Annapolis and Cornwallis are short-day, fresh market strawberry (Fragaria × ananassa Duch.) cultivars with resistance to red stele root rot caused by Phytophthora fragariae Hickman. Annapolis, which produces large fruit, is early ripening. Cornwallis, which ripens in the early to mid-season, may have some processing applications. Key words: Fragaria × ananassa, fruit breeding, Phytophthora fragariae

Glooscap and Blomidon are short-day strawberry (Fragaria × ananassa Duch.) cultivars which produce large fruit suited to the fresh market. Glooscap, which is particularly high yielding and winter hardy, ripens in midseason whereas Blomidon, which is particularly glossy and attractive, ripens mid- to late season. Key words: Fragaria × ananassa, fruit breeding, strawberry

Governor Simcoe and Secord are two June-bearing strawberries (Fragaria × ananassa Duch.) released as fresh market berries. Both have very large firm fruit with good flavor. Both ripen mid-late season with Secord ripening slightly earlier than Governor Simcoe.Key words: Fragaria × ananassa Duch., strawberry, fruit breeding, cultivar description

A bean (Phaseolus vulgaris) line, A - 300, resistant to Rhizoctonia solani and Fusarium oxysporum was introduced into Ontario from Colombia. The results of tests conducted in a root-rot nursery, in a greenhouse and in a growth room showed that this bean line is resistant to Fusarium solani f. sp. phaseoli and Pythium ultimum. Key words: Bean, Phaseolus vulgaris, root rot resistance

Ten species of Pythium and a group of isolates that produced filamentous sporangia but did not form sexual structures (Pythium ‘group F’) were recovered from the root systems of fresh market bell pepper plants grown on polyethylene-mulched production systems in Florida. Pathogenicity tests using pasteurized field soil inoculated with infested wheat seed demonstrated that P. aphanidermatum, P. myriotylum, P. helicoides, and P. splendens can cause significant root rot and reductions in root growth of pepper. P. aphanidermatum and P. myriotylum caused the most severe root rot, the greatest reductions in plant weight, and 42 and 62% plant mortality, respectively. In pathogenicity tests with tomato plants, these four species produced similar plant weight losses and disease ratings to those observed in pepper, but little or no plant mortality. Low incidences of root tip necrosis in pepper plants were observed with P. arrhenomanes, P. catenulatum, P. graminicola, and P. irregulare, but none of these species caused losses in root weight and only P. irregulare reduced shoot weight. P. periplocum, P. spinosum, and Pythium sp. F colonized root tissue of pepper but caused no significant root rot and did not adversely affect growth. Similar trends were observed with tomato, except that P. arrhenomanes caused limited root tip necrosis without affecting plant growth and P. catenulatum, P. graminicola, P. irregulare, P. spinosum, and Pythium sp. F colonized at least some of the plants but did not cause root disease. A significant interaction between temperature and P. aphanidermatum or P. myriotylum was observed on pepper transplants. The greatest reductions in growth occurred at 28°C, whereas plant mortality only occurred at 34°C.

When acclimated strawberry plants (Fragaria × ananassa Duch. ’Redcoat’) from the field were placed in a programmable freezer, mother strawberry crowns were as hardy or hardier than daughter crowns when frozen to −11 °C. However, under field conditions, daughter plants expressed consistently greater hardiness than mother plants. Mulching had no effect on daughter plant survival, whereas enhanced mother plant survival was observed. Field-growth habit of mother crowns may be the important factor for consistent winter survival under prairie conditions. A simple scoring system was developed to predict survival of strawberry plants. Key words. Fragaria × ananassa Duch., strawberry, crowns, low temperature hardiness

AC Hercule is a 2600 crop heat unit soybean (Glycine max [L.] Merr.) cultivar with seed protein levels about 3–4% higher than oilseed cultivars. AC Hercule is intended for whole-seed use in livestock rations. AC Hercule has field tolerance to phytophthora root rot. Key words: Soybean, cultivar description, high protein cultivar
