Comparison of Czechoslovak and Romanian varieties of red clover (Trifolium pratense L.)

Abstract

Twenty-eight varieties of red clover (Trifolium pratense L.) - among them three Romanian varieties - were tested under different conditions at three stations of the Research and Breeding Institute for Fodder Plants (1980-1982). Results of the first harvest year (1981), Czechoslovak varieties and new breeding were compared with Romanian varieties: in total yields of green fodder from three stations the variety Napoca Tetra was the best. The variety was characterized by large leaf area, typical for Romanian diploid varieties as well. From the viewpoints of quality, crude protein and fiber content the Romanian varieties were among the best. Rate of infection by viruses was the lowest in the tetraploid varieties (among them in Napoca Tetra); the diploid varieties suffered from virus diseases to a greater extent.
