The eggplant (Solanum melongena L.) is rich in vitamin P (also known as rutin), which is beneficial for humans. In this study, the vitamin P contents of 53 eggplant lines were measured via UV spectrophotometry. The results showed that the vitamin P content differed significantly among the eggplant lines and the actual contents of vitamin P in fresh fruit pulp and fresh peel were 0.18–0.82 mg · g⁻¹ and 0.42–2.32 mg · g⁻¹, respectively. Furthermore, the mixed major gene and polygene inheritance model method was used for the inheritance analysis of the vitamin P content in F₂ populations of three hybridization combinations. Inheritance analysis demonstrated that the vitamin P content of these eggplant lines was a quantitative trait. One or two major genes were the contributor, and the genetic effect was an additive-dominance effect. The high vitamin P content trait was regulated by the main gene and followed an additive effect. The heritability of the major genes controlling the high vitamin P content was low, while the heritability of the major gene that controls the low vitamin P content trait was high. These results provide a theoretical basis for the breeding of eggplants with high vitamin P content.

茄子（茄子茄）富含维生素P（也称为芦丁），对人体有益。在这项研究中，通过紫外分光光度法测量了53个茄子品系中的维生素P含量。结果表明，茄子品系之间的维生素P含量差异显着，新鲜果肉和新鲜果皮中的维生素P实际含量分别为0.18–0.82 mg·g ^-1和0.42–2.32 mg·g ^-1。此外，将混合主基因和多基因遗传模型方法用于F _2中维生素P含量的遗传分析。三个杂交组合的种群。遗传分析表明，这些茄子品系中的维生素P含量是定量特征。一个或两个主要基因是贡献者，遗传效应是加性优势效应。高维生素P含量的性状受主要基因调控，并具有加性效应。控制高维生素P含量的主要基因的遗传力较低，而控制低维生素P含量性状的主要基因的遗传力较高。这些结果为高维生素P含量茄子的育种提供了理论依据。
