Abstract

Lily is a popular flower, it can be used as cut flower and potted plant. It has colorful flower, long vase life and fragrance. This research was conducted to study the crossability of potted, cut flower and native lily. Morphology of 8 varieties of cut flower, 8 varieties of potted lily, and one native species, Lilium primlinum Baker var. burmanicum Stearn was conducted. Self- and cross- pollinated among cut flower, potted and species as well as reciprocal cross, were made. The results showed that characteristics such as plant height, leaf shape, flower and flowering period of each variety in this study were different. Chromosome number of Buzzer, Tiny Bee, Tiny Invader, Tiny Rocket, Sheer Blonde, Sunny Martinique, Sunny Bahamas, Sunny Robyn, Praiano and native lily was 2n = 24 whereas those of Nashville, Nova Zembla, Corcovado, Imprato, Redford and Saronno was 2n = 36 and Caesars Palace was 2n = 48. Self-pollinated could be made in six crosses and cross-pollinated within potted lily could be made in 30 crosses. Whereas cross-pollinated within cut flower lily could be done in 19 crosses. Cross-pollinated between potted and cut flower lily could be done in 20 crosses and reciprocal were 37 crosses. Lastly, crosses between potted and cut flower lily with Lilium primulinum Baker var. burmanicum Stearn could be made in 7 crosses. Seed germination was found in three variety and one species of self-pollinated cross and 49 crosses of cross-pollinated and reciprocal cross of potted lily, cut flower lily groups, and Lilium primulinum Baker var. burmanicum Stearn.
