| 摘 要： | 试验研究和育种实践表明,在保证一定穗数的基础上争取粒多、粒重,是大幅度提高小麦产量的有效措施;提高穗重是选育穗重型高产良种的主攻目标。经遗传分析结果,千粒重遗传力相对较高,早代选择有一定效果。粒大饱满是良种的优良性状,也是适应环境条件的重要表现。

| Abstract: | Experiments and breeding practice showed that to obtain more and heavier grains of each ear based on certain quantity of cars is the effective measures for getting higher yield of wheat and to increase the ear-weight is the main goal of selecting high-quality wheat varietes. The result of inheritancy analysis demonstrated that the inheritancy force of the weigh per 1000 grains is high, so the early selection in generation is some effects. |

| Keywords: | Wheat ear-weight type inheritancy force. |
