采用完全双列条交法，研究了6个不同生态类型小麦品种幼穗分化特点及幼穗分化与产量构成因素的关系，并进行了遗传分析。结果表明：小麦不同生态类型间幼穗分化存在明显差异；各主要分化期对小麦产量构成因素及最终产量影响显著；提高小麦产量主要是通过协调幼穗各分化时期的长短来协调好穗、粒、重及其它性状的关系。
Using complete double-line bar crossover method, the relationship between spike differentiation and spike differentiation and yield components of six wheat cultivars with different ecological types was studied and the genetic analysis was carried out. The results showed that there were significant differences in spike differentiation between different ecotypes of wheat. The main differentiation stages had a significant effect on the yield components and the final yield of wheat. To improve the yield of wheat, the spikelets and grains , Heavy and other traits.
