In 1985, a total of 60 wheat cultivars (lines) in Henan Province were identified. The results showed that resistance to stripe rust and stalk rust accounted for 58.3% and 50% of the identified varieties (lines), respectively; and leaf rust resistance accounted for 35% of the identified varieties. In addition, we also screened out many varieties (lines) that are also resistant to the three rust diseases, accounting for 15% of the identified varieties (lines). I.
