为了研究小麦株高与赤霉病抗性等表型的相关性，以兰天33号为对照，在自然发病条件下，选用甘肃省陇南片区域试验及生产试验中的16个小麦品种(系)，研究了供试小麦抗赤霉病性与株高间的相关性。结果表明，株高对赤霉病的抗性影响较大，植株较高材料抗性相对较强，兰天48号尽管株高较低，但抗病性也较强。

In order to study the correlation between plant height and Fusarium head blight(FHB) of wheat, the correlation between FHB and plant height of 16 wheat varieties(lines) in the Longnan regional experiment and production experiment of Gansu Province was studied under natural disease conditions with Lantian 33 as control. The results showed that the plant height had a great influence on the FHB resistance. The higher the plant was, the stronger the resistance was. Although the plant height of Lantian 48 was lower, the resistance was also stronger.
