NOVÁ ODRŮDA TŘEŠNĚ ‘HL 16732’ A JEJÍ FENOTYPOVÁ A MOLEKULÁRNĚ GENETICKÁ CHARAKTERIZACE [NEW SWEET CHERRY CULTIVAR ‘HL 16732’ AND AND ITS PHENOTYPIC AND MOLECULAR GENETIC CHARACTERIZATION]

Abstract

‘HL 16732’ is a newly registered cultivar of sweet cherry (Prunus avium L.) with a blush fruit colour, which can become very attractive for producers, processors and consumers. In addition to the classical evaluation of the phenotype, this genotype was also verified by molecular methods, which determined its pollination ratios, verified the origin and the allelic composition of molecular markers associated with the key breeding characteristics of this cultivar: fruit colour, harvest time, fruit weight and fruit firmness. The results showed many advantages of the cultivar ‘HL 16732’, including later flowering, high flower and fruit set, moderately high productivity and consistent ripening. Molecular analyses confirmed its uniqueness and the excellent properties of the cultivar, which is also suitable as a starting material for further breeding. This cultivar thus has the potential to become an important choice for producers and the blush cherry market.
