| origin and evolution of andigena potatoes revealed by chloroplast and nuclear dna markers. | andigena potatoes (solanum tuberosum l. subsp. andigena hawkes) (2n = 4x = 48) are important, native-farmer-selected cultivars in the andes, which form a primary gene pool for improving a worldwide grown potato (s. tuberosum subsp. tuberosum). to elucidate the origin of andigena, 196 andigena accessions were compared with 301 accessions of 33 closely related cultivated and wild species using several types of chloroplast dna (ctdna) markers and nuclear dna (ndna) restriction fragment length polym ... | 2006 | 16936843 |
