AC Caribou alfalfa (Medicago sativa L.) is a cultivar developed by the Agriculture Canada Research Station in Sainte-Foy. It is similar to Iroquois in maturity, rate of growth, and fall dormancy. It is highly resistant to bacterial wilt (caused by Clavibacter michiganensis subsp. insidiosus (McCulloch) Davis, Gillaspie, Vidaver & Harris), resistant to verticillium wilt (caused by Verticillium albo-atrum Reinke & Berth.), and moderately resistant to phytophthora root rot (caused by Phytophthora megasperma Dreschs. f. sp. medicaginis T. Kuan & D. C. Erwin). AC Caribou, an alfalfa with fine leafy stems, is well suited for production in Quebec and the Maritime Provinces where winter survival may be a problem.Key words: Alfalfa, Medicago sativa, cultivar description

AC Nordica alfalfa (Medicago sativa L.) was developed by the Agriculture Canada Research Station at Saskatoon, Saskatchewan. It is similar to Beaver alfalfa in having a broad crown and a tap root with many branches. AC Nordica is 1–2 d earlier in maturity than Beaver. It is shorter than Beaver at 10% bloom, is slightly slower in regrowth following harvest, and displays less spring vigor. However, it excels in winter hardiness, rating similar to Anik and Drylander alfalfa. AC Nordica is highly resistant to bacterial wilt (Clavibacter michiganense subsp. insidiosum [McCulloch] Davis, Gillaspie, Vidaver & Harris), and moderately resistant to snow mold (Coprinus psychromorbidus Redhead & Traquair). AC Nordica is intended as a special-purpose cultivar for the northern prairies, the Peace River area of Alberta, and other high snowfall areas where snow mold (winter crown rot) may occur and where extreme winter hardiness is required.

Alert is a high-yielding, semi-erect great northern common bean (Phaseolus vulgaris L.) cultivar. It was developed from a series of crosses at the Centro Internacional de Agricultura Tropical (CIAT), Cali, Colombia, on contract to the Agriculture and Agri-Food Canada (AAFC) Research Centre, Lethbridge, with cooperation from the AAFC Morden Research Station. Alert is well adapted to the eastern Canadian prairies, yielding significantly higher than the check cultivar, US1140, at 130% in the official Manitoba Dry Bean Co-operative Registration Trials. Alert is moderately resistant to white mold and resistant to races 1 and 15 of bean common mosaic virus (BCMV). It is susceptible to the alpha and alpha Brazil races of anthracnose, but resistant to the delta race.

Prairie Blue, a medium- late maturing oilseed flax (Linum usitatissimum L.), was released in 2003 by Agriculture and Agri-Food Canada, Morden Research Station, Morden, Manitoba. This cultivar has high oil content, high oil quality, small seed size, very good lodging resistance and high yield in all soil zones of the prairies. It is immune to current North American races of rust [Melampsora lini (Ehrenb.) Desmaz], and moderately resistant to wilt caused by Fusarium oxysporum Schlecht. f. sp. lini (Bolley) Snyder & Hansen.

Lack Of Control

Application of phosphonate was investigated as a means of controlling phytophthora root rot (Phytophthora megasperma f. sp. medicaginis) in lucerne (Medicago sativa). Foliar sprays of the chemical at rates of 2, 4 and 8 g/L did not improve the persistence or dry matter production of susceptible or resistant cultivars of lucerne, despite a small reduction in the degree of damage inflicted on lucerne plants by a severe epiphytotic of the disease. Regular monthly applications gave no better control than single applications at establishment or at the time of the development of an epiphytotic. It is concluded that phosphonate is not efficacious in controlling phytophthora root rot in lucerne and will not improve the performance of susceptible cultivars in high risk situations.

Island is a high-yielding, tall, partially upright pinto bean (Phaseolus vulgaris L.), with short vines and an average seed weight of 38.5 g 100 seeds-1. It was developed at the Agriculture and Agri-Food Canada (AAFC) Research Centre, Lethbridge, AB, in collaboration with the AAFC Research Station, Morden, MB. Island is well adapted to wide-row irrigated production of the Canadian prairies, with yields exceeding those of Othello, the check cultivar. Island is moderately susceptible, as is Othello, to race 73 of anthracnose [caused by Colletotrichum lindemuthianum (Sacc. & Magnus) Lams.-Scrib]; and is moderately resistant to white mould [caused by Sclerotinia sclerotiorum (Lib.) de Bary].

The causal organism of Phytophthora root rot of lucerne (Medicago sativa) in Queensland was identified as Phytophthora megasperma var. sojae and a brief description of the organism is included. The results of disease surveys show that Phytophthora root rot is widespread and causes serious losses in lucerne in south eastern Queensland. A collection of lucerne cultivars and strains was screened for resistance to P. megasperma var. sojae both in controlled environment chambers and in a naturally infested field site. The cultivar Lahontan and the experimental strains ESI, BDSI, ECRSI and Combined showed high levels of resistance in both situations.
