Origin & Breeding History: 'Bassari' (experimental designation NUN 08224 LTL) was developed from an initial cross and successive controlled self-pollinations. The initial cross between two proprietary varieties was conducted in Gravenzande, Netherlands in 2013. The variety was advanced by continuous selfing from the F1 to the F7 generation in Gravenzande, Netherlands and selection was based on plant shape, bolting resistance, and disease resistance. In 2019, NUN 08224 LTL was selected and designated as 'Bassari'.

Tests & Trials: The detailed description of 'Bassari' is based on the UPOV report of Technical Examination, application number SLA4336, purchased from the Naktuinbouw in Roelofarendsveen, Netherlands. The trial was conducted by the Naktuinbouw in Roelofarendsveen, Netherlands in 2020.
