Production of Pelargonium lines comprising a great variety on the characteristics, including flower color.

天麻属植物体型庞大，有近缘种230种，划分为11-16组。本研究的目的是：1)通过荧光显微镜观察天花粉管在花柱中的行为，推测天麻属野生种之间的亲缘关系；2)在此基础上，高效地选育出花色等性状多样性较大的种间和组间杂交系。材料为野生种，分属于9个组，即天南星属、天南星属、多花属、连翘属、金鱼藤属、山茶属、大蒜属、鸡冠花属、没药属。野生种间的交叉亲和力是杂交组合所特有的。根据植株习性、花器官、叶片、精油等形态性状(植株习性、花器官、叶片、精油等)，通过杂交和胚珠培养技术获得杂种F_1代植株。证券交易委员会之间的物种间杂交。霍里亚和美国证券交易委员会。天竺葵比父本更容易，后者作为母本比父本更成功。本研究获得的花色等性状变异较大的品系可作为天葵育种材料。

The genus Pelargonium is large, with about 230 species arranged into groups of related species and classified 11-16 sections.The present study was carried out 1) to presume cross affinity relationship among wild species of genus Pelargonium according to elucidate the behavior of pollen tubes in the style by means of the fluorescence microscope, on the base of these result, 2)to produce efficiently the inter-species and-sectional hybrids lines comprising a great variety on the characteristics, including flower color. The materials are wild species belong to 9 sections, i.e., Hoarea, Pelargonium, Polyactium, Ligularia, Jenkinsonia, Campylia, Glaucophyllum, Cortsusina, Myrrhidium. The cross affinity among wild species is peculiar to the cross combination. All of them producing F_1 plants by crossing and by means of ovule culture technique estimated to hybrids on the base of the morphological characteristics(plant habits, flower organ, leaf, essential oil ).F_1 plants obtained from interspecies hybridization in the section Hoare showed a great variety on the flower color, producing by the variety of the value of L^* a^* b^*. Interspecies hybridization between the sec. Hoarea and the sec. Pelargonium was easier and the later was more successful as a female parent than as a male parent. Lines comprising a great variety on the characteristics, including flower color, producing in this study are very useful for breeding materials in Pelargonium
