玉米育种组合产量试验的问题探讨

Studies on the Problems of Maize Breeding in Yield Traits

对玉米组合的鉴定试验、品比试验和区域试验结果进行了初步分析。结果表明:鉴定试验与品比试验的结果差异悬殊,这可能是由于两种试验设计上的不同所致,鉴定试验为单行区,而品比试验为多行区,取中间行测产。提出玉米育种组合产量试验中可能存在的一些问题,以便进一步讨论。

The research on consistent oi identical trail, variety comparative tnal and regional triat was conducted in the study. The difference between results of identical trial and variety comparative trial were large. It was maybe related to the differences of design between the two trials. In the identical trial, the plot only had a single row of plants, and in the variety trail, the plot had multiple rows of plants. The aim of this article was to discover the problems existing in the yield trials for maize breeding.
