摘　　要：通过田间产比试验,探讨了不同粒位玉米种子的产量潜力。结果表明,不同粒位的种子在种子大小、粒重及幼苗长势等方面存在一定差别,但对玉米中后期生长及最终产量没有明显影响。表明不同粒位的玉米种子具有相同的产量潜力。The yield productivity of maize seeds at different grain location were studied by the yield experiment. The results showed that there are some differences in seed size, seed weight and seedling bloom on the maize seeds, but in the final yield and middle late growth. So as the productivity is identical.
