Abstract:

In order to study the population structure and yield formation characteristics of two-line hybrid wheat, a comparison of 142 hybrid wheat combinations on dynamics of plant population quantity and yield components was conducted under field condition using common wheat as the control. The results showed that two-line hybrid wheat yield showed obvious advantages and could increase the yield by as much as 17.3%, the percentage of increased combinations compared to all of the tested combinations was 27.5%. Hybrid wheat had a prominent advantage of tillering and the tillering peak mainly occurred before wintering, and it was helpful to construct a reasonable population basis by promoting the tillering of hybrid wheat before winter. Since spike number and 1000-grain weight contributed significantly to the yield, it was important to further tap the potential of spike number to expand sink capacity and to realize more significant increase. In order to further improve the yield of hybrid wheat, we should focus on the combination selection with good characteristics of higher sink capacity and stronger recoverability.

Key words: Two-line hybrid wheat, Population structure, Yield formation
