“…Potato virus Y (PVY) strains can be classified at least into three groups, of which PVY 0 and PVY N are the most important. Breeding for resistance is easier than in the case of PLVR because markers for the presence of the ry adg gene were found there (Uhrig et al 1992). These markers are based on a different n-like sequence that was mapped to the same resistance location on potato chromosome 6, which includes ry and PLrV1 (Kasai et al 2000).…”

“…The species S. phureja and S. stoloniferum are sources of such genes (Ross 1986). Sources of PVY resistance became also available from somatic hybrids between S. brevidens and S. tuberosum (Pehu et al 1990) and this resistance seems active also against PLRV and PVX ( Uhrig et al 1992). …”

“…A disastrous epidemic attack on potatoes in the middle of the 19 th century forced the breeders to introduce a new resistant germplasm (Uhrig et al 1992). Previously, wild species from Mexico were used; therefore around 80% of current potato cultivars have late blight resistance genes introduced from the species such as S. demissum, S. chacoense and S. phureja (Uhrig et al 1992;Pérez et al 2000).…”

“…The antecedent sources for resistance to e. carotovora were obtained via somatic fusion between S. tuberosum and the non-tuber-bearing wild species S. brevidens. The fusion hybrids produced highly resistant tubers (Uhrig et al 1992). New sources of polygenic resistance to e. carotovora subsp.…”

The potato belongs to Solanaceae, the family of about 90 genera and 2800 species. The genus Solanum consists of about 2000 species (Volkov et al. Abstract: Wild potato species (genus Solanum, section Petota) represent a tremendously diverse gene pool which is traditionally utilized as a source of diverse traits for potato breeding. Abiotic and biotic stress tolerance and resistance belong to the most frequently utilized traits of wild species in potato breeding programs. This review provides an introduction to the taxonomy, centre of diversity, genetic characteristics, evolution and important tolerance and resistance traits of wild potatoes and their use for potato breeding. The review has been written for readers who are interested in the problems of finding and utilization of new resistance genes from the wild genetic resources. REVIEW

“…In addition, the disease is the major cause of seed tuber losses in the tropics. Different levels of resistance are found in wild relatives, but progress in breeding has been very slow so far (Fock et al 2000;Kim-Lee et al 2005;Uhrig et al 1992).…”

Sequencing the Potato Genome: Outline and First Results to Come from the Elucidation of the Sequence of the World’s Third Most Important Food Crop

et al. 2009

Potato is a member of the Solanaceae, a plant family that includes several other economically important species, such as tomato, eggplant, petunia, tobacco and pepper. The Potato Genome Sequencing Consortium (PGSC) aims to elucidate the complete genome sequence of potato, the third most important food crop in the world. The PGSC is a collaboration between 13 research groups from China, India, Poland, Russia, the Netherlands, Ireland, Am. J. Pot Res (2009) Argentina, Brazil, Chile, Peru, USA, New Zealand and the UK. The potato genome consists of 12 chromosomes and has a (haploid) length of approximately 840 million base pairs, making it a medium-sized plant genome. The sequencing project builds on a diploid potato genomic bacterial artificial chromosome (BAC) clone library of 78000 clones, which has been fingerprinted and aligned into~7000 physical map contigs. In addition, the BACends have been sequenced and are publicly available. Approximately 30000 BACs are anchored to the Ultra High Density genetic map of potato, composed of 10000 unique AFLP TM markers. From this integrated geneticphysical map, between 50 to 150 seed BACs have currently been identified for every chromosome. Fluorescent in situ hybridization experiments on selected BAC clones confirm these anchor points. The seed clones provide the starting point for a BAC-by-BAC sequencing strategy. This strategy is being complemented by whole genome shotgun sequencing approaches using both 454 GS FLX and Illumina GA2 instruments. Assembly and annotation of the sequence data will be performed using publicly available and tailor-made tools. The availability of the annotated data will help to characterize germplasm collections based on allelic variance and to assist potato breeders to more fully exploit the genetic potential of potato.Resumen La papa es un miembro de las Solanaceae, una familia de plantas que incluye varias otras especies económicamente importantes, tales como tomate, berenjena, petunia, tabaco y ají o chili.
