近几年来北京秋茄子单产低而不稳,全市平均亩产仅2000来斤。除了没有进行科学管理外,最根本的是由于缺乏适应北京地区秋季环境条件(包括病虫害)的品种。因此,很有必要研究和选育适于北京地区栽培的秋茄子品种。为此,首先就要了解京郊目前使用的主要秋茄子品种的产量潜力。因为产量是一个品种的综合特征,通过对它的研究可以比较全面地认识一个品种的一般的育种价值。本试验拟从配合力的研究入手,来研究茄子的育种价值。这是
In recent years, Beijing autumn eggplant yield low and unstable, the city average yield of only 2000 pounds. Apart from the lack of scientific management, the most fundamental reason is the lack of varieties that adapt to the autumn environmental conditions in Beijing, including pests and diseases. Therefore, it is necessary to study and select suitable autumn cultivated varieties of autumn eggplant in Beijing. To do this, we must first understand the potential yield of the main autumn eggplant varieties currently used in the suburb. Because yield is a comprehensive feature of a variety, through its research can more fully understand the general breeding value of a variety. This experiment intends to start with the study of combining ability to study the breeding value of eggplant. this is
