Raspberry (Rubus idaeus L.) cultivars are propagated vegetatively, as many other fruit species from the Rosaceae family. During propagation, mistaken identities of cultivars can be caused by mislabelling plants for various reasons. This poses a problem not only for growers who buy cultivars because of specific characteristics (e.g., resistance) but also for breeders who are being deprived of licensing fees for cultivars under Plant Variety Protection (PVP). In this study, six raspberry cultivars of up to six different origins were tested for trueness-to-type by fingerprinting with 16 SSR markers. Nine out of 33 samples turned out not to be true-to-type, seven from online shops and two from nurseries.

Raspberry (Rubus idaeus L.) is an important fruit crop (Graham et al., 2004) and cultivated in most areas in the world (Strik, 2007). Raspberry fruits are grown for fresh fruit market or commercial processing including products like juice, dried or frozen fruit and puree and its leaves are known for an astringent flavour in herbal teas (Hanke & Flachowsky, 2017). The main producing world re

Black and red raspberries (Rubus occidentalis L. and Rubus idaeus L.) are the prominent members of the genus Rubus (Rosaceae family). Breeding programs coupled with the low costs of high-throughput sequencing have led to a reservoir of data that have improved our understanding of various characteristics of Rubus and facilitated the mapping of different traits. Gene B controls the waxy bloom, a clearly visible epicuticular wax on canes. The potential effects of this trait on resistance/susceptibility to cane diseases in conjunction with other morphological factors are not fully studied. Previous studies suggested that gene H, which controls cane pubescence, is closely associated with gene B. Here, we used tunable genotyping-by-sequencing technology to identify the de novo SNPs of R. occidentalis and R. idaeus using an interspecific population that segregates for the waxy bloom phenotype. We created linkage maps of both species and mapped the identified SNPs to the seven chromosomes (Ro01–Ro07) of Rubus. Importantly, we report, for the first time, the mapping of gene B to chromosome 2 of R. occidentalis using a genetic map consisting of 443 markers spanning 479.76 cM. We observed the poor transferability of R. idaeus SSRs to R. occidentalis and discrepancies in their previously reported chromosome locations.

A comprehensive lexicon is a necessary communication tool between the panel leader and panelists to describe each sensory stimulus potentially evoked by a product. In the current scientific breeding and trading scenario, a multilingual sensory lexicon is necessary to ensure the consistency of sensory evaluations when tests are conducted across countries and/or with international panelists. This study aimed to develop a reference multilingual lexicon for raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) to perform comparative sensory tests through panels operating in different countries using their native language. Attributes were collected from state-of-the-art literature and integrated with a detailed description of the sensory stimulus associated with each term. A panel of sensory judges was trained to test lexicon efficacy. After training, panelists evaluated three cultivars of blueberry and raspberry through RATA (Rate All That Apply), which allowed missing attributes to be excluded while rating those actually present. Results showed the discerning efficacy of the lexicon developed can be a valuable tool for planning sensory evaluations held in different countries, opening up further possibilities to enrich blueberry and raspberry descriptor lists with emerging terms from local experience and evaluations of berry genotypes with peculiar traits.
