red clover/phenotypic correlations/productivity elements/ diploid and tetraploid cultivars
Abstract
Studying the correlations between productivity elements of red clover (green matter, dry matter and seed yield) is a very important aspect of breeding programs because it helps obtaining highly productive cultivars. Positive correlations, statistically assured, were observed between green and dry matter yields in both years of
vegetation, for both groups of ploidy. Negative correlations were noticed between seed yield and first cut green matter yield in the 2nd year, for diploids and between seed yield and total green and dry matter in the 1st year, for tetraploids.
