Abstract

‘Harrold Red Delicious’, ‘Golden Delicious’, ‘Spartan’, ‘McIntosh’, ‘Tydeman's Red’ and ‘Quinte’ apples were compared over a 12-year period on Mailing (M) 9, M 26 and M 7 rootstocks on variable soil at Summerland. ‘Harrold Red Delicious’ performed well on M 7, poorly on M 26 and M 9. ‘Golden Delicious’ was precocious and productive on all rootstocks, with fairly uniform performance on M 7 and M 26, but was extremely variable on M 9. ‘Spartan’ trees were precocious, productive and uniform on M 7, but variable on M 26 and of poor habit on M 9. ‘McIntosh’ performed best on M 7, being variable on M 26 and M 9. ‘Tydeman's Red’ and ‘Quinte’ lacked precocity and productivity on all 3 rootstocks.

Abstract

‘Swiss Bartlett’ pear (Pyrus communis L.) was evaluated on Old Home × Farmingdale (OH × F) rootstocks 34, 69, 87, 130, 230, 333, and 515; EM Quince A and LePage C Quince, and Old Home and Bartlett seedlings planted in 1974 at 2.4 × 4.8 m. All trees on OH × F 51 were winter-killed within 2 years of planting and thus could not be evaluated. Marketable yields from 1975 to 1979 inclusive showed OH × F 87 to be the most precocious rootstock, followed by OH × F 515, 34, and 69. Yields from 1975 to 1984 inclusive were highest for OH × F 87, 515, 34, and 69, but were not significantly different from each other. Tree size, as indicated by trunk cross-sectional area, was largest for OH × F 515 and 34, followed by OH × F 87 and 69. Tree efficiency values as recorded for the trees in their 5th and 10th year of production were higher for OH × F 87, OH × F 69, EM Quince A, and Lepage Quince C than for most of the other rootstocks.

Abstract

A consistent desire for a uniquely flavored seedless table grape has prompted the release of ‘Simone’. Unlike its sister seedling ‘Sovereign Coronation’ (Denby, 1977), ‘Simone’ possesses a very mild labruscana flavor character. It is a blue, seedless, midseason table grape that matures at Summerland in late September.

Abstract

‘Sovereign Tiara’ (Vitis spp. hybrid) is the second of two white wine grape cultivars recently released by the Agriculture Canada Research Station, Summerland, B.C. Like ‘Sovereign Opal’ (1), ‘Sovereign Tiara’ is a late-midseason grape cultivar useful for both varietally labeled and proprietary products. Consistently high yields make ‘Sovereign Tiara’ ideal for use as a bulk blending grape, and render it advantageous over ‘Sovereign Opal’ for this purpose. Compared to ‘Okan-agan Riesling’, yield and winter hardiness of ‘Sovereign Tiara’ are superior, while fruit composition is comparable.
