贵州是国内玉米地方品种较丰富的地区之一，经过长期的进化演化和人工选择，形成了丰富的种质资源，广泛分布于全省各地不同的自然生态区域。实践证明地方种质对当地生产条件良好的适应性。加强地方种质研究与充分利用外来种质相结合，因地制宜地选育多种类型的杂交种并合理配
Guizhou is one of the richest maize landraces in China. After long-term evolutionary evolution and artificial selection, Guizhou has formed a wealth of germplasm resources and is widely distributed in different natural ecological regions across the province. Practice has proved that local germplasm good adaptability to local production conditions. Strengthen local germplasm research and make full use of foreign germplasm, in accordance with local conditions to breed more types of hybrids and rational allocation
