Botrytis cinerea resistance in tomato

Lobo, M. R. Navarro, A. Bernal,and L.M.Llano.

Tomato fruit mold (Botrytis cinerea) resistance was tested in 41 different cultivars by puncture inoculating fruits (9 puchtures per fruit) , with 1 x 10^6^ spores/ml of the fungus. Scoring was done in humid chamber 48 and 96 hours after inoculation. The accession PI 119214 exhibited the lowest symptoms; fruits did not exhibit advance of the disease one week after inoculation (Table 1).
