Abstract
P. bjoerlingii, the perfect stage of Phoma betae, developed on seedstalks of sugar beet [Beta vulgaris] after inoculation of the flowering plants with conidia of Phoma betae following harvest, and exposure of the seedstalks outdoors. Single-ascospore isolates were more virulent than a standard Phoma isolate on genotypes developed for storage-rot resistance. The Pleospora stage was found on sugar beet seedstalk stubble in the Salem, Oregon [USA], area where most of the seed used by the USA sugar beet industry is produced.This publication has 0 references indexed in Scilit:
