| Research Abstract |
Segregation analysis of self-incompatibility and -compatibility using BC1 population showed that self-compatibility is an inheritable character in Lilium longiflorum. A L. longiflorum cultivar showed partial self-compatibility was newly discovered. BA treatment on a pistil in self-incompatible L. longiflorum cultivars indicated that one of the factors of the failure of seed set in self-pollination is pistil senescence. There is significant genetic variation between the predominantly self-compatible population and predominantly self-incompatible population.
