Studies of interspecific hybridization between perennial Trifolium species and Trifolium Pratense L.

Bastien, Denis Jean-Marie. January 1965 (has links)
Red clover has always occupied an important position anong the forage legumes grown in Canada and the United States. However, the acreage devoted to red clover (Trifolium pratense L.) has declined due to weaknesses in some important agronomic characteristics. A main weakness is its survival two or more winters. The winter survival of red clover depends, of course, on many different factors. Common objectives in breeding are (1) greater winter hardiness, (2) better disease resistance, and (3) a more perennial growth habit. [...]
