Physalis sp. is widely cultivated in South America, but little known and cultivated plant in Romania, although varieties belonging to the species are found in wild flora. The aim of this paper was to assess agronomic traits with emphasis on the phenotypic expressiveness of the accessions in terms of yield, quality and earliness production. The research consisted in agronomic evaluation of seven genotypes of Physalis (P. peruviana, P. ixocarpa, P. philadelphica and P. alkekengi) and the selection of valuable genotypes suitable for cultivation under the pedoclimatic conditions of the southern part of Romania. The study targeted 30 qualitative descriptors and 16 quantitative descriptors subjected to ANOVA analysis. A percentage of 67% of the studied genotypes contains fruits with a diameter exceeding 2 cm, belonging to the genus P. ixocarpa and P. philadelphica, 16.5% fall in the typical form of the Colombian ecotype of 1.85 cm, and 16.5% are small fruits, with a diameter below 1.5 cm. Accession A7 obtained a yield of 3.9 kg/plant and accessions A4 and A3 have small fruits, but with a higher content in soluble substances.
