摘　　要：对与小麦产量相关的几个性状进行了探讨。认为选育灌浆初期株型较为紧凑、叶片直立,随灌浆进行叶片夹角逐渐增大,灌浆后期株型较为松散、叶片趋向水平,株型叶型具有动态变化的品种,易获得高产稳产;现代品种改良需要在一定收获指数的基础上,注重生物产量和收获指数的协同提高;单茎粒数叶比和单茎粒重叶比、单位面积粒数与群体产量有着很好的正相关;孕穗早期到开花期长短和绿叶面积持续期是决定产量的关键时期。A few of characters related to wheat field were discussed in the paper.h was considered that breeding vari- eties of plant-type compact in grain filling at early stage, with upright ｜eaves, leaf angle become larger along with grain filling, then plant-type loose, leaf tend to level, plant-type and leaf-type with dynamic changes could get high and stable yield ; improvement of crop cultivars should be based on certain harvest index, pay attention to improve bi- ological yield and harvest index together; there was a good positive correlation between grain number per spike/flag leaf area （GNPS/FLA） and spike grain weight/flag leaf area （SGW/FLA） of single stem and grain numbers per unit and population yield ; the period between booting early stage and blooming period and green leaf area duration was critical to high yield.
