摘　　要：Plant architecture can act as a pivotal determinant of crop yield by maximizing photosynthate accumulation in grains,but no B.napus rapeseed ideotype has yet been defined.However,semi-dwarf and compact(SDC)rapeseed plant types with the capacity to maximize silique number per hectare and seed weight per silique are expected to optimize plant architecture for groundbreaking seed yield,avoiding lodging and promoting mechanical harvest(Liu et al.,2022).In this study,we report the mutant dc1,which exhibits DC plant architecture with significantly increased silique number in the main inflorescence compared with currently cultivated high and loose(HL)plant types like those of elite cultivars(Figure 1A and Supplemental Figure 1).
