[目的]研究双子叶植物种子发芽时数量性状的遗传规律,可为作物品质改良提供理论依据。[方法]7个丝瓜品种不完全双列杂交F1和亲本种子在不同环境下进行发芽试验,采用适合于双子叶植物的包括环境互作效应的二倍体胚遗传模型进行分析。[结果]根长、苗长和苗干重3个性状均同时受胚遗传效应和遗传与环境互作效应的影响。胚显性效应是根长和苗长的主要遗传效应。对于环境互作效应,胚显性与环境互作效应是3个性状的主要遗传效应。苗长和苗干重的狭义遗传率分别是7.0%和27.3%。[结论]采用二倍体胚遗传模型符合双子叶植物种子发芽时期幼苗生长发育的遗传基础,可用于亲本选择和耐性品种选育研究。

[Objective] The research aimed to understand the genetic control of seed germination characters in dicotyledon plant using a suitable genetic model. [Method] An investigation of three seedling traits of seven parents and their F1s was undertaken in a diallel cross of sponge gourd （Luffa cylindrical Roem.） by germinating the seeds in two environments. A genetic model is developed to analyze the embryo effects as well as genotype × environment （GE） interaction effects of germination characters. [Result] Variations of the root length, shoot length and shoot dry weight were affected by genetic effects and environmental interaction effects. The three seedling traits were mainly controlled by genetic effect. Embryo dominance effects were the main genetic effect for root length and shoot length. Among the GE interaction effects, there only existed embryo dominance interaction effects for the three seedling traits. General narrow-sense heritabilities of shoot length and shoot dry weight were 7.0% and 27.3%, respectively. [Conclusion] The present modified genetic model could be used for investigating the genetic control of seed germination characters and seedling traits in dicotyledon plant.
