<strong>Post</strong><strong>harvest</strong> Disease Summary 329<br />

of the nor mutant (Barkai-Golan <strong>and</strong> Kopeliovitch, 1989; Lavy-Meir et<br />

al., 1989), which is characterized by color development <strong>and</strong> retarded<br />

softening (Tigchelaar et al., 1978). This resistance was, however,<br />

partially broken when the fruit was exposed to chilling temperature or<br />

hot water treatment, which favor fungal penetration (Barkai-Golan <strong>and</strong><br />

Kopeliovitch, 1989).<br />

Some cultivars of solanaceous <strong>fruits</strong> are available, which are resistant<br />

to certain post<strong>harvest</strong> pathogens. They include tomato <strong>and</strong> pepper<br />

cultivars resistant to various Phytophthora spp. causing fruit rot, tomato<br />

cultivars resistant to P. infestans <strong>and</strong> eggplant cultivars resistant to<br />

Phomopsis (Snowdon, 1992).<br />
