The objective of this study was to evaluate the quality of strawberry cultivars and clones, and their potential for storage under refrigeration. The experimental design was a randomized block design with four replicates of approximately 150 g each. The treatments consisted in the evaluation of three cultivars and four clones, namely: LBH 15.1 Arazá, SGH 140.3 Guenoa, LBF 236.3 Yvapitá, LBG 121.4, LBK 16.1, LBK 35.1 and LBK 28.1. Evaluations were made at harvest and after ten days of storage at -0.5ºC, plus two days at 20ºC. The parameters evaluated were firmness, acidity, soluble solids, TSS/ TTA ratio, ascorbic acid, presence of rotting and weight loss. In terms of quality, cv. Guenoa presented low acidity and high TSS e ascorbic acid, high TSS/TTA ratio and also showed better conservation, presenting low incidence of decay during storage. The cultivar LBF 236.3 Yvapitá and the clone LBK 28.1 showed the lowest vitamin C content and TSS/TTA ratio, which compromises its quality. The quick reduction of firmness and increased susceptibility to decay presented by LBF236.3 Yvapitá and LBK 28.1 show a low potential for conservation under refrigeration. Cultivars and clones that had higher quality at harvest, also showed better post-harvest conservation.
