The genetic improvement programme on the cherry tree at the Julius Kühn-Institut (JKI) has an almost century-long tradition. The first activities were started by M. Schmidt in Müncheberg in the 1930s. Later, M. Zwitzscher continued the project at the Max Planck Institut in Cologne by propagating the varieties Primavera and Sekunda, while E.L. Loewel in Jork selected and propagated a dozen varieties, including Regina.
More recently, in Dresden, M. Fischer started a new breeding programme aimed at self-fertility and resistance to bacterial cancer by Pseudomonas spp, leading to the release of the NA series varieties Namosa, Nadina, Namare and Namati.
Since 2001, the project has been in the hands of M. Schuster at the JKI in Pillnitz. The cherry varieties Narana (ripens with Burlat), Swing® PiSue 192* (+8 Burlat), Polka (+10 Burlat), Aria® PiSue 161 (+14 Burlat), Areko (+17 Burlat), PiSue 177 (+19 Burlat) and Habunt, a two-coloured cherry ripens 20 days after Burlat.
Below the report of Mirko Schuster presented at the workshop on cherry variety innovation at Macfrut 2023.

The start of the harvest, originally scheduled for May 20th, will be compromised by the impending losses due to prolonged rains and low temperatures for the season, while late varieties, with a delay in ripening, seem to have been saved for the moment.

Tests conducted with needles of 3 different sizes showed that the best product diffusion occurred with the longest needle. Subsequently, the researchers started trials directly in the field. The first study focused on the healing time of the injection sites.

A study on ‘Meizao’ sweet cherries shows that foliar 5-ALA at 100 mg/L increases fruit weight, color, sugars, nutraceutical compounds and aroma complexity by improving photosynthetic efficiency and stimulating the biosynthesis of secondary metabolites in the fruit itself.

A 12.5% US tariff on Chilean cherries is squeezing margins and slowing diversification beyond China. Exporters are responding through bilateral talks, more efficient logistics, premium-grade fruit and faster growth in Vietnam, India, Indonesia and South Korea in 2026.
