Evaluation and conservation of germplasm resources of solanum melongena l. owned by plant genetic resources bank buzau

Plant Genetic Resources Bank (PGRB) Buzau holds a valuable collection of eggplant (Solanum melongena L.) genotypes consisting of 286 genotypes. Of these, 62 genotypes are genetically stabilized, 86 genotypes are in an advanced stage of breeding, and 138 genotypes are in the segregating or recently introduced category, which are not sufficiently known in terms of character expression and stability in the lineage. In the present work, 62 genetically stabilized lines, mainly composed of local populations and old traditional varieties, were studied. During the growing period phenological, biometric observations and laboratory analyses were made using UPOV and IGPRI guidelines. Regarding productivity and resistance to the main pathogens, especially Verticillium wilt, it was found that the old local populations were the most vigorous and productive.
