Phenotypic stability of strawberry cultivars based on physicochemical traits of fruits
ABSTRACT Strawberry shows genetic variability between cultivars and, environmental elements affect the physicochemical traits of fruits when assessed under different environments. So, assessment of the stability of physicochemical traits is a tool that assists the producer in the choice of the cultivar with higher acceptance in the consumer market. This study aimed to assess the stability of strawberry cultivars based on physicochemical traits of fruits on three environments using the additive main effects with multiplicative interaction (AMMI) analysis. Thirteen strawberry cultivars were assessed in Lavras-MG, Uberlândia-MG, and Guarapuava-PR. The experimental design was in blocks with treatments at random and four replications. The stability of physicochemical traits of fruits (firmness, soluble solids, titratable acidity, soluble solids to titratable acidity ratio, vitamin C, and anthocyanins) was assessed. For the stability and performance of physicochemical traits under the three environments, the cultivars Tudla and Festival stood out for fruit firmness, Albion for soluble solids, Aromas and Tudla for titratable acidity, Sweet Charlie and Palomar for soluble solids to titratable acidity ratio, and Camarosa for vitamin C and anthocyanins.
