Abstract
The production of sweet corn has been increased recently. It is a very delicious vegetable species with wide variety assortment. Nowadays, new varieties which come to markets are characterized by improved properties, higher sugar content and their stability in storage. Thus, it is necessary to know basic variety parameters for better orientation in wide corn assortment. According to earliness, sweet corn varieties were classified to following groups: very early or early (RISING SUN F1; 874 F1; SF 1073 F1; SF 583 F1); middle-late (SF 681 F1; 1027 F1; ASTRONAUT F1); late (GALAXY F1; SPACE SHIP F1) and very late (MATADOR F1). The day number from tassel anthesis to harvest is an important parameter of sweet corn for potential grower and its lowest value was found at variety RISING SUN F1. On the basis of gained results, we classified all evaluated varieties to the group of super-sweet corn (sh-2) with slow decline of sugar content and storage possibility in cold conditions from 4 to 7 days after harvest. The sugar content of sweet corn is a parameter having important role for purchase by consumers. The variety had statistically significant impact to the sugar content and its highest value was determined at variety 874 F1.
