Yulin actively and steadily, according to local conditions to develop hybrid rice, to adjust the layout of agriculture and grain production has made a greater contribution. It is of great significance for us to seriously summarize the experience of breeding and breeding that we have explored over the past few years and make breakthroughs in gaining a breakthrough in the production of late seeds this year. First, high-yielding seed production techniques 1. Choose a good combination. A good combination should have the following five: ① superiority, ② resistance, ③ high quality rice, ④ easy seed, ⑤ adapt to local conditions. Years of real
