The expression of general resistance to late blight (Phytophthora infestans) in potato leaves

Evidence for Host Mediation of Preinfection Stages of Phytophthora infestans on the Leaf Surface of Solanum phureja

“…Wilson and Coffey (1980) found that compared with a susceptible cultivar, fewer zoospores were able to penetrate epidermal cells of the resistant cultivar, Pimpernel. In contrast, other studies found no difference between susceptible and resistant cultivars for preinfection processes (Hohl and Suter, 1976; Berggren et al., 1988; Gees and Hohl, 1988). Berggren et al.…”

Berggren et al. (1988) observed that studies which have detected a relationship between host resistance and preinfection processes used the resistant cultivar, Pimpernel, and suggested this cultivar may have an unusual resistance to penetration.…”

Antifungal activity toPhytophthora infestans of sesquiterpenoids from infected potato tubers

“…Bintje) at 15 ~ in darkness in a moist chamber. The inoculation of potato tuber slices was made according to Berggren et al (1988).…”

Change of reactions on late blight resistance in potato varieties from 1983 to 2011 in Hokkaido

“…．過去には，効果が高く導入が比較的容 易な真性抵抗性が用いられていた．しかし疫病菌の系統 の変化のために短期間で抵抗性が打破されるので，現在 では，より持続的な圃場抵抗性が主に用いられている (Wastie 1991, Akino et al 2014) ．しかし，圃場抵抗性品種 「マチルダ」 (Berggren et al 1988)の抵抗性が北海道にお いて 1998 年頃より低下した例があり (Kato et al 2001 1986-1989, 1991-1994, 1996-…”
