Ethnobotany of the crab apple tree (Malus sylvestris (L.) Mill., Rosaceae) in Spain

This study focuses on the morphological and genetic characteristics of European crab apple (Malus sylvestris (L.) Mill.) and the occurrence of hybrids in its populations. We analyzed a total of 107 putative European crab apple trees in Slovenia: 92 from nine natural populations, five from a seed stand and 10 from a stand of unnatural origin. We also included 18 domesticated apple trees (Malus × domestica Borkh.) and two Japanese flowering crab apple trees (Malusfloribunda van Houtte) as outliers. The trees were classified into groups of European crab apples, hybrids and domesticated apples according to their morphological and genetic characteristics. Classification based on morphological traits produced different results (58.75% European crab apple, 37.11% hybrids and 4.14% domesticated apple) compared to those based on genetic analysis (70.10% European crab apple, 21.64% hybrids and 8.26% domesticated apple). When genetic and morphological characteristics were combined, only 40.20% of the trees were classified as European crab apple, and an additional group of feral cultivars of domesticated apples (6.18%) was identified. The analysis revealed that hybridization with domesticated apple is taking place in all studied natural European crab apple populations; however, hybrids and feral cultivars only occur to a limited extent. When introducing European crab apple into forests in the future, only genetically verified forest reproductive material obtained exclusively from suitable seed stands should be used.

Javid is a winter-hardy, scab-resistant ornamental apple tree released by Agriculture and Agri-Food Canada (AAFC), Horticulture Research and Development Centre (HRDC). It is suitable for growing in Quebec and eastern and central Canada. The name ‘Javid’ is derived from the Persian ‘jawid’ meaning eternal, forever, continuous or permanent, due to its fruit persistency after ripening, and is named after the first author's son.

The results of studying the collection of North American apple-tree species are presented. Forms with a whole set of traits interesting for breeding are highlighted, including such features as late flowering schedule, disease resistance, long shelf life of fruits, etc. In addition, the small-fruited ornamental apple-tree (crab apple) accessions obtained from North American species are briefly described, and the most valuable of them are recommended for practical uses.

Abstract A description is provided for Gymnosporangium juniperi-virginianae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Aecia on apple (Malus sylvestris) and crab apple (Malus sp.). Telia on Juniperus virginiana and related species of the 'sabina' group. DISEASE: American apple rust. Aecia chiefly on the leaves but also on stems and fruit. Telia on globoid or kidney-shaped galls of juniper. GEOGRAPHICAL DISTRIBUTION: Widespread in the USA east of the Rockies, also in California, Ontario and Quebec (CMI Map 61, ed. 2, 1965).
