Specific Influence

For tuber-bearing Solanum species, six monogenic recessive synaptic mutants, designated sy-1, sy-2, sy-3, sy-4, ds, and dsc have been reported in the literature. In the present investigation no indication for the existence of the mutant sy-1, affecting megasporogenesis only, was found. The mutant ds was confirmed to display typical desynaptic behaviour in microsporogenesis and shown to similarly affect megasporogenesis. It furthermore proved to be allelic to the mutants sy-3 and dsc. It is proposed that the mutants sy-3, ds, and dsc be uniformly designated ds-1, whereas the remaining mutants sy-2 and sy-4 (possibly identical) may be designated simply as synaptic mutant until their actual identity has been established. The observed F1 segregations generally support monogenic recessive inheritance of ds-1. However, in one cross progeny the expected mutant phenotype was not clearly expressed in contrast with its reciprocal, which might indicate cross-specific influence of the cytoplasm on ds-1 expression. The potential value and limitations of desynaptic (ds-1ds-1) mutants for potato breeding and true potato seed production are discussed.Key words: Solanum, (de)synaptic mutants, microsporogenesis, megasporogenesis, 2n gametes.

Accurate Quantification

A potato breeding population was evaluated for the presence of tolerance and resistance to Verticillium dahliae. Clones were ranked as susceptible or moderately and highly resistant based on symptom expression, and a species-specific polymerase chain reaction (PCR)-based assay was used to determine the Verticillium biomass in the bases of stems. A clone was designated as tolerant if the amount of fungus present in the host tissue was equal to or greater than the collective average amount for all clones in the symptom category above. Tolerant and resistant clones were identified in all trials, but the expression of tolerance was usually unstable across runs. The fungus was detected in some symptomless plants; on the other hand, some symptomatic plants were found to be pathogen-free. These observations emphasize the necessity of accurate quantification of the pathogen biomass in potato during Verticillium resistance breeding programs.

Late blight remains among the main problems of potato industry. Interspecific hybridization with the wild Solanum species is an efficient way to increase the resistance to this disease, though is accompanied with negative traits. To solve this problem, new sources of resistance, including resistant breeding clones with improved agronomic characteristics, are needed. In the present study, we investigated resistance of three hybrid populations derived from crossesbreeding of resistant original clone SW93-1015×adg with susceptible cultivars: ‘Аurora’, ‘Desirée’ and ‘Valor’. High predominance of the resistant plants was found among the hybrids (SW93-1015×adg)×Aurora and (SW93-1015×adg)בDesirée’. The numbers of resistant and susceptible plants within hybrid Valor’×(SW93-1015×adg) were almost equal. Results showed the efficiency of clone SW93-1015×adg as the late blight resistance source. Within each segregating population, the selection of resistant clones was possible. Clone SW93-1015×adg can be used in breeding programs for the hybridization with susceptible cultivars characterized by other useful characteristics.

The long history of potato breeding includes the numerous introgressions of resistance genes from many wild species of South and Central America as well as from cultivated species into the breeding genepool. Most R genes belong to the NLR family with nucleotide-binding site–leucine-rich repeat. The aim of this research concerns an evaluation of NLR genes expression in transcriptomes of three potato cultivars (Evraziya, Siverskij, Sudarynya), which combine genetic material from wild and cultivated potato species, and each bears intragenic markers of RB/Rpi-blb1/Rpi-sto1 genes conferring broad-range resistance to late blight. The transcriptomes of the cultivars were compared before and 24 h after the Phytophthora infestans inoculation. The induction of RB/Rpi-blb1/Rpi-sto1 transcript after 24 h of inoculation was detected in the resistant cultivars Siverskij and Sudarynya but not in susceptible cv. Evraziya. This demonstrates the importance of transcriptomic assay for understanding the results of marker-assisted selection and phenotyping. Interestingly, assembling the transcriptomes de novo and analysis with NLR-parser tool revealed significant fractions of novel NLR genes with no homology to the reference genome (from 103 (cv. Siverskij) to 160 (S. stoloniferum, 30514/15). Comparison of novel NLRs demonstrated a relatively small intersection between the genotypes that coincided with their complex pedigrees with several interspecific hybridization events. These novel NLRs may facilitate the discovery of new efficient R genes.
