SELF-FERTILIZATION AND QUANTITATIVE TRAIT EVOLUTION

这项研究将调查自交受精对 通过自然选择或人工选择进行的植物种群进化。 目标是(L)开发一个数学模型来预测反应 在部分自交群体中作为遗传函数的选择 参数；(2)对该模型进行分析，以确定在什么遗传条件下 假设自我受精预计会加速或延缓 选择；以及(3)用一个新的模型检验该模型的经验充分性 植物种类含羞草的人工选择试验 古特塔斯。这一模型的发展将有助于野外生物学家 对自然选择的调查，还应促进 开发有效的技术来选择性地改进 农业植物。高效的植物育种计划对 维护和提高人类健康和营养标准。

This study will investigate the consequences of self-fertilization for the evolution of plant populations by either natural or artificial selection. The objectives are to (l) develop a mathematical model to predict response to selection in a partially selfing population as a function of genetic parameters; (2) analyze this model to determine under what genetic assumptions self-fertilization is expected to accelerate or retard selection; and (3) test the empirical adequacy of this model with a novel type of artificial selection experiment on the plant species Mimulus guttatus. The development of this model will aid field biologists in investigations of natural selection and should also facilitate the development of efficient techniques for the selective improvement of agricultural plants. Efficient plant breeding programs are critical to the maintenance and improvement of human health and nutrition standards.
