Comparison of Old and Landraces Varieties of the Apple Tree (Malus domestica Borkh) in the Variability of Some Morphological Characters of Leaves and Flowers

Abstract

Old and landraces varieties of cultivated plant species selected from natural populations adapted to long-term cultivation, which represent a rich genetic potential for the development of agroecosystems and agriculture under specific conditions, resources for an environment aestheticization, landscaping and development of cultural traditions. The research focused on determining the economic value of a selected collection of old and landraces varieties and fruit-bearing seedlings of apple tree (Malus domestica Borkh), widespread in Slovakia for their practical use in organic farming or as genetic resources for breeding new varieties for organic food production. For experimental evaluation, we used 73 old and landraces varieties of apple trees concentrated and preserved ex-situ in a clone repository in the village Bacúch and 77 fruit-bearing seedlings, which originated from free pollination and grown in-situ form around Nitra,

Comparison of Old and Local Apple Varieties and Seedlings (Malus domestica Borkh.) in the Variability of Some Morphological Characters of Fruits and Seeds

“…Evaluation and identification of genotypes based on morphological traits are important for the detection and selection of individuals that are suitable genetic material for hybridization and breeding program of new varieties, which contributes to the global conservation of biological diversity (Monka et al, 2014;Grygorieva et al, 2017aGrygorieva et al, ,b, 2018aMotyleva et al, 2017Motyleva et al, , 2018Ivanišová et al, 2017;Vinogradova et al, 2017;Brindza et al, 2018Brindza et al, , 2019Fatrcová-Šramková et al, 2019;Horčinová Sedláčková et al, 2020).…”

Influence of Variety on Total Polyphenols Content and Antioxidant Activity in Apple Fruits (Malus domestica Borkh.)

“…Apples (Malus domestica Borkh.) are widely cultivated throughout the world for their well-known nutrition and refreshing taste (Moscetti et al, 2018), and they are a highly researched crop within the scientific community (Havryliuk and Kondratenko, 2019;Horčinová Sedláčková et al, 2020;Horčinová Sedláčková et al, 2021). These fruits are not consumed just fresh; approximately one-third of them are processed into various goods, from which beverages belong to the most popular (Candrawinata et al, 2012).…”
