Chemosystematic of Tulips based on tepal anthocyanins as phenetic markers

本研究主要针对郁金香品种和品种(系)的建立，以花被片花色苷为遗传标记，根据花被片花色苷的色素分布信息和后代的相互参照，以花被片花色苷为遗传标记，阐明郁金香属种和品种(系)的建立。根据Ward‘s最小方差聚类分析，将414个品系分为A、B两大类，A大类包括310个大类，Pg和Cy大类，B大类包括104个大类。建议将郁金香品种与DP优势种进行分化，从而建立现有的更新或进一步分化的表型系。

The research is focused on the clarification of the establishment of Tulip species and cultivars (lines) by chemosytematics based on tepal anthocyanins as phenetic markers in accordance with the information on the pigments-distribution as well as the progenies' cross references based on the inheritance of tepal anthocyanidins. The seven major anthocyanins are identified and base on the 13 pigment patterns, 414 lines are divided into the 2 large clusters A and B according to Ward's minimum variance cluster analysis; the cluster A included 310 lines based on the major anthocyanidins, Pg and Cy, and the cluster B included 104 lines due to the major anthocyanidin, Dp. The Tulip cultivars are suggested to differentiate from the Dp-dominant species thus concluded to establish the updated or further differentiated phenotypic lines as existed in nowadays.
