摘　　要：根据长江下游地区的自然条件和小麦品种产量水平的发展趋势 ,提出了小麦超高产育种的目标 ,指出小麦超高产育种的突破口应是在保证一定穗数的基础上 ,着重增加每穗粒数和千粒重来主攻穗重。对如何选育超高产优质品种的途径和方法作了针对性探讨。According to the natural conditions and the trends of wheat production in the lower reaches of the Yangtze River, the objectives of super high yield of wheat are put forward. The key to the super high yield breeding of wheat should increase the number of grains per spike and 1000 grain weight on the basis of the optimum number of ears per unit area. The approaches on how to develop the wheat varieties with super high yielding potential and high quality are also discussed in the paper.
