| Abstract:
Lily (Lilium sp.) is a vegetatively propagated perennial and one of the most economically important of flower bulbs. Lily is cultivated worldwide as cut flower, garden flower and potted plant. Lilies are the aristocrats of the garden and are very popular due to their elegant flowers and stately enormous habits they offer to gardeners in range of colors, forms and fragrances. A breeding program was begun to obtain new varieties with a wide range of colors. In the trial, the parent plants involved and the hybrids were evaluated individually. For each plant, starting with the anthesis of the first flower, the coloring was analyzed separately. In evaluating cultivars by color, the ‘Royal Horticultural Society Color Chart’ was used. Significant differences between and within combinations were detected. Color analysis allows conclusion on heredity of progeny traits. It was found that cultivars in orange-red [if selected as parents (‘Compass’, ‘Gran Paradiso’ and ‘Alisa’)] produced hybrids in orange-red as the dominant color over white, yellow and violet. In cross combination, ‘Olga’ (apricot-white with brown spots) x ‘Arabeska’ (salmon-orange), high variability was observed. As inherited from the female parent and considered the dominant traits, intermediates in shades of rosy-pink, apricot, salmon-orange with brown spots in the centres were observed. Hybrids similar to parents by color were produced by the Trumpet hybrid lilies in cross combination of ‘Zemgale’ (creamy white, unspotted) x ‘White Henryi’ (white with yellow-orange centres). Altogether 353 plants were estimated in 14 cross combinations. Of those cases, 41% showed co-domination over the corresponding traits of a cultivar and in color 36% were female and 23% male parents. | |
