SummaryConventional potato breeding does not make full use of the existing biodiversity within theSolanum genus. Moreover breeding at the 4x-4x level is slow. The potential for breeding at the diploid and dihaploid levels has therefore been explored. This requires use of novel techniques to overcome deviations from the desired Endosperm Balance Number.Somatic hybridization approaches include symmetric and asymmetric hybridizations and cybridization. Interesting traits have been successfully… Expand
Production of potato intraspecific somatic hybrids with improved tolerance to PVY and Pythium aphanidermatum.
All hybrids showed improved tolerance to Pythium aphanidermatum infection during tuber storage or after plant inoculation and the effect of potato virus Y infection on these hybrid lines was tested by mechanical inoculation of plants cultivated in a greenhouse. Expand
Development of intermonoploid somatic hybrids of potato and their molecular analysis based on polymorphism for retroelement Tst1
Sequence specific amplified polymorphism (S-SAP) represents a hybrid system incorporating amplified fragment length polymorphisms (AFLP) technology in conjunction with the use of a defined genomic sequence, e.g., retrotransposon display (RD) when the defined sequence is anchored into a consensus sequence of a retrotransposition such as the long terminal repeat (LTR) sequence of Tst1.

Somatic hybrids between potato Solanum tuberosum and wild species Solanum verneï exhibit a recombination in the plastome
The RAPD analysis of genomic DNA and microsatellite based amplification (I-SSR) showed that both clones VB1 and VB2 are asymmetric somatic hybrids, suggesting that both hybrid plastomes were the result of a recombination between parental ones. Expand
Stoloniferous shoot protoplast, an efficient cell system in potato for somatic cell genetic manipulations
It is reported that protoplasts isolated from stoloniferous shoots (SS) of potato represent an efficient system for somatic cell genetic manipulations and are found to be most responsive for symmetric somatic hybridization (electrofusion) between Solanum tuberosum Gp. Expand
QTL for field resistance to late blight in potato are strongly correlated with maturity and vigour
The absence of Solanum demissum-derived R genes for hypersensitive response to late blight and the co-localisation of QTL for resistance, vigour and earliness suggest that developmental and/or physiological factors play a major role in determining the level of foliage resistance in this population.

Use of Polyethylene Glycol (PEG) 8000 for Rapid Screening of Potato (Solanum tuberosum L) Genotypes for Water Stress Tolerance
RLDR and RDWR show promise for selecting potato genotypes grown in vitro for drought tolerance and the linear correlations of RLDR andRDWR results over runs of the experiment were significant, suggesting that the results were consistent. Expand
Interspecific hybrids of potato : determination of glycoalkaloid aglycones and influence of bacterial infection
The author’s contributions are listed, as well as those of the authors themselves, which are listed below. Expand
Morfološka i molekularna komparativna analiza dihaploidnih i F2 samooplodnih linija u selekciji kukuruza
U radu je procijenjena pogodnost metode indukcije haploida in vivo za uporabu u oplemenjivanju i selekciji kukuruza. Ciljevi istraživanja bili su: 1.


Breeding for nematode and virus resistance in potato via anther culture
Using anther culture it is demonstrated that doubled monohaploid clones can be produced which possess the resistance in the homozygous condition, and the potentiality for regeneration is under genetic control and can be utilized by combination breeding. Expand
Somatic Hybridization of Dihaploid Potato Protoplasts as a Tool for Potato Breeding
The results indicate that factors such as ‘combining ability’ strongly influence hybrid formation in these intraspecific fusion experiments, and confirm that monogenic dominant inherited traits are combined in the hybrids. Expand
Comparison of single cell culture derived Solanum tuberosum L. plants and a model for their application in breeding programs
SummaryThe techniques of microspore and protoplast regeneration starting from dihaploid Solanum tuberosum plants has been improved to such an extent that the production of more than 2000 microsporeExpand
Tetraploid potato hybrids through protoplast fusions and analysis of their performance in the field
The results of this study prove that fertile tetraploid somatic hybrids having similar or higher tuber yield than that of cv Bintje can be obtained through somatic hybridization. Expand
Interspecific somatic hybridization in potato by protoplast electrofusion
Somatic hybrid plants produced after protoplast electrofusion with the objective of transferring insect resistance, which is associated with the presence of glandular hairs, into potato lines exhibited several morphological traits intermediate to both parents including plant habit, leaf form, and particularly short four-lobed glandular trichomes inherited from the wild parent.

Production and analysis of intraspecific somatic hybrids of potato (Solanum tuberosum L.)
It is shown that tetraploid somatic hybrid potato plants can be obtained by the fusion and selection method presented and the majority of the hexaploid hybrids contained 2 genomes of the bleached parent and one genome of the mesophyll parent. Expand
Sexual progeny of somatic hybrids between potato andSolanum brevidens: Potential for use in breeding programs
Results indicate that interspecific somatic hybridization can produce material with potential for use in a potato breeding program and indicate that the hibridación somática interespecífica puede producir material with potencial for ser utilizado in un programa of mejoramiento de papa. Expand
Production and characterization of haploids derived from somatic hybrids between Solanum brevidens and S-tuberosum through anther culture
The somatic hybrids were identified as chimeric (hypohexaploids), whereas the haploids derived from them using anther culture were all triploids according to flow cytometry, and were extremely resistant to potato leaf roll virus. Expand
Haploidy in important crop plants - potato.
Solanum tuberosum L. (2n = 4x = 48), the cultivated white or Irish potato, is the world’s fourth major economic crop and its hybridization often results in the production of tetraploid hybrids. Expand
Characterization of somatic hybrids of potato by use of RAPD markers and isozyme analysis
Morphological assessment of the putative hybrids revealed that tetraploid and near-tetraploids hybrids were vigorous plants with intermediate characteristics between the two parental phenotypes in respect to internode length, leaf size and shape, and purple pigmentation on the abaxial side of the leaves.
