Genetic analysis of anthocyanin and vitamin C contents in lettuce

Abstract

Our investigation was based on viewing the problem of inheriting anthocyanin and vitamin C contents in F-1 progeny of lettuce. It was presumed that progenies with increased contents of these substances could be obtained. Diallel crossing of eight lettuce genotypes of different anthocyanin and vitamin C contents were performed. Parental and F-1 generations were investigated comparatively, and their mode of inheritance was determined. Concerning the inheritance of anthocyanin, dominant genes prevailed and a higher content of this substance was succeeded in F-1 generation, whereas concerning the inheritance of vitamin C content, it was recorded dominance mode of inheritance, when compared to the parents with lower vitamin C content. Apart from the dominance mode of inheritance, significant additive gene effects in inheriting vitamin C content were recorded.
