本文介绍了贵州省玉米育种和生产的现状 ,并对贵州当前主要应用的 35份玉米杂交种进行分析 ,发现模式组合“地方种质×外引种质”在杂交种模式中占主导地位 ,占 6 8%。这说明贵州复杂的生态环境需要地方种质的适应性、抗逆性 ,也需要外引种子来增大遗传差异 ,而获得更大的杂种优势。同时发现 ,自 330类系及 785 99、Reid、旅大红骨子等类群中的个别系 ,温光反应较迟钝 ,能在贵州表现较好的适应性 This paper introduced the status quo of maize breeding and production in Guizhou Province and analyzed 35 main maize hybrids currently used in Guizhou Province. It was found that the pattern combination “local germplasm × foreign germplasm” dominates in hybrid model, accounting for 6 8%. This shows that the complicated ecological environment in Guizhou needs the adaptability and resistance of local germplasm, and also requires the introduction of seeds to increase the genetic difference and achieve greater heterosis. At the same time, it has been found that the warm and light responses are relatively slow in 330 lines, 78599, Reid and Ludao red bones, which can show good adaptability in Guizhou
