Summary:The invention discloses a breeding method of a large-panicle indica-japonica intermediate type wide-compatibility restorer line, which comprises the following steps: hybridizing a dense-panicle or dense-panicle rice germplasm resource as a parent with a long-panicle indica-japonica intermediate type wide-compatibility restorer line to obtain a hybrid F1 seed, planting the F1 and selfing to obtain an F2 seed, and breeding the F2 seed to obtain the large-panicle indica-japonica intermediate type wide-compatibility restorer line. Selecting a large-ear multi-grain single plant with excellent plant leaf morphology from the separated F2 group to harvest seeds, performing continuous multi-generation selfing, investigating the ear grain type structure of each generation, and selecting the plant leaf morphology to obtain the large-ear multi-grain indica-japonica intermediate type wide-compatibility restorer line with excellent plant leaf morphology. Compared with the prior art, the large-panicle indica japonica interm
