在田间研究中,具有Sr6基因的小麦品系通常比那些没有这个基因的品系杆锈发展较慢。当温度在24℃波动时或多个毒性基因存在于杆锈菌群体中时,Sr6基因和其它微效基因结合控制慢锈性。估算遗传率,表明这种慢锈特性能够结合到育种的群体中去。寄主植株旗叶上杆锈菌扩展的组织观察表的,Sr6基因的最大作用是能阻止病菌在完成侵入后的生长。 In field studies, the wheat lines with the Sr6 gene usually developed slower than those with no such line. The Sr6 gene binds to other minor genes to control slow-rusting when the temperature fluctuates at 24 ° C or multiple toxic genes are present in the P. rust population. The heritability is estimated, indicating that this slow-rusting trait can be incorporated into the breeding population. The dominant role of the Sr6 gene in the expanded histological observation of the rod rust on the flag leaf of the host plant is to prevent the pathogen from growing after its invasion.
