Evaluation of Pear (Pyrus communis L.) Germ plasm Collected in Bosnia and Herzegovina Using Some Pomological and Ecophysiological Characteristics

摘要

33 pear (Pyrus communis L.) accessions originating from the five most important fruit BiH regions were collected in ex situ collection and evaluated during a three-year long research. Evaluation of pomological and biochemical fruit analyses as well asof ecophysiological characteristics has been conducted. The experimental data were biometrically processed by arithmetic mean with related measures of variability, t-test and cluster analysis. Analyzed pear accessions ripen from early July to early October and were appropriate for the local market. Half of them ripen before and half after the cultivar 'Williams'. The total content of soluble solids in fruit flesh was on the average level of commercial genotypes. According to the firmness of the fruit flesh most genotypes do not manifest predisposition for longer storage and transport. Some accessions have full predisposition to parthenocarpy and others have more than 80% mature embryos. Demonstrated differences in the dynamics of flowering must be taken into account in their expansion, i.e., the introduction in plantation cultivation and selection of genotypes as pollinators. Most of the analyzed accessions can be an important source of germplasm for breeding because of stable characteristics.
