摘要
供试的24个Maris 和TJB 英国小麦系列品种分别含有抗我国小麦条锈病菌已知生理小种的Yr1,Yr2,Yr3a,Yr3b,Yr4a,Yr4b,Yr6,Yr13,Yr14和Yr16中的若干个基因。有的品种含Yr基因数仅有2个,有的多达5个。此外,还含有抗白粉病Pm_2或Pm_2Pm_6基因。这是当前我国黄淮海麦区条锈病和白粉病较为理想的抗源。
The Maris and TJB set wheat varieties from the Britain carry Yr1,Yr2,Yr3a,Yr3b,
Yr4a,Yr4b,Yr6,Yr13,Yr14 and Yr16 genes respectivehy,which show good resistance to races of
stripe rust in wheat region of china.They also carry Pm_2 or Pm_2Pm_6 genes.They are ideal sources
for resistance to stripe rust and powdery mildew in Huang-Huai-Hai Wheat region recently.
