“…As detailed inheritance analyses have not been carried out in S. torminalis, genetic control and the mode of inheritance of isozymes was inferred from other deciduous tree species, e.g. Sorbus aucuparia (RASPÉ et al, 1998) and Pyrus communis (CHEVREAU et al, 1997). Additionally, for better interpretation of obtained zymograms, open-pollinated progeny of three trees with known genotypes was analysed.…”

Genetic Variability and Structure of The Wild Service Tree (Sorbus torminalis (L.) Crantz) in Poland

Sorbus torminalis is a rare forest tree species in Poland. Allelic and genotypic structures at 25 isozyme gene loci were observed in 20 populations from Poland, situated mainly along a latitudinal gradient. Levels of genetic diversity were high both at the species level (P = 44 %, H e = 0.435) and within populations (mean P = 40.8 %, mean H e = 0.373). Levels of differentiation among populations were relatively high (F ST = 0.17) and a noticeable geographic structure of this differentiation was detected. The population in the 'Brekinia' reserve had a unique genetic structure of a clonal population and was the most distinct from the other populations.

Identification of Asian Pear Varieties by SSR Analysis

et al. 2002

Sixty Asian pear accessions from 6 Pyrus species were genetically identified by 9 SSR markers with a total of 133 putative alleles. Among them, 58 varieties could be successfully differentiated except for 2 pairs of synonymous or clonal varieties. All the SSR markers produced 1 or 2 discrete amplified fragments for all the diploid accessions, whereas a triploid variety showed 3 fragments with some SSRs. The number of putative alleles ranged from 7 to 20, with an average value of 14.8. The observed heterozygosity and the power of discrimination were 0.63 and 0.91, respectively. A phenogram based on the SSR genotypes was obtained, showing 3 major groups corresponding to the Japanese, Chinese and European groups. The SSR markers were highly polymorphic and could be utilized as a reliable tool for cultivar identification in Asian pears.
