Abstract
‘Festivee’ (Fig. 1) is a reddish black, large berried, good quality, seeded table grape with a breaking meaty flesh. It matures 1 week before ‘Concord’.
Abstract
‘Veeblanc’ (Fig. 1) is a white wine grape that produces a well balanced, dry, white table wine.
Abstract
‘Ventura’ is a white wine grape (Fig. 1) which has received favorable performance reports from tests in Ohio, Michigan, New York and Ontario. It was released in February 1975.
Abstract
The responses of ‘Concord’ grape vines (Vitis labrusca L.) to 3 potassium fertilizer sources (KCl, K2SO4, and KNO3) used at 2 rates were compared. Fertilizers were applied for 10 years to vines on a poorly drained Jeddo clay loam soil. Performance on a moderately well-drained Oneida clay loam as influenced by KCl and K2SO4 levels was also studied. There was no reduction in yield, fruit quality, or vine vigor with high rates of KCl. KCl and K2SO4 were equally effective in increasing petiole K but the response was slow under Jeddo clay loam conditions. Yield, vigor, and petiole K levels were less with vines receiving KNO3 than with those receiving other sources of K, or with the non-treated control vines. KNO3 was undesirable as a source of K. Petiole K was higher in grape vines growing on Onedia clay loam than on Jeddo clay loam; in addition, they responded more quickly to applied K irrespective of source. There was an indication of a yield response one year to high levels of KCl but no such response occurred with K2SO4. No toxic response to high rates of KCl was detected at either location.
Abstract
‘Vivagold’ is an attractive, medium-sized apricot (Prunus arnieniaca L.) ripening a week after ‘Veecot’. It is moderately resistant to brown rot (Monilinia fructicola (Wint.) Honey). It has shown some bacterial spot (Xanthomonas pruni (E. F. Smith) Dowson) occasionally but not so severe as has ‘Veecot’. It was introduced in 1978 to extend the season of attractive good quality apricots.
Abstract
‘Velvaglo’ is a very attractive apricot (Prunus armeniaca L.) ripening in the last week of July with ‘Goldcot’. It has moderate resistance to bacterial spot (Xanthomonas pruni (E. F. Smith) Dowson), brown rot (Monilinia fructi-cola (Wint.) Honey) and perennial canker (Leucostoma spp). It was introduced in 1978 as a later-ripening cultivar than ‘Harcot’, adapted to conditions of southern Ontario, Canada.
Abstract
Grape breeding was initiated at the Horticultural Research Institute of Ontario in 1913 (3). The objectives of the breeding program were to provide wine and table grapes adapted to Ontario growing conditions. ‘Vanessa’ (Fig. 1) was released by the Horticultural Research Institute of Ontario to fill the need for seedless table grapes hardy enough to withstand winter conditions in southern Ontario. This is the seventh cultivar released from this program.
Abstract
Grape breeding was initiated at the Horticultural Research Institute of Ontario in 1913 (3). The objectives of the program were to provide wine and table grapes adapted to southern Ontario climatic conditions. ‘Vivant’ (Fig. 1) was released by the Horticultural Research Institute of Ontario to help fill the need for hybrid grape cultivars with vinifera-like character for the active white wine market. This is the 8th cultivar to be released from this program.
Abstract
‘Veeglo’ is an attractive, high quality peach (Prunus persica (L.) Batsch) that matures during the last week in August, 9 days after ‘Redhaven’. Assessments indicate typical, moderate susceptibility to perennial canker (Leucostoma spp.) and moderate resistance to bacterial spot (Xanthomonas pruni (E.F. Smith) Dows.). ‘Veeglo’ was introduced to satisfy the requirement for a high quality fresh market or home preserving peach maturing between Redhaven and Loring, and adapted to climatic conditions in southern Ontario, Canada.
Abstract
Five grape cultivars (Vitis spp.) varying in vine vigor were planted at 4 spacings (1.8 m × 1.8 m, 1.8 m × 2.7 m, 2.7 m × 1.8 m, 2.7 m × 2.7 m) on a Trafalgar silty clay loam soil in Ontario. In each of the first 5 harvest years (years 3 through 7 following planting), lowest yields per vine were obtained from the closest spacing (1.8 m × 1.8 m) but the increased plant number at this spacing resulted in highest yields/ha. Fruit quality, as evidenced by soluble solids and titratable acidity, was not adversely affected by close spacing. There was a greater reduction in fruit yields per vine and vegetative growth at the closer within-row spacing than at the closer between-row spacing; this effect of within-row competition was especially pronounced for the vigorous cultivars. Results obtained in this study indicate that increasing the planting density (by reducing the between-row distance) of grapevines on clay loam soils in Ontario may lead to economical increases in production.
