玉米育种是为了了解生产需求并创造性的满足生产需求的一个过程,其通过特定的种植模式以及栽培密度针对玉米品种进行试验。基于此,所选取的材料是2000-2013年某省趋于试验杂交组合,研究不同时期杂交组合的生育期的变化以及穗行数的变异情况。以探寻单位面积增强玉米产量的目的。
Corn breeding is a process to understand production needs and creatively meet production needs by testing corn varieties with specific planting patterns and planting densities. Based on this, the selected materials are from 2000 to 2013 in a province to test the hybrid combinations to study the growth of hybrid combinations at different stages of growth and variation of the number of rows. To explore the unit area to enhance corn production purposes.
