Processing Evaluation of High-Bush Blueberry Varieties in Ontario

The aroma of some hybrids between high-bush blueberry (Vaccinium corymbosum, L.) and Bog Blueberry (Vaccinium uliginosum, L.)

The most important volatile components of some cultivated high-bush blueberry varieties and of bog blueberry, together with those of seven hybrids between high-bush blueberry (Vaccinium corymbosum, L.) and, bog blueberry (Vaccinium uliginosum, L.), were studied by a mass-fragmentographic SIM (Selective Ion Monitoring) technique.

Blueberry Varieties for Florida

Blueberries are native to eastern North America. They are one of the few crop plants that originated here. The rabbiteye blueberry (Vaccinium ashei) occurs mostly in certain river valleys in northern Florida and southeastern Georgia. The highbush blueberry (Vaccinium corymbosum) is native in the eastern third of the United States and southeastern Canada. Florida is rich in other native Vaccinium species. The woods and swamps of Florida are populated with at least eight wild blueberry species. No area of the state lacks wild blueberries, except where soil pH is above 6.0.

The propagation of highbush blueberries by softwood cuttings

Rooting trials with softwood cuttings of several highbush blueberry varieties were carried out in 1964 and 1965. It appeared that considerably better results can be obtained with late-spring cuttings than with summer cuttings commonly used up till now.

Cytological observations on some species and hybrids ofVaccinium

Meiosis was studied inVaccinium myrtillus (n=12),V. vitis-idaea (n=12),V. myrtillus ×vitisidaea (n=12), colchicine-induced tetraploidV. myrtillus (n=24),V. uliginosum (n=24), the cultivated blueberry varieties ‘Rancocas’ and ‘Pemberton’ (n=24), and the hybridsV. uliginosum × ‘Rancocas’ andV. uliginosum × ‘Pemberton’ (n=24). Pairing was regular in the diploid species. Some multivalent formations occurred inV. uliginosum and in the cultivated blueberry varieties and to a considerable extent in the autotetraploidV. myrtillus. The spontaneous diploid hybridV. myrtillus ×vitis-idaea displayed numerous meiotic irregularities, whereas the artificial hybrids betweenV. uliginosum and cultivated blueberry showed relatively regular meiosis. Pairing relationships of the various genomes are discussed. Breeding programs for the use of North-European species with American cultivated blueberry varieties are discussed in the light of the cytological observations.

These observations have been made with a view to examining the horticultural value of ten highbush blueberry varieties of American origin under Finnish conditions. The varieties are as follows; Atlantic, Burlington, Concord, Jersey, June, Pemberton, Rancocas, Rubel, Scammell and Stanley. The material originates from two nurseries in the United States. The bushes have been planted in spring 1947 as one-year-olds. They have yielded during the summers of 1948 and 1949. The observations are thus preliminary in character and are, indeed, insufficient for a final decision on the suitability of the different varieties to Finnish conditions. The results of the observations are presented in Tables 1—7 and in Graph. 1. The results presented in the tables concern the following subjects: the rate of growth, the number of yield-aged bushes, the amount of the yield, the earliness of ripening, the average weight of one berry, the decrease of the size of the berries harvested at the end of the yielding season, and the desert quality of the berries. When possible, comparisons have been made with the results obtained from American experiments. On the basis of the various observations the conclusion has been drawn that Rancocas. Pemberton, Stanley and June seem to be the most promising varieties for continued experiments under Finnish conditions. It has been established that several characters of some of the varieties tested deviate considerably from that observed earlier in the United States. Atlantic has proved to be one of the earliest varieties in Finland. In addition the size of the berries is smaller than in America. Pemberton is here not a late but a midseason variety. The variety Rancocas has produced berries considerably larger than under American conditions.
