摘　　要：通过两个高油玉米品种与5个普通玉米品种混种,利用高油玉米品种为普通玉米品种授粉,研究高油玉米对普通玉米的花粉直感效应。两年的研究结果表明:通过花粉直感效应,增加了普通玉米的含油量和粗蛋白含量,改变了淀粉含量。与通油1号玉米杂交的5个普通玉米产量均增加,增加幅度最高的是吉单180,其经济效益也最大。与四油199玉米杂交的5个普通玉米,除吉单180外,产量均降低,经济效益最高的是吉单180。由此可见,高油玉米通油1号比四油199更适合与普通玉米进行花粉直感效应,而吉单180是与高油玉米进行花粉直感效应最为合适的普通玉米品种。Through the interbreeding between the high-oil maize and the five normal maize varieties, we made some research on the pollination effect of normal maize by high-oil maize. On the basis of the two years experiments, we drew the conclusion that high-oil maize had a obvious pollination effect to normal maize which increased the crude fat and protein content, changed the starch content. Pollinated by Tongyou No. 1, the yield of the five normal maize varieties was all increased, and Jidan180 had the biggest yield and the largest benefit. Pollinated by Siyou199, except Jidan 180, the yield of the other four maize varieties was all decreased, and Jidan 180 had the largest benefit. From the above, we can tell that high oil maize of Tongyou No. 1 is a better variety that interbreeds with normal maize variety than Siyou199, Jidan180 is the optimum normal maize variety that interbreeds with the high oil maize.
