以常见的15个东方百合×喇叭百合(OT百合)品种和14个东方百合品种为材料,通过花粉离体萌发及常规柱头授粉,研究OT百合的花粉活力及其与东方百合雌配子的亲和性;同时,以这15个OT百合品种为母本,以‘布莱斯卡’、‘蒙特祖玛’和‘圣坦德’3个东方百合品种为父本,采用常规柱头授粉研究OT百合雌配子的育性.结果表明:(1)OT百合品种‘宇宙山’和‘入侵’的花粉具有低频率的活力(花粉萌发率分别为5%和6%),其他13个OT百合品种的花粉基本没有活力;(2)‘宇宙山’的花粉与东方百合品种‘卡西尼’、‘居里’、‘凯里湖’的雌配子具有一定亲和性;(3)‘入侵’的花粉与东方百合品种‘吉瑞斯’、‘科德萨’的雌配子具有一定亲和性;(4)除‘可可茶’、‘曼妮莎’、‘震动’和‘耶罗林’4个OT百合品种外,其他11个OT百合品种的雌配子均具有一定程度的育性.
The pollen vitality of OT lily and its affinity with the female gamete of oriental lily were studied by in vitro pollen germination and conventional stigma pollination with 15 common oriental lily × lily bulbs (OT) and 14 oriental lily varieties as materials In the meantime, using the 15 OT lily varieties as the female parent and 3 Oriental lily varieties of ’Blaiseka’, ’Montezuma’ and ’Santander’ as the male parent, Fertility of gametes: The results showed that: (1) The pollen of OT lily ’cosmos’ and ’invader’ had low frequency activity (pollen germination rate was 5% and 6% respectively), pollens of other 13 OT lily varieties (2) The pollen of ’Cosmos Mountain’ has some affinity with the female gametes of ’Cassini’, ’Curie’ and ’Lake Carey’ of Oriental lily varieties; (3) The ’invasive’ pollen There is a certain affinity with the female gametes of oriental lily varieties ’Ji Ruisi’ and ’Codessa’; (4) In addition to 4 coco tea, ’Manisa’, ’Shakes’ and ’Er Luo Lin’ OT lily varieties, the other 11 OT lily varieties of female gametes have a certain degree of fertility.
