This obviously can not meet the current needs of agricultural development. Guided by the great strategic principle of “preparing for war, preparing for war and for the people,” Chairman Mao has, under the guidance of Chairman Mao’s glorious philosophical thinking, worked out a set of relatively rapid rice hybrids in practice in recent years
