In order to use wild lily resources for new cultivar breeding, the cross compatibilities of partial wild lilies were evaluated by self\|crossing, inter\|specific crossing and crossing between varied species and cultivars. Main results were obtained as follows: 1) the swollen fruit rates in selfing of Lilium pumila, L. laucanthum and L. regale reached 100％, 66.7％ and 11.1％ respectively. 2) When L. lancifolium, L. sargentiae, L. regale, L. davidii var. unicolor and L. tsingtauense were used as female parents, the average swollen fruit rates reached 53.1％,50.0％,50.0％,45.2％ and 20.0％ respectively. While as male parents, the average swollen fruit rates of L. regale, L. sargentiae and L. davidii were 50.0％, 35.0％ and 10.0％ separately. The results indicated that these several species were valuable for lily crossbreeding. 3) The compatibilities between species belonging to Sec.Leucolirion and cultivars of Oriental hybrids and Lilium×formolongi and those between species belonging to Sec.Sinomartagon and cultivars of Asia hybrids and Lilium×formolongi were higher; 4)The relationship between swollen fruit rate and the survival rate of ovary slices and hybrid seedlings indicates that the swollen fruit rate can be used as one of standards to show the cross compatibility among lily crosses.
