Genetic population structure and fungicide resistance of Botrytis cinerea in pear orchards in the Western Cape of South Africa

Wessels, Bernard A.; Linde, Celeste; Fourie, P.H.; Mostert, Lizel


Botrytis cinerea isolates from pear blossoms (Pyrus communis) in South Africa were collected from four orchards in two production areas in the Western Cape. The cryptic species status based on vegetative-incompatibility alleles of the Bc-hch gene indicated that all the isolates belonged to B. cinerea. A microsatellite analysis of B. cinerea populations was performed to assess the genetic population structure. Total gene diversity (H) was high, with a mean of 0.69 across all populations. Some...[Show more]
