通过连续两年试验，发现应用单基因ｂｒ－ ２ 矮生系与多基因矮生系组配，其Ｆ１ 植株高度可进一步矮化，株叶结构颇近似于较为理想的矮秆型杂交种，为单基因ｂｒ－ ２ 矮生系的应用和培育优良矮秆型杂交种提供了依据，开辟了新的途径。
After two consecutive years of experiment, it was found that F1 plant height can be further dwarfed by applying single-gene br-2 dwarfism and multi-gene dwarfism. The structure of plant leaf is similar to the ideal dwarf hybrid, The application of single-gene br-2 dwarf lines and breeding of excellent dwarf hybrids provide the basis for opening up new avenues.
