目前,玉米鉴定试验的评价主要是以产量结果作为依据,而对与产量相关的农艺性状,常采用直观分析或平均数统计,分析结果相互独立。筛选出一些产量高而品质、抗病、抗倒性等其他性状较差的组合,而淘汰了稳产性好 At present, the evaluation of maize identification test is mainly based on the yield results, while the agronomic traits associated with the yield often use visual analysis or average statistics, the analysis results are independent of each other. Some high yield and quality, disease resistance, lodging resistance and other combinations of poor traits were screened out, and the good yield stability was eliminated
