During 1987-90, nineteen strawberry cultivars and one selection from Agriculture Canada/McGill University were evaluated for their fruiting and other plant characteristics. Based upon an index of potential return which Integrates percent yield at each harvest date and total yield, the following cultivars listed in decreasing order of desirability (early productivity) are recommended: `Chambly', `Annapolis', `Honeoye', `Kent' and `Cavendish'. `Lina', `Lester', SJ83OR-2, `Bounty' and `Settler' have the most concentrated ripening period based upon an index of concentration. Highest yields were obtained with `Honeoye', SJ83OR-2, `Chambly', `Kent', Glooscap` and `Oka'. All had large, medium-firm fruit. Because of their tolerance to the herbicide terbacil and their large, medium-firm fruit, `Chambly', `Oka' and SJ830R-2 appear to be potential replacements for the commercial cultivars `Kent', `Honeoye' and `Glooscap' and are recommended for trials in Quebec. `Cornwallis', `Settler', `Midway', `Cavendish' and `Redcoat' had the lowest yield variability of the cultivars on trial.

Sixteen commercially grown strawberry cultivars with different degrees of resistance to red stele were evaluated for yield, plant characteristics and fruit quality. `Bounty', `Midway', and `Sparkle' had sufficient interior and exterior fruit color, good to satisfactory flavor and suitability for freezing. However, these cultivars as well as `Redcoat' lacked sufficient fruit firmness. `Bounty', `Redcoat', `Redchief and `Sparkle' had the highest yield in the three-year test. `Annapolis', `Earliglow' and `Scott' had reflexed calyx whereas `Allstar', `Annapolis', `Cornwallis', `Earllglow', `Guardian' and `Sunrise' were characterized by a raised neck suitable for mechanical dehulling. `Sunrise' appeared to be the only cultivar free of leaf scorch and leaf spot. `Tristar', `Redchief, `Lester', `Darrow' and `Arking' roots had the lowest incidence of red stele when planted in a naturally-infested field. No relationship between fruit characteristics was observed which suggests the necessity to examine each Individual tralt.
