研究恶疫霉菌株ＳＢ－５和ＰＫ－９的生长速率、菌落形态和同宗配合等重要生物学性状在单游动孢子和单卵孢子后代的遗传。结果表明，上述性状在无性和有性单孢后代均可稳定遗传，认为供试恶疫霉菌株控制上述性状的遗传因子是纯合的。
To study the inheritance of the growth rate, colony morphology and homoelement and other important biological traits of P. acremonium strains SB-5 and PK-9 in single zoospores and single oospore progeny. The results showed that all of the above traits were stable and inheritable in both sexes and sexual monosodiums. It was considered that the genetic factors controlling the traits of P. xylostella were homozygous.
