“…Examination of allelic diversity of potato S-genes has demonstrated its significant limitation [29]. The data obtained in our laboratory suggest that the results of hybridization of certain S. tuberosum dihaploids may be explained by the fact that they contain no more than four S-alleles.…”

A b s t r a c tIt is important for improving the efficacy of potato breeding to have parental lines that are multiplex for many genes of agronomic characters, first of all genes of resistance to pests and diseases (that have two or more dominant alleles in the locus) (J.E. Bradshaw et al., 1994). Parental lines that are multiplex for several resistance genes occur not often (A.P. Yermishin et al., 2016) and, owing to biological peculiarities of potato crop, they can be produced only by means of breeding at the diploid level. In the presented review the genetic principles are described and an experience of their use by authors in research devoted to the development of the initial material applicable for effective marker assisted potato parental line breeding at the diploid level. The material includes the collection of initial dihaploids originated from potato varieties which were selected for viability, tuber performance, cultivar characters and DNA-markers of pest and diseases resistance genes; the diploid breeding material having wide range of late blight and virus resistance genes, introgressed from wild potato species by means of original methods of overcoming interspecific reproductive barriers; the diploid lines -donors of self-incompatibility gene and high male fertility genes that are effective as in heterozygous as well as in homozygous condition; the diploid lines -donors of genes of male fertile FDR (first division restitution) 2n-gamete formation. The best diploid lines having a complex of pest and diseases resistance genes, selected as the result of diploid breeding (on the basis of initial dihaploids, interspecific hybrids and donors of fertility) were used for production of multiplex tetraploid parental lines by means of mitotic chromosome doubling. Diploid parental lines suitable for hybridization with potato varieties (for meiotic polyploidization) were bred using lines-donors of genes of male fertile FDR 2n-gamete formation. The diploid initial material developed as the result of the research is of the interest for prospective alternative directions of potato breeding using selection at the diploid level: breeding diploid potato varieties as well as parental lines for production of hybrids and hybrid populations for true potato seed technology.

“…SC diploid clones can be engineered by the introduction of an extra SLF gene to induce competitive interaction, or by knock-out of the S-RNase (Enciso-Rodriguez et al, 2019;Ye et al, 2018) or other essential genes such as HT (Kondo et al, 2002). Alternatively, SC can be introgressed from natural mutants since SC clones have been spotted among several SI relatives of potato (Cipar et al, 1964). For instance recently described the S. stenotomum landrace Huasa Amarilla (a.k.a.…”

The origin and widespread occurrence of Sli based self-compatibility in potato Chapter 3 46 High-density linkage map constructed from a skim sequenced diploid potato population reveals transmission distortion and QTLs for tuber yield and pollen shed Chapter 4 74Desynapsis in potato is caused by StMSH4 mutant alleles and leads to either highly uniform unreduced pollen or sterility Chapter 5 94Identification of two mutant JASON-RELATED genes associated with unreduced pollen production in potato Chapter 6 122 General discussion References 143Summary 167Acknowledgements 171 About the author 179Education statement recognition model (Kubo et al., 2010), the combined action of the SLFs encoded by one S-haplotype results in the recognition and degradation of all S-RNases except of the one encoded by their own haplotype. Hence, self-incompatibility occurs when the Shaplotype of the pollen matches either of the two S-haplotypes of the style. This elegant model also provides an explanation for the phenomenon of competitive interaction that allows tetraploid potatoes to become self-compatible (Olsder and Hermsen, 1976). When tetraploid clones produce diploid heteroallelic pollen that expresses two complementary sets of S-locus F-box proteins (SLFs), all S-RNases are ubiquitinated, which breaks down gametophytic self-incompatibility.Recently, self-compatible diploid potato clones were engineered by a knock-out of the gene encoding for the S-RNase (Enciso-Rodriguez et al., 2019;Ye et al., 2018). Furthermore, a self-compatible diploid clone bearing a naturally weakly expressed S-RNase was recently identified . Other cases of self-compatibility among S. tuberosum dihaploids were reported in earlier studies (De Jong and Rowe, 1971;Olsder and Hermsen, 1976), but the genetic and mechanistic basis of their selfcompatibility remained undetermined prior to this thesis. Despite those alternative options, the most widely used source of self-compatibility is the dominant gene Sli originally identified from a S. chacoense accession and located on chromosome 12 Hanneman, 1998a, 1998b). The causal gene behind Sli was recently shown to encode for a pollen-expressed F-box protein functioning as a general S-RNase inhibitor (Eggers et al., 2021;Ma et al., 2021).
