【Abstract】 By construction of the models R150,T89,T242 and 9829,it is identified that RDB(rice directional breeding) has some characterizations of direction and short cycle from breeding technology strategy,route,character operation and selection.In addition,some famous successful breeding theories and practices of genetics and breeding modles have been discussed.更多还原
