14份蒌蒿种质资源主要农艺性状及营养成分评价

Major Agronomic Traits and Nutrient Contents Evaluation of 14 Accessions of Seleng Wormwood(Artemisia selengensis Turcz.)Germplasm Resources

为了综合评价蒌蒿(Artemisia selengensisTurcz.)种质资源的育种价值,对14份蒌蒿种质材料的主要农艺性状和营养成分进行了鉴定。结果表明,14份资源中包括蒌蒿原变种(A.selengensisvar.selengensis)和无齿蒌蒿(A.selengensisvar.shansiensis)两个变种。株高31.04~53.38cm,地上茎节间长2.70~4.16cm、直径0.51~0.61cm,单株分蘖数6.47~14.01个,地上茎产量3.01~6.35kg·m^(-2)、根状茎产量0.26~1.08kg·m^(-2);地上茎干物质含量7.40%~9.60%,蛋白质含量1.83%~2.33%,总糖含量0.46%~0.86%,粗纤维含量0.30%~0.52%。以选育地上茎高产品种为目的时,波阳红梗蒌蒿-3、鄱阳湖野蒿-4是比较适宜的育种材料;以选育根状茎高产品种为目的时,小叶白、小叶青及大叶青为适宜的育种材料。都江堰蒌蒿具有独特的芳香气味,是选育芳香气味浓郁品种的良好材料。

In order to evaluate the potential breeding value of seleng wormwood（Artemisia selengensisTurcz.）germplasm resources,this paper carried out identification on the main agronomic traits and nutritioncontents of 14 accessions of seleng wormwood germplasm resources.The results showed that among these 14accessions,2 mutations A. selengensis var. selengensis and A. selengensis var. shansiensis were included.Theplant height was 31.04-53.38 cm. The internodes of aerial stems were 2.70-4.16 cm in length and 0.51-0.61 cm indiameter.The tiller numbers of single plant were 6.47-14.01.The yield for aerial stems were 3.01-6.35 kg·m-2 ,and 0.26-1.08 kg·m-2 for rhizomes.The contents of dry matter,protein,total sugar and crude fiber of aerialstems were 7.40%-9.60%,1.83%-2.33%,0.46%-0.86% and 0.30%-0.52%,respectively.The accessions‘Boyanghonggenglouhao-3’ and‘ Poyanghuyehao-4’ were appropriate materials for high aerial stem yieldbreeding,and‘ Xiaoyebai’,‘Xiaoyeqing’ and‘ Dayeqing’ were better materials for high rhizome yieldbreeding.In addition,the accession‘ Dujiangyanlouhao’ is good for strong aroma breeding because of its specialaromatic ordour.
