Abstract
The implementationof breeding programsfor indoor vertical farms has been increasingto provide new varieties that have higher nutritional contentsand morphological traits fitted to thesesustainable production systems. Spinach (Spinacia oleraceaL.) is one of the fastest-growing, nutrient-dense leafy vegetables to grow indoors. In Vietnam, market demand for spinach is growing together with the expansion of soilless cultivation technologies such as hydroponics and vertical farming. This research aimed to evaluate the growth parameters, initially screening the relationship between yield and biological traits,of 12 spinach varieties. In addition, this research also aimed to evaluate the lutein, vitamin C, total flavonoid,and carbohydrate contentsin different varieties of spinach and theircorrelationswith morphological traits. The research outcomesrevealed significant positive correlations between plant weight and leaf area. Three spinach varieties belonging to the smooth leaf type (“AD”, “CH”,and“DT”)were the top three yielding under low light conditions. There were significant differences in the lutein content among varieties. “Red” and “Mikado” werethetwo highest varieties for lutein content. Vitamin C and total flavonoid contentswere statistically similar in the tested varieties, while the carbohydrate content was slightly different among them. This research firstly suggested better suited spinach varieties to be grown in vertical farmingconditions, and secondly, providedbreeders information on trait identifications to prepare breeding materials for vertical farms.
