The aim of this proposal is to determine whether different levels of genetic relatedness between pollen donor and recipient affect pre- and postfertilization stages during reproduction in individuals from a population of radish, Raphanus sativus. The project is organized into three objectives: (1) The effect of inbreeding on fruit and seed development and the growth and reproduction of inbred progeny will be analyzed for five different levels of genetic relatedness shared between pollen donor and recipient. (2) Pollen/style interaction will also be examined as a function of five levels of inbreeding. (3) Inbreeding effects will be examined statistically to analyze patterns of genetic structure within several natural populations. This research will be the first to investigate in detail the effects of inbreeding in a self-incompatible plant population and thus will provide valuable data relative to the analysis of realized mating patterns and the general study of microevolution in self-incompatible plants.

本提案的目的是确定是否存在不同的 花粉供体和受体之间的遗传相关水平 影响生殖过程中的受精前和受精后阶段， 个体从萝卜，萝卜的人口。 的 项目分为三个目标：（1）效果 近亲繁殖对果实和种子发育以及生长和 将分析近交后代的繁殖， 花粉之间存在着不同程度的遗传关联 捐赠者和接受者 (2)花粉/风格的相互作用也将是 根据五个级别的近亲繁殖进行了检验。 （三） 近亲繁殖的影响将进行统计学检查， 几个自然种群的遗传结构模式。 这项研究将是第一个详细调查 自交不亲和植物群体中近交的影响， 因此，将提供有价值的数据， 实现交配模式和微观进化的一般研究 自交不亲和的植物。
