Abstract

The study`s aim was to assess the phenotypic diversity of bulb traits (shape index, diameter, height and weight) in 15 red onion landraces grown in saline areas of south western TimişCounty. In this region growers use mostly red onion landraces with a high adaptability to specific environmental conditions determined by the abiotic stress factors, including soil salinity. The obtained results showed that significant differences in bulb traits were present between the landraces. This study found that the diversity of the studied red onion landraces was distributed within, as well as among landarces from the same location. Some of the landraces like Sânmartinu S. 18, Livezile 151, PeciuNou 99 and Uivar 305 with favorable traits could be selected for further research and utilization.
