Seven Solanum tuberosum ssp. tuberosum and three Solanum tuberosum ssp. andigena accessions were crossed to produce 12 Tuberosum × Tuberosum (T × T) and 9 Tuberosum × Andigena (T × A) progenies. These families were evaluated for five important traits for two successive clonal generations under short day sub-tropical plains.

Origin and evolution of Andigena potatoes revealed by chloroplast and nuclear DNA markers [PDF]
Genome, 2006 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 ...

Variation in antioxidant status and productivity in andigena potato clones
Indian Journal of Plant Physiology, 2014Potato can be a valuable source of antioxidants in the human diet, and genetic variability exists for antioxidant contents. The present study was carried out to evaluate the extent of variability in coloured flesh potatoes from andigena clones. There were significant differences among clones in ascorbic acid, phenols, total carotenoids and anthocyanins.

Genetic variation in the response of andigena potatoes to inorganic fertilizers
Potato Research, 1992Tuber yield, dry matter and true protein content were studied in 24 andigena potato genotypes. Their performance and response differed greatly and significantly when grown at three levels of inorganic N, P and K fertilizer application. In general, tuber yield and protein content increased with increased fertilizer level, whereas dry matter content ...

PACHYTENE CHROMOSOMES OF THE POTATO (SOLANUM TUBEROSUM, GROUP ANDIGENA)
American Journal of Botany, 1965The morphology of the pachytene chromosomes of haploids (2 n = 24) of Solanum tuberosum Group Andigena (2 n = 48) is described.

Molecular Phylogenetics and Evolution, 2013
Andean uplift, Plio-Pleistocene climatic fluctuation, and river dynamics in the Amazon basin have all been implicated in the diversification of the South American avifauna. We reconstructed phylogenetic relationships in the genus Selenidera, which has served as a classic case of putative refugial speciation, and the closely related genus Andigena, to ...

Heterosis and combining ability ofSolanum tuberosum Group Andigena haploids
Potato Research, 1982Combining ability analysis was done on a diallel cross of a random sample of four different cultivated diploid potato populations (Solanum tuberosum Group Andigena haploid, Gp. Tuberosum haploid, Gp. Phureja and Gp. Stenotomum) to determine the amount of heterosis and the gene action involved in the inheritance of tuber yield, fresh vine yield, total ...

Nitrogen Use Efficiency Characteristics of Andigena and Diploid Potato Selections
American Journal of Potato Research, 2008Considerable effort has been made to develop management practices to reduce environmental losses of nitrogen (N) from potato production systems. Increasing the efficiency of N utilization by the potato crop is one approach to reducing environmental losses of N.

Further sources of resistance toHeterodera rostochiensis woll. in the andigena potatoes
Euphytica, 1970The Andigena potatoes (Solanum tuberosum ssp.andigena) of the Commonwealth Potato Collection (C.P.C.) were screened for resistance to ‘non-pathotype A’ populations ofHeterodera rostochiensis. Three populations were used: Duddingston (pathotype B), Nocton (pathotype C) and Changed Little Ouse (pathotype C). Resistance was found in C.P.C.
