摘要
为使杂交玉米新品种顺单6号得到大面积推广应用,利用区域试验资料,采用联合方差分析法、均值-变异数法、适应度法、产量与环境指数的回归系数及相关系数对顺单6号的丰产稳产性进行分析,结果表明:顺单6号属高产、稳产、耐密型玉米杂交种,适宜于贵州中西部生态区推广种植。
The testing results of Shundan 6,a new hybrid maize variety,in regional tests were analyzed by using the joint variance analysis,mean-variance method,the fitness method,regression coefficient and correlation coefficient of yield and environmental index to determine its high and stable yield ability for its further large-scale popularization.The results showed that Shundan 6 with high and stable yield and density tolerance could be popularized in the midwest ecotope of Guizhou province.
