Thirty-nine wheat genotypes were studied to estimate their partial resistance levels to leaf rust at Behira governortae during three growing seasons, i.e. 2016/2017, 2017/2018 and 2018/2019. In these genotypes, partial resistance was characterized using final leaf rust severity (FRS %) and area under disease progress curve (AUDPC). Of the tested genotypes, only three wheat varieties; Giza 171, Misr 3 and Sohag 5 showed complete resistance. Further, 28 of the 39 genotypes had partial resistance as they revealed low and/or moderate values of FRS (%) and AUDPC (not exceeding 30% and 300, respectively). The other eight varieties were fast rusting, as they displayed the maximum values of FRS (%) and AUDPC. The four monogenic lines; Lr 34, Lr 46, Lr 67 and Lr 68 were identified in the wheat varieties using linked molecular markers; csLV34, Xgwm259, CFD71 and csGSR. Phenotypic results of the wheat varieties were confirmed by molecular marker analysis.

成年植物抗性基因Lr 34，Lr 46，Lr 67和Lr 68的分子标记和表型特征以及与小麦抗叶锈病的部分抗性相关。

研究了39个基因型的小麦，以估计其在三个生长季节，即2016 / 2017、2017 / 2018和2018/2019期间对Behira Governorortae的叶锈病的部分抗性水平。在这些基因型中，使用最终叶锈病严重程度（FRS％）和病情进展曲线下面积（AUDPC）来表征部分抗药性。在测试的基因型中，只有三个小麦品种。Giza 171，Misr 3和Sohag 5显示完全抵抗。此外，39个基因型中的28个具有部分耐药性，因为它们显示出FRS（％）和AUDPC的低和/或中值（分别不超过30％和300）。其他八个变种快速生锈，因为它们显示了FRS（％）和AUDPC的最大值。四个单基因系；使用连锁分子标记鉴定出了小麦品种中的Lr 34，Lr 46，Lr 67和Lr 68。csLV34，Xgwm259，CFD71和csGSR。通过分子标记分析证实了小麦品种的表型结果。
