| 摘 要： | 为了提高小麦产量,以多穗型、中穗型和大穗型小麦为材料,通过不同密度对产量结构的调查、分析和探讨及其有关性状的研究,找出小麦生产中存在的主要问题,证明小麦产量构成因素中,决定产量的主导因子是穗数,其次是千粒重,最后是穗粒数。并提出今后小麦高产育种策略应增加有效分蘖,稳定千粒重,挖掘穗粒数的潜力;并对今后黄淮北片麦区小麦高产育种途径进行了探讨。

| Abstract: | To improve wheat yield, ear types of the multi, medium and the big were applied as material, effect of ear density type to yield composition and the related characters were studied to identify main existing problems in wheat production. The results showed that in yield composition, ear number was the major important element, and 100 - seed - weight and seed number per ear were important elements followed. It suggested that in high yield breeding, it is important to increase productive tiller, to stable 100 - seed - weight and to tap the latent potentiality of seed number per ear. In addition, channel is approached for wheat high yield breeding for north part of Yellow River and Huaihe River region. |
