摘 要: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。

Asiatic cultivars,12 of them(‘Eleganza’,‘Monte Negro’,‘Renoir’,‘Black Bird’,‘Butter Pixie’,
‘Orange Matrix’,‘Petit Brigitte’,‘Pink Pixie’,‘Lollypop’,‘Red Latin’,‘Marrakech’,and
‘Pollyanna’)are diploid(2n = 2x = 24),five of them(‘Navona’,‘Orange Pixie’,‘Elodie’,‘Vermeer’
and‘Lyon’)are triploid(2n = 3x = 36),the rest four(‘Brunello’,‘Tresor’,‘Val di Sole’and‘Detroit’)
are tetraploid(2n = 4x = 48). All the three Longiflorum lilies(‘White Heaven’,‘Gelria’and‘White
Fox’)are diploid(2n = 2x = 24). All seven Oriental lilies(‘Siberia’,‘Sorbonne’,‘Maru’,‘Dynamite’,
‘Dordogne’,‘Montezuma’and‘Miss Lucy’)are also diploid(2n = 2x = 24). The eight LA hybrids
(‘Brindis’,‘Courier’,‘Pavia’,‘Advantage’,‘Mestre’,‘Mombasa’,‘Pirandello’and‘Serrada’)
are all triploid(2n = 3x = 36). Two LO hybrids(‘Triumphator’and‘White Triumph’)are also triploid
(2n = 3x = 36). Among the four OT hybrids,‘Yelloween’and‘Red Dutch’are diploid(2n = 2x = 24),
while‘Conca D’Or’and‘Golden City’are triploid(2n = 3x = 36). The results show that most of the lily
cultivars from intra-section hybridization(i.e.,Asiatic,Oriental and Longiflorum lilies)are diploid except
for five triploid and four tetraploid Asiatic lilies,by contrast,nearly all lily cultivars from inter-section
hybridization(i.e.,LA,OT and LO)are triploid except for two diploid OT cultivars.

百合为重要的球根花卉,栽培品种多源于百合属的组内或组间杂交,其中组内杂交品种群主要
有亚洲百合(Asiatic lilies,A)、麝香百合(Longiflorum lilies,L)、喇叭百合(Trumpet lilies,T)
和东方百合(Oriental lilies,O),而组间杂交品种群有 LA(Longiflorum × Asiatic)、OT(Oriental ×
Trumpet)、LO(Longiflorum × Oriental)和 OA(Oriental × Asiatic)等。尽管我国有比较丰富的百
合野生资源(梁松筠 1995),但在新品种培育方面同荷兰相比相距甚远。培育具有自主知识产权的
百合品种是当前我国百合产业发展的一个重要方向。
在百合杂交育种中,知道亲本的染色体倍性对杂交成功与否非常重要。有关野生百合的染色体
倍性、常规核型及 C 带和以 rDNA 为探针的 FISH 核型已多有报道(Stewart,1947;图立古尔 等,
1996;Lim et al.,2001;王树红 等,2007;周树军 等,2008;胡凤荣 等,2009;刘冬云 等,2009;
荣立苹 等,2009)。这些报道表明除卷丹具有三倍体(2n = 3x = 36)的类群外,其余皆为二倍体(2n =
2x = 24)。然而,对百合栽培品种染色体倍性的报道仅限于一些二倍体品种(孙晓梅 等,2010)。
事实上,现在市场上的百合品种不仅数量多,而且既有二倍体,也有三倍体和四倍体,其中通过
麝香百合和亚洲百合杂交推出的品种多为三倍体(Zhou et al.,2008a)。由于百合染色体倍性从外
观上难以准确判断,因此,作者对目前国内市场出现的 45 个品种进行了倍性分析,供百合育种工
作参考。
1 材料与方法
1.1 材料来源
45 个百合品种均为从荷兰引进的品种,其中 21 个亚洲百合(A)品种、3 个麝香百合(L)
品种、7 个东方百合(O)品种、8 个 LA 杂交品种、2 个 LO 杂交品种和 4 个 OT 杂交品种。39
个品种购买自浙江虹越花卉有限公司,5 个由云南省农业科学院花卉研究所提供,1 个由北京农学
院提供(表 1)。

