在群体条件下，对旱地杂种小麦的主要农艺性状及其与产量的关系进行了分析。结果表明：旱地杂种小麦的株高、分蘖成穗率、穗数、穗粒数、生物产量和经济产量具有明显超标优势。强优势组合的穗粒数、穗粒重优势突出。穗数、穗粒数、生物产量与经济产量呈显著或极显著相关。穗粒数、穗粒重对产量的直接作用较大。筛选强优势组合时，应重点对穗粒数和穗粒重进行正向选择。 Under the group condition, the main agronomic traits of dryland hybrid wheat and its relationship with yield were analyzed. The results showed that the dry weight of wheat, plant height, tillering rate, spikes, grains per spike, biomass yield and economic yield had obvious superiority. Strong combination of grain yield per spike, grain weight prominent. The number of spikes, grains per spike, biomass yield and economic yield were significantly or extremely significantly correlated. The number of grains per ear and the weight of ear grains had a direct effect on the yield. When selecting the strong combination, the number of spikelets and the weight of spikelets should be positively selected.
