Distant hybridization can expand genetic variations and is widely applied in plant breeding. Lycoris has high economic value, but the ornamental period is short. To prolong the florescence and leaf period of Lycoris, intergeneric hybridization between Lycoris and Clivia was conducted. The offspring bloomed 7–8 years after sowing. The characteristics of the offspring were observed from three dimensions: annual growth rhythm, morphological feature, and foliage anatomy structure. The hybrids were similar to the maternal plants (L. haywardii) with some variation, but did not show any paternal (C. nobilis) characteristics. The hybrid was identified by molecular marker, only a few paternal bands were amplified. The intergeneric hybrid exhibited absolute unilateral parent dominance that was few reported. This study offers innovative insight into the characteristics of distant hybrids.

远缘杂交可以扩大遗传变异，广泛应用于植物育种。石蒜经济价值高，但观赏期短。为延长石蒜的花期和叶期，对石蒜和君子兰进行了属间杂交。播种后7-8年，后代开花。从年生长节律、形态特征、叶片解剖结构三个维度观察后代的特征。杂交种与母本植物 ( L. haywardii )相似，但有一些变异，但没有显示任何父本植物 ( C. nobilis)） 特征。通过分子标记鉴定杂种，仅扩增出少量父本条带。属间杂种表现出很少报道的绝对单边亲本优势。这项研究提供了对远缘杂交种特征的创新见解。
