摘要
The genetics of powdery mildew (Erysiphe pisi) resistance in pea (Pisum sativum) was studied using five isolates of E. pisi in a controlled environment. Resistance was controlled by a single recessive gene in all the pea cvs. included in the study. The same recessive gene controlled resistance to all the five isolates of E. pisi. Tests for allelism showed that resistance in cvs. HPPC-63, HPPC-95, DPP-26, DPP-54, Mexique-4, SVP-950, Wisconsin-7104 and P-6588 is conferred by the same recessive gene.