1.2 染色体制片
染色体分析采用常规压片法。待试管苗的根或温室栽培百合的茎生根约 1 ~ 3 cm 长时切下并用
蒸馏水清洗干净,再用 0.7 mmol · L-1 的放线菌酮室温预处理 4 h,然后用酒精︰乙酸(体积比 3︰1)
固定 12 h 后备用;将固定好的根尖用 1%的纤维素酶和果胶酶混合液软化后,用 2%醋酸洋红染色,
压片后用 Olympus(BH-2)观察,并对较好的中期分裂相照相以便对染色体进行计数。
2 结果与分析
在 21 个亚洲百合品种中,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(‘White Heaven’、‘Gelria’和‘White Fox’)都为二倍体(2n = 2x = 24)。
7 个东方百合品种(‘Siberia’、‘Sorbonne’、‘Maru’、‘Dynamite’、‘Dordogne’、‘Montezuma’
和‘Miss Lucy’)也都为二倍体(2n = 2x = 24)。
8 个 LA 杂交品种(‘Brindis’、‘Courier’、‘Pavia’、‘Advantage’、‘Mestre’、‘Mombasa’、
‘Pirandello’和‘Serrada’)皆为三倍体(2n = 3x = 36)。
两个 LO 杂交品种(即:‘Triumphator’和‘White Triumph’)都为三倍体(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)(表 1,图 1)。
该结果表明,组内品种(亚洲百合、东方百合和麝香百合)中,除亚洲百合中有三倍体和四倍
体品种,其余均为二倍体品种,因而组内品种主要为二倍体品种;然而,组间杂交品种(LA、OT
和 LO),只有 OT 百合的‘Yelloween’和‘Red Dutch’为二倍体品种,其余皆为三倍体品种,因此,
组间杂交品种三倍体占绝对优势。
3 讨论
由于不同组百合的农艺性状具有较大差异,如:亚洲百合花色丰富,花朵朝上,较抗病毒和枯
萎病;东方百合香气甜美,较抗灰霉病;麝香百合易于促成栽培,因此,培育组间杂交品种是百合
育种的一个重要方向。同时,由于多倍体同二倍体相比较在器官大小和生长势方面具有较大的优势,
因而,百合多倍体育种也是重要的方向。
百合组间杂交的 F1 代通常由于减数分裂不正常而高度不育(Zhou et al.,2008b),但有些可以
产生少量体细胞配子(2n 配子),从而产生三倍体的回交一代,这一过程称作有性多倍化
(Barba-Gonzalez et al.,2004,2005a,2005b),用基因组荧光原位杂交技术可证明荷兰百合育种公
司通过有性多倍化从回交一代中筛选了很多三倍体 LA 品种(Zhou et al.,2008a)。因此有理由相信
本试验中的 LA、OT 和 LO 三倍体品种可能主要来源于有性多倍化。
当然,本试验中的有些三倍体也可能来源于无性多倍化的途径,即:在百合育种中通常用安磺
灵对不育的 F1 代加倍使其恢复育性,然后再与二倍体回交获得三倍体(van Tuyl,1989;van Tuyl et
al.,1992)。
有性多倍化比无性多倍化有更多的优势:第一,有性多倍化大大缩短了百合的三倍体育种年限;
5 期 李克虎等:百合品种染色体倍性观察 973

第二,有性多倍化中 F1 产生的体细胞配子有基因组间染色体重组,从而大大增加了 2n 配子变异,
提高了后代筛选的机会(Ramanna & Jacobsen,2003)。这也正是市场上有较多三倍体组间杂交品种
的原因。
