以农大139等7个冬小麦品种进行4×3不完全双列杂交，采用加性-显性及其与环境互作的遗传模型对亲本、F_1和F_2的株高、主穗穗长、单株穗数、主穗小穗数、千粒重和单株粒重6个性状进行遗传分析．结果表明，株高和主穗长主要受加性效应控制，而单株穗数、主穗小穗数、千粒重和单株粒重主要受显性×环境互作效应影响．矮2杂交后代易选到矮株，奥里生杂交后代易得到大穗材料，农林10号和奥里生的杂交后代分蘖力将加强，814的杂交后代小穗数增多，814杂交后代千粒重增高．所有产量性状未表现明显的杂种优势．
A total of 7 winter wheat cultivars, including Nongda 139, were used for 4 × 3 incomplete diallel crosses. Based on additive-dominance and their interaction with environment, the plant height, Spike number, spike number per spike, 1000-grain weight and grain weight per plant were analyzed. The results showed that the plant height and the main spike length were mainly controlled by the additive effect. The number of spikes per panicle, the number of spikelets per spike, the weight of 1000 spikelets and the grain weight per plant were mainly affected by the effects of dominant × spatiotemporal interactions. Shorter 2 hybrids are easy to select the dwarf plants, Orisheng hybrid progeny easy to get big spike materials, Nonglin10 and Orisheng hybrid progeny to enhance tillering ability, 814 hybrids increased spikelet number, 814 hybrids increased grain weight . All yield traits did not show significant heterosis.
