Butler 1952 J Hered 43:25. Allelic to RCR3 |
Autogenous necrosis of leaves and stems, appearing first when the plants are 6-10 weeks of age as small, angular yellowish to brown, necrotic spots near the tips of the lower leaves; the spots are not superficial, but extend right through the leaf; accompanying the spotting is a downward and invward curling of the leaf; the spots become larger and coalesce and the necrosis proceeds upwards towards the growing point; the progress and severity of necrosis are greatly affected by environment -- under intense sunlight the plants may be completely browned, except near the growing point, their leaves largely shrivelled and dead; plants susceptible to Cladosporium fulvum are non-necrotic, the phenotype is only expressed with Cf-2 from S. pimpinellifolium and the S. lycopersicum allele of necrotic. |
