Bruce birdsfoot trefoil (Lotus corniculatus L.) is a 71-clone synthetic variety developed at the Nappan Research Farm, Agriculture and Agri-Food Canada, Nappan, Nova Scotia. Bruce was developed through two cycles of mass selection for plant vigour (top and root growth) and winterhardiness, and one cycle of mass selection for re-growth vigour under grazing. In Atlantic Canada, Bruce produced more forage than the check cultivar Leo during 3 post-seeding years. It was also superior in spring growth with high first-cut herbage yields.

AC Langille is a birdsfoot trefoil (Lotus corniculatus L.) cultivar developed by the Nappan Research Farm, Agriculture and Agri-Food Canada. It was developed through two cycles of mass selection for winterhardiness and one cycle of mass selection for seedling vigor. The original material was six distinct germplasms selected from the cultivar Leo and released from the Crop Science Department of the University of Guelph. AC Langille is superior to the check cultivar Leo in forage yield and seedling vigor in Atlantic Canada. Key words: Birdsfoot trefoil, Lotus corniculatus, cultivar description, seedling vigor

Forage Yields

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.

AC Nordic is a late-maturing orchardgrass (Dactylis glomerata L.) cultivar. It was developed by mass selection for yield, persistence and resistance to stem rust (Puccinia graminis) at the Plant Research Centre, Agriculture Canada, Ottawa. Its yield was similar to that of cv. Sumas in a total of 33 station years in Quebec. Yield in second and subsequent production years was 101.6% of cv. Sumas over 19 station years.

Seed Yields

Birdsfoot trefoil (Lotus corniculatus L.), cult Leo, was used as a base population for a recurrent selection program for seed yield. Objectives were: (1) improvement of seed yield, and (2) comparison of a genotypic and a geno-phenotypic method of selection. Two cycles were completed and evaluated. Seed yields for the genotypic and geno-phenotypic methods were 132 and 158%, respectively, of Leo after two cycles of selection. The geno-phenotypic method proved superior to the genotypic after each cycle. The broad sense heritability (61% for cycles 1 and 2), genotypic standard deviation, and genotypic coefficient of variability estimates (16.9 and 15.0% for cycles 1 and 2) indicated no reduction in genotypic variability with the geno-phenotypic method. However, the variability was practically exhausted with the genotypic method after cycle 2. Thus, further improvement with additional cycles of selection should be possible with the geno-phenotypic method but not with the genotypic method.

A chemical analysis of the polyphenolic patterns of diploid and tetraploid populations of Lotus corniculatus s.l. (Fabaceae) growing in the southern French Alps showed that diploids from Mont Ventoux and from Montagne de Lure belong to the same chemotype. On the other hand, tetraploids showed two different chemotypes. This paper suggests the following hypothesis about the evolution of Lotus corniculatus in this area since the last glaciation: diploids could be derived from a relic diploid population scattered by glaciation and restricted within very narrow areas, whereas the tetraploids originating from the diiploids were more competitive and radiated into larger areas cleared from ice.
