项目摘要

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

天竺葵属（Pelargonium）是一个庞大的属，约有230种，分布在亲缘种群中，分为11-16个节。本研究的目的是：1)利用荧光显微镜对天竺葵花柱内花粉管的行为进行分析，推测天竺葵属野生种间的亲和关系，并在此基础上，高效地选育具有多种特征（包括花色）的种间、节间杂交种。材料为野生种，分9个科，即Hoarea、Pelargonium、Polyactium、Ligularia、Jenkinsonia、Campylia、Glaucophyllum、Cortsusina、Myrrhidium。野生种间的杂交亲和是杂交组合所特有的。通过杂交和胚珠培养技术，根据形态特征（植株习性、花器官、叶片、挥发油）鉴定为杂种。Hoare区种间杂交获得的F_1植株在花色上表现出很大的变化，由L^* a^* b^*的变化值产生。霍利亚和天竺葵的种间杂交比较容易，后者作为母本比作为父本更成功。本研究产生的品系在花色等性状上具有很大的多样性，可作为天竺葵的选育材料
