The studies performed at the Research Institute for Fodder Plants, Troubsko, have concerned zigzag clover (Trifolium medium) since 1981. From the five original ecotypes coming from different locations of Czechoslovakia, the material, obtained by recurrent selection, was used for the establishment of a half-sib progeny nursery, progeny tests and for a polycross test. Growth and development characteristics, forage yield, including chemical composition, and seed yield in relation to morphological characters (rhizome formation, stem number, stem length and thickness, leaf proportion, leaf area, number of heads/plant, number of flowers/head, number of seeds per head) were the criteria of evaluation. It has good resistance to common clover virus diseases and average resistance to powdery mildew, which is better than in red clover. The objective of the studies was to develop a perennial clover with appropriate formation of shorter rhizomes and herbage yield which could be used as a constituent of persistent clover/grass stands.
