization,and breeding of new varieties of A.lancea.关键词
