摘要:
以克鲁兹王莲×'朗.伍德王莲自交后代'的58个子代为材料,观察分析了叶片卷边颜色、蕾形、萼片颜色、萼片着刺数、第一晚和第二晚花色等10个主要性状的分离情况,并对个体性状分离类型进行了聚类;结果表明,其后代性状分离极为广泛;主要表现为负向中亲优势、正向中亲优势和超亲优势;其中6个性状出现了超亲遗传现象。第一晚内瓣色、拟雄蕊尖色、第二晚内瓣色、第二晚外瓣色及第二晚内外瓣色差5个性状之间有高度或显著相关性,其余相关性较低,叶片卷边色、蕾形、萼片色、萼片着刺数及第一晚外瓣色5个性状独立遗传的可能大。个体性状分离类型丰富,主要可分为7大类,绿叶粉花白芯型、红叶玫红花白芯型、绿叶玫红花深玫红芯型、红叶玫红花深玫红芯型、绿叶深玫红花白芯型、红叶粉花深玫红芯型、绿叶萼多刺玫红花白芯型。

Abstract:
58 seedlings were obtained from the cross of Victoria cruziana with V. ‘Longwood Hybrid’ offspring, and the characteristics segregation of seedlings was studies and seedlings were clustered. The results showed that: the segregation of seedlings characteristics was wide range and show mid-parent heterosis and over-parent heterosis, there is transgressive inheritance in 6 characteristics; there were higher correlations in the first night inner petals color, the first night stamenoid color, the second night outer petals color, the second night inner petals color and the second night inner-outer shading, and lower correlations in rims color, buds type, sepals color, number of thorns on sepals and the first night outer petals color which most liked independent inheritance. The plants characteristics types were diversified, could be divided into 7 categories which were green leaves and outer pink-inner white flowers type, red leaves and outer fushcia-inner white flowers type, green leaves and outer fushcia-inner deep fushcia flowers type, red leaves and outer fushcia-inner deep fushcia flowers type, green leaves and outer deep fushcia -inner white flowers type, red leaves and outer pink-inner deep fushcia flowers type, green leaves and thorny sepals and outer fushcia-inner white flowers type.
