利用染色体常规制片技术分析了45个从荷兰引进的百合品种的染色体倍性,包括21个亚洲百合、3个麝香百合、7个东方百合、8个LA杂交品种、2个LO杂交品种、4个OT杂交品种。在21个亚洲百合中,12个品种(’Eleganza’、’Monte Negro’、’Renoir’、’Black Bird’、’Butter Pixie’、’Orange Matrix’、’Petit Brigitte’、’Pink Pixie’、’Lollypop’、’Red Latin’、’Marrakech’和’Pollyanna’)为二倍体(2n=2x=24),5个品种(’Navona’、’Orange Pixie’、’Elodie’、’Vermeer’和’Lyon’)为三倍体(2n=3x=36),4个品种(’Brunello’、’Tresor’、’Val di Sole’和’Detroit’)为四倍体(2n=4x=48);3个麝香百合品种(’White Heaven’、’Gelria’和’White Fox’)为二倍体(2n=2x=24);7个东方百合品种(’Siberia’、’Sorbonne’、’Maru’、’Dynamite’、’Dordogne’、’Montezuma’和’Miss Lucy’)为二倍体(2n=2x=24);8个LA杂交品种(’Brindis’、’Courier’、’Pavia’、’Advantage’、’Mestre’、’Mombasa’、’Pirandello’和’Serrada’)为三倍体(2n=3x=36);两个LO杂交品种(’Triumphator’和’White Triumph’)为三倍体(2n=3x=36);4个OT杂交品种中’Yelloween’和’Red Dutch’为二倍体(2n=2x=24),’Conca D’Or’和’Golden City’为三倍体(2n=3x=36)。该结果表明,组内杂交品种(亚洲百合、东方百合和麝香百合)中,除亚洲百合中有5个三倍体和4个四倍体品种外,其余22个为二倍体品种,因而多数组内杂交品种为二倍体品种;而组间杂交品种(LA、OT和LO),只有OT中2个品种为二倍体,其余12个皆为三倍体。
Chromosome ploidy of 45 lily varieties introduced from the Netherlands was analyzed by conventional chromosome production techniques, including 21 Asian lilies, 3 musk lilies, 7 Oriental lilies, 8 LA hybrids, 2 LO hybrids, 4 OT hybrids. Among the 21 Asian lilies, 12 varieties (’Eleganza’, ’Monte Negro’, ’Renoir’, ’Black Bird’, ’Butter Pixie’, ’Orange Matrix’, ’Petit Brigitte’, ’Pink Pixie’, ’ (2n = 2x = 24), 5 varieties (’Navona’, ’Orange Pixie’, ’Elodie’, ’Vermeer’, and ’Pollyanna’) from Lollypop ’,’ Red Latin ’,’ Marrakech ’and’ Pollyanna ’ Lyon ’was triploid (2n = 3x = 36) and tetraploid (2n = 4x = 48) in 4 cultivars (’ Brunello ’,’ Tresor ’,’ Val di Sole ’and’ Detroit ’ Four white lily varieties (’White Heaven’, ’Gelria’ and ’White Fox’) were diploid (2n = 2x = 24); seven Oriental lily varieties (’Siberia’, ’Sorbonne’, ’Maru’ (2n = 2x = 24); 8 LA hybrids (’Brindis’, ’Courier’, ’Pavia’, ’Advantage’, ’Courier’, ’Dordogne’, ’Montezuma’ and ’Miss Lucy’ (2n = 3x = 36); the two LO hybrids (’Triumphator’ and ’White Triumph’) were triploid (2n = 3x = 36); ’Yelloween’ and ’Red Dutch’ were diploid (2n = 2x = 24) and ’Conca D’Or’ and ’Golden City’ were triploid (2n = 3x = 36). The results showed that among the hybrids (Asian lily, Oriental lily and Musk lily), in addition to 5 triploidy and 4 tetraploid varieties in Asian lily, the other 22 were diploid varieties, and the majority The crosses in the crosses were diploid, while in the cross between the crosses (LA, OT and LO), only two of OT were diploid and the remaining 12 were all triploid.
