用开花期不同的3个大豆品种和结荚习性不同的2个品种进行的研究表明:品种开花期越早,大豆花叶病毒的种传株率和种传苗率越低,开花期越晚,种传株率和种传苗率越高;有限结荚品种种传期较短,无限结荚品种种传期较长。 The results showed that the earlier the flowering period was, the lower the rate of plant-borne and seedling transmission and the later flowering stage of soybean mosaic virus were studied by using three different soybean cultivars with different flowering periods and two varieties with different pod habits. , The rate of plant-borne plants and the seedling-planting rate are higher; the limited varieties of pod varieties have shorter rag-dates, and the unlimited varieties of pod products have longer races.
