随着克字号小麦品种的更替，产量大幅度提高，其产量性状发生了明显的变化。具体体现在：单株产量、株粒数、千粒重增加，株高变矮；品质性状呈现高低高的“Ｖ”型变化趋势。说明９０年代我所在品种选育上基本实现了高产和优质的结合。从克字号小麦品种演进规律和关联度分析可以明确，今后克字号小麦高产育种的目标为：在保持千粒重的基础上增加穗粒数，或在保持穗粒数的基础上增加千粒重。
With the replacement of K-type wheat varieties, yield increased significantly, and its yield traits have undergone significant changes. The concrete manifestation is that the yield per plant, the number of grains per plant, the increase of 1000-grain weight and the shortened plant height, and the quality traits showed the “V” type of high and low variation trend. This shows that in the 90’s, the breeding of my own species basically achieved the combination of high yield and high quality. From the K type wheat varieties evolution and correlation analysis can be clear, the future K-type wheat high-yielding breeding objectives are: to maintain the 1000-grain weight increase based on the number of grains per spike, or increase the number of grains per thousand based on the increase of 1000-grain weight.
