蒲公英（Taraxacum koksaghyz Rodin，TKS）已被研究作为橡胶生产的替代来源，但也代表了生产菊粉的潜在来源。2008年，Kirschner在哈萨克斯坦的一次探险中收集了TICS种子，以分析所选野生TICS种群的农艺学特征。分别对9个群体和2个种植期进行了检测。测定根干重、橡胶和菊糖含量，并进行统计学评价。单株间所有性状变异较大。尽管如此，橡胶和菊粉含量的一个显着的群体效应进行了检测。菊糖含量和根干重不存在播期效应，但存在显著的群体-播期互作效应。虽然产量相对较低，但在特定种植日的群体20、30和38是增加橡胶和/或菊粉产量的有希望的候选者。在任何情况下，都需要进行额外的农艺学研究，特别是使用大量选择和杂交进行密集育种，以将TICS转化为用于橡胶和菊粉生产的有用作物。(c)2016爱思唯尔B.

Taraxacum koksaghyz Rodin (TKS) has been studied as an alternative source for rubber production, but represents also a potential source for producing inulin. TICS seeds were collected in 2008 in an expedition to Kazakhstan by Kirschner in order to analyze agronomical characteristics of selected, wild TICS populations. Nine populations and two planting dates, respectively, were examined. Root dry weight, rubber and inulin content were measured and evaluated statistically. Large variations for all traits were observed between single plants. Despite of this, a significant population effect for rubber and inulin contents was detected. No planting date effect was observed, but a significant interaction effect of population by planting date for Inulin contents and root dry weight. Although yields are relatively low, populations 20, 30 and 38 at specific planting days are promising candidates for increased rubber and/or inulin production. In any case additional agronomic studies are required and pafticularly intensive breeding using mass selection and crossings, for converting TICS into a useful crop for rubber and inulin production.
