Kayak is a high yielding early maturing orchardgrass (Dactylis glomerata L.) cultivar with good level of winterhardiness suited for silage and hay production in western Canada including interior British Columbia. The population was developed at the Agriculture and Agri-Food Canada (AAFC) Research Centre, Lethbridge, AB. In BC and Western Forage Trials (WFTests), Kayak yielded 4% better than the check cultivar Kay under both rain fed and irrigated conditions. Kayak orchardgrass produces 10% more seed yield than Kay while its seed size is slightly smaller than Kay. Key words: Orchardgrass, Dactylis glomerata, high forage yield, winterhardy

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.

Chilliwack-VR is a medium-maturing orchardgrass (Dactylis glomerata L.) population with high levels of resistance to Cocksfoot Mottle Virus (CfMV) suited to silage and hay production in regions with a moderate temperate climate. The population was developed at the Pacific Agri-Food Research Centre (PARC), Agriculture and Agri-Food Canada (AAFC), Agassiz, BC, in collaboration with AAFC Research Centre, Lethbridge, AB. In BC trials, Chilliwack-VR yielded 5% more than the check cultivar Potomac without inoculation with CfMV and 23% better than the check when inoculated with the virus. In a southern Alberta trial, Chilliwack-VR survived for 3 yr and yielded as much biomass as a winterhardy check cultivar, Kay.

Effect Of Feeding

Alfalfa or orchardgrass hay was fed to cattle before feeding fresh alfalfa herbage at the vegetative to early bud stage of growth to observe the subsequent impact on bloat. Alfalfa hay supplements reduced the incidence of bloat by a third in one trial, but no effect was seen in a second trial. In contrast, supplements of orchardgrass hay reduced the occurrence of bloat by > 90% in 2 yr of trials. Supplemental orchardgrass hay can be effective in the control of pasture bloat.

Phleum Pratense L

Three cycles of recurrent restricted phenotypic selection for forage yield were carried out in orchardgrass (Dactylis glomerata L. 'Avon' and 'Pennlate') and timothy (Phleum pratense L. 'Salvo' and 'Drummond'). The objectives of this study were to measure the effectiveness of this selection and to assess whether the selection produced any correlated responses on other characters. The three selected cycles and the original populations (cycle 0) were evaluated in both sward and space-planted experiments over a period of 4 yr. For the majority of the years of evaluation, there were no significant (P < 0.05) differences in forage yield among the different selection cycles. Under space-planted evaluation, cycle 3 of Drummond timothy was lower in both forage and seed yield than the other populations. In general, there was a trend to taller plants with greater circumferences in orchardgrass, and shorter, smaller plants in timothy over selection cycles. Selection had little effect on plant persistence and maturity. In conclusion, three cycles of recurrent restricted phenotypic selection were not effective in improving the forage yield of timothy or orchardgrass.

Foxtail barley (Hordeum jubatum L.) is a troublesome weed in irrigated pastures. Several grass species seeded on two irrigated pastures at Lethbridge to test their ability to compete with foxtail barley. Tall fescue (Festuca arundinacea Schreb.) and creeping foxtail (Alopecurus arundinaceus Poir) reduced foxtail barley groundcover significantly compared to orchardgrass (Dactylis glomerata L.), pubescent wheatgrass (Agropyron trichophorum (Link) Richt.) and western wheatgrass (Agropyron smithii Rydb.); therefore, seeding of these grasses in areas subject to foxtail barley invasion should be encouraged.
