Molecular Support for the Hybrid Origin of the Wild Potato Species Solanum 3 rechei A. M. Clausen* and D. M. Spooner ABSTRACT (Spooner and van den Berg, ). Eleven of the puta-Twenty-seven of the wild potato species (Solanum sect. Pet- tive hybrids are diploid, six triploid, three tetraploid,ota) have been hypothesized to be of natural hybrid origin. Introduction. The Solanaceae family comprises – species that are classified in approximately 90 genera. The family is highly diverse, includes perennial trees as well as herbaceous annual species and occupies a wide range of terrestrial habitats from deserts to rainforests (Knapp et al. ).Compared with the large size of the family, only few .
Both diploid (S. phureja and S. stenotomum Juz. et Buk.) and tetraploid (S. tuberosum subsp. andigena) primitive cultivated forms were included. Seeds from each PI were soaked for 24 h in mg L–1 gibberellic acid, washed in 10% bleach solution, rinsed with sterile water, and germinated on filter paper under ambient light. The present document represents a companion document to the Dir ective (Dir), entitled Assessment Criteria for Determining Environmental Safety of Plants with Novel Trait. It is intended to provide background information on the biology of Solanum tuberosum (L.), its centres of origin, its related species and the potential for gene introgression from S. tuberosum into .

Summary. The variation in Solanum × chaucha Juz. et Buk. (2n=3x=36) was studied using accessions from the Potato Collection maintained by the International Potato Center.
These accession represented less than 5% of the collection originally screened for by: Summary. The possibility of combining anew the genomes of wild and cultivated progenitors of triploid S. x juzepczukii and pentaploid S.

Home of the potato The Andes of South America are the home of the potato that has supported indigenous civilizations for thousands of years. As many as 4, native potato varieties are still grown.
The region around Lake Titicaca in southern Peru and northern Bolivia is particularly rich in genetic diversity, and the wild potatoes. The present review seeks to bring together different proposals about the taxonomy of cultivated potatoes and their tuberbearing wild relatives (Solanum L.
sect. Petota Dumort.). The taxonomy of wild and cultivated potatoes (Solanum sect. Petota) is complicated by sexual compatibility among many species, interspecific hybridization, introgression, a mixture of sexual and asexual reproduction, auto‐ and allopolyploidy, possible recent species divergence, phenotypic plasticity, and consequent great morphological.
Wild potato relatives are rich sources of desirable traits for introgressive hybridisation into cultivated potato. One of them, Solanum commersonii (2n = 2x = 24, 1EBN, endosperm balance number.

Petota Dumort., the potato and its wild relatives, is distributed from the southwestern United States to south-central Chile, with a concentration of diversity in the Andes.
The base chromosome number for the Solanum genus is x = 12, with most potato species (wild and cultivated) being diploid (73%), and a few being triploid (4%), tetraploid (15%), pentaploid (2%) or hexaploid (6%).
58 Some important potato species are listed in Table The majority of the 2x potato species are outbreeders due to gametophytic. 1. Introduction. Western South America is the primary center of the origin and diversity of the potato crop and its wild relatives.
Contemporary landrace gene pools occur from 45° south in Chile to 12° northern latitude in Colombia (Hawkes, ).Wild relatives of the potato (Solanum section Petota; Solanaceae) have a much wider distribution range and .The cultivated potato of world commerce, Solanum tuberosum L., is a primary food crop grown and con-sumed worldwide, forming a basic food and source of primary income for many societies.
Indigenous primi-tive cultivated (landrace) and wild (Solanum section Petota) potatoes form the raw germplasm base used for breeding advanced potato varieties.
