Variety description

10 August 2026

The variety was developed in Italy as part of intensive breeding programs prior to the 1970s. It provided a yield increase of approximately 7% compared to previous varieties due to improvements in the harvest index and responsiveness to fertilizer application.

The literature also mentions the ISA-1 variety, selected in 1971 in Apulia. This variety was characterized by earliness, which allowed the plants to avoid the effects of drought stress.
