Abstract

It is valuable to set an ideotype plant structure (i.e., ideal numbers and arrangement of sucrose sources, sinks, and pathways that maximize crop yield) as a goal for breeding with modern and near-future technologies. However, it is not easy to theoretically specify an ideotype because multiple factors need to be considered simultaneously. Here a method to obtain plant ideotypes using a simple mathematical model is described. The model identifies plant structures with maximal yield through a series of simulations of the dynamic changes in sucrose concentration at different positions of the plant. Originally developed for rice, this revised method can be applied to a wide range of crop plants.

摘要

将理想型植株结构（即蔗糖源、库及途径的理想数量和排列方式，以实现作物产量最大化）设定为利用现代及近期技术进行育种的目标是很有价值的。然而，从理论上明确理想型并不容易，因为需要同时考虑多个因素。本文描述了一种使用简单数学模型获取植株理想型的方法。该模型通过对植株不同位置蔗糖浓度动态变化的一系列模拟，识别出产量最大化的植株结构。这种改进后的方法最初是为水稻开发的，可应用于多种作物。
