Diploid Cultivar

AC Christie red clover (Trifolium pratense L.) is a diploid cultivar of the double-cut type. It was developed by phenotypic selection at the Crop and Livestock Research Centre, Agriculture and Agri-Food Canada, Charlottetown, PEI. It is early flowering, very winterhardy and has no pubescence on the stems. In Atlantic Canada it has produced more forage than the check cultivars in the second and third harvest years.

Azur is a diploid cultivar of red clover [Trifolium pratense (L.)], which was selected for vigor and growth habit in the year of seeding. In forage trials conducted in Québec, Azur was superior in dry matter yield to check cultivars, particularly in trials harvested in the second production year. In trials in Ontario and the Atlantic provinces, Azur was numerically superior in dry matter yield to the check cultivar, but not significantly so (P < 0.05).

The red clover (Trifolium pratense L.) cultivar, AC Charlie, is a diploid of the early or double-cut type. It was developed by two cycles of mass selection for persistence and vigour. Forage yields after severe winter conditions indicate that AC Charlie is more winterhardy than Florex in Atlantic Canada. It is similar in maturity to Florex and 3–4 d later than Marino.

Physiographic Regions

Red clover (Trifolium pratense L.) is one of the most important temperate legume species, used to lessen the lack of forage during the critical fall-winter period in Rio Grande do Sul, RS, Brazil. However, its utilization has been restricted mainly because of its lack of persistence. This work evaluates the dry matter yield and persistence of red clover half-sib progenies in two physiographic regions of RS: "Depressão Central", in Eldorado do Sul and "Encosta Superior do Nordeste", in Veranópolis. Experiments were carried out for two growing seasons and results were compared to two red clover commercial checks, Qüiñequeli and Estanzuela 116. The region of Veranópolis was more adequate for red clover forage production, enabling better yield and persistence. The best check for both locations was cultivar Estanzuela 116. At Eldorado do Sul persistence was highly affected and some progenies were superior to the best check. At Veranópolis the best check was very productive, with good persistence. The best progenies at both locations were selected to be propagated and submitted to additional recurrent selection cycles.

Cultivar Description

Tapani is a 21-clone diploid synthetic cultivar of red clover (Trifolium pratense L.). It was developed by phenotypic selection at Agriculture and Agri-Food Canada, Crops and Livestock Research Centre, in Charlottetown, Prince Edward Island, and at the Soils and Crops Research and Development Centre in Quebec City, Quebec. The original material for this strain was selected from collections made in old stands of red clover in three Atlantic Provinces of Canada. Tapani is early flowering and winterhardy. In Atlantic Canada, Tapani yielded an average of 109% of the check cultivar Marino over three production years. This cultivar has superior re-growth potential with high second-cut herbage yield.

Overall Resistance

In Wisconsin, Fusarium oxysporum, Schlect., a pathogen causing vascular wilt, is the most prevalent fungal pathogen recovered from diseased red clover (Trifolium pratense L.) plants. This study was conducted to determine the mode of inheritance for red clover resistance to this pathogen and to develop resistant germplasm. Virulent isolates of this pathogen, collected from red clover plants at the Ashland Research Station, Ashland, Wisconsin, were used to screen three populations, the red clover cultivars Arlington and Marathon and the C11 germplasm, for resistant plants. Plants were inoculated with the pathogen and evaluated for reaction, using a disease-severity index (DSI) score from 1 to 5 (1 = no reaction, 5 = plant dead). Selected plants from each cycle were intercrossed to produce subsequent generations. After two and three cycles of selection, the developed populations were simultaneously evaluated for gain from selection. The gain from selection for resistance in these populations (cycle 0 minus cycle 2) ranged from 0.31 to 0.48, 0.12 to 0.75, and 0.13 to 0.83 DSI units, respectively, for Arlington, Marathon, and C11. Estimated narrow-sense heritabilities, based on cycle-1 and cycle-2 progeny, were, respectively, 0.20 and 0.37 for Arlington, 0.15 and 0.13 for Marathon, and 0.06 and 0.17 for C11. These results indicate that resistance is a quantitative trait controlled by many loci, each contributing some portion to overall resistance in the host.

Seed Increase

Bytown is a tetraploid cultivar of Trifolium pratense L., developed at the Agriculture Canada Research Station, Ottawa, Ontario. The cultivar has larger leaves, stems and floral parts than its parent Ottawa diploid variety. It has shown greater persistence in Northern areas of Ontario and Quebec and will be used in dairy production as haylage. The SeCan Association will be responsible for seed increase and distribution. It was licensed in March 1979 and pedigree seed will be available to farmers in the spring of 1981.

Selection For

To increase the persistence of red clover (Trifolium pratense L.), phenotypic recurrent selection was conducted under field conditions. After three cycles of selection, a strain designated as CRS-16, was developed. This strain has better persistence than the check cultivars, Florex and Marino, and has a more fibrous root system. Among 4-yr-old plants, about 10% initiated new shoots from below the crown. Key words: Red clover, Trifolium pratense L. persistence, root type
