LILY TRIAL IN THE LATVIA UNIVERSITY OF AGRICULTURE
Lilies, the aristocrats of the garden, are very popular for their elegant flowers and stately appearance, and offer an enormous range of colours, forms, and fragrances. In Latvia, breeders have worked mainly with Asiatic lilies. Martagons and Chinese trumpets have been extensively hybridized and the resulting cultivars found to be most suitable for gardens as well as landscape designs. The current research was aimed at creating a Lily Trial at the Latvia University of Agriculture to evaluate 100 species and cultivars under open environmental conditions. Lilies were evaluated according to their morphological characteristics: plant height, flower diameter and colour, inflorescence, number of flowers, as well as resistance to the grey mould caused by Botrytis spp. This fungus causes heavy losses as plants lose their attractiveness. The level of resistance to grey mould was rated visually in grades 0 to 4 (0=healthy, resistant to 4=very heavily susceptible). Ten plants were selected from each cultivar; their resistance was assessed and an average index of morbidity calculated. Plants were cultivated under field conditions and no fungicides were applied in the 2008 and 2009 seasons. This initial trial provided insight to the evaluation of resistance to grey mould and showed difference between tested lily cultivars and species under open environmental conditions in Latvia.
