The contents of four isoflavones: daidzein, genistein, formononetin and biochanin A were analysed in breeding stocks of red clover with the purpose to find stocks with the highest and lowest levels of these compounds. The total content of the isoflavones in twenty nine stocks studied, varied within the range of 0.70 to 1.19% D.M.

Preliminary investigations were carried out in order to ascertain the occurrence of isoflavonoid compounds characterized by estrogenic activity, in five domestic species of clover: Trifolium pratense L., T. repens L., T. incurnatum L., T. resupinatum L. and T. hybridum L. Large amounts of biochanin A (0.8% d.m.) and formononetin (0.7% d.m.) and small amounts of genistein were identified in the green parts of red clover. In the remaining species, small amounts of formononetin and genistein were found. In all the species of clover, free isoflavonoid aglycones and glycosides were found. Laboratory tests carried out on mice showed that only T. pratense contained high estrogen activity. Red clover also had an unidentified factor which inhibited the increase of the body weight of young mice.

Influence of the harvest term of red clover on content of five isoflavones in leaves was examined in microfields experiment. It was found that the content of these compounds in leaves of red clover collected in flowering stage was the same as in clover collected in the budding stage, in the first cut. In the second cut the isoflavone content was determined by phase of plant development. The level of formononetin, biochanin A and pratensein in the second cut was higher than in the first cut, but the content of daidzein and genistein was lower. The cutting date of the first cut can influence on the isoflavone content at the second cut. Tetraploid varieties acumulated more isoflavones than diploid varieties.

The concent of formononetin, the predominant estrogen, was analysed in four cultivars of red clover. Its highest content was found in cv. Jubilatka (tetraploid) - 0,57 % DM, next, in cv. Hruszowska (diploid) - 0,44%, Radyka (tetraploid) - 0,39 % and Skrzeszowicka (diploid) - 0,3 %. High variation from plant to plant was found in all of the analysed cultivars, which makes it possible to select for a low formononetin clover population. The content of formononetin in individual plants in two consecutive years was positevely correlated. The content of biochemin A in two cultivars was also analysed employing a semi-quantitative TCL test. It was found that the concent of these two estrogens in individual plants was positively correlated. However, some individual plants containing high ammount of only one estrogen were also found. Because of that in the selection for low-estrogen red clover, after selection of low formononetin plants, an additional test for biochanin A is recomended.
