  Spring frost often damages green shoots in vineyards. This was the case on 25 April 2015 in Kecskemét when -2.4 oC temperature was measured in the morning. The temperature largely varied among sites. The trees protected the grapes in the traditional intercultural cultivation. The high trellises also gave protection to vines. The time of budbreak was also a crucial point. Seven grape varieties were examined in the vineyard that is located in Kecskemét-Máriahegy: Kadarka, Pirosszlanka, Kövidinka, Rajnai rizling, Narancsízű, Pannon frankos and Merlan. The Pontica varieties regenerated best. Narancsízű variety is a table grape variety that has a lower bud fertility. Between the two resistant varieties, the numbers of clusters were different. Rhine Riesling which has a late bud burst was less damaged by the frost.
