Abstract
Four traits found in red clover (Trifollum pratense L.) were each determined to be controlled by single, recessive genes in the homozygous state. Three morphological traits, split leaflet, round pollen, and purplered flower color, should serve as useful genetic markers. The remaining gene affects melosis, and results in univalents at diakinesis and the subsequent formation of 2n eggs. This has been useful in producing tetraploid red clover. The symbols sl, rp, and sy, have been proposed to designate, respectively, genes for split leaflet, round pollen, and synaptic mutant. As the purplered flower color may be a rediscovery of an earlier gene, p, this symbol has been maintained to designate purple-red flower color.
