菠菜是一种杂种优势很强的蔬菜之一。在国外特别是日、美、欧洲等国应用杂种一代极为广泛。我国已在逐渐选育推广杂种一代菠菜。目前,我国大多采用品种间、自交系间杂交生产杂种一代。育种实践证明:外观长势好、产量高的亲本杂种产量不一定高,只有配合力高的亲本才能配出高产的杂种。 Spinach is one of the vegetables with strong heterosis. In foreign countries, especially Japan, the United States, Europe and other countries a very wide range of hybrids. China has been gradually breeding hybrid generation of spinach. At present, most of our country adopt the hybrid generation between varieties and inbred lines.
