Ramírez, D.Gavilan, C.Barreda, CarolinaCondori, B.Rossel, G.Mwanga, R.O.M.Andrade, M.I.Monneveux, P.Anglin, Noelle L.Quiróz, R.Ellis, D.Quiróz, R.[Characterizing the diversity of sweetpotato through growth parameters and leaf traits: Precocity and light use efficiency as important ordination factors.]Characterizing the diversity of sweetpotato through growth parameters and leaf traits: Precocity and light use efficiency as important ordination factors.

The International Potato Center holds one of the largest and most diverse potato cryobanks worldwide. The cryo-collection includes 1855 landraces, belonging to seven potato species and four different ploidy levels. The potato cryo-collection was principally built up in recent years (2013-17), und...

Breeders rely on genetic integrity of material from genebanks; however, admixture, mislabeling, and errors in original data can occur and be detrimental. Two hundred and fifty accessions, representing paired samples consisting of original mother plants and their in vitro counterparts from the cul...

The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that r...

The history of CGIAR and the development and implementation of the International Treaty on Plant Genetic Resources for Food and Agriculture (“Plant Treaty”) are closely intertwined. In accordance with the agreements that 11 CGIAR centers signed with the Plant Treaty’s Governing Body under Article...

Cryopreservation protocols have been successfully developed for hundreds of species and thousands of genotypes in laboratories around the world. In many of the protocols, the rewarming process occurs in a rewarming solution (RS) with a high concentration of sucrose (0.8–1.2 M). Warming rate and a...

Potato, one of the most important staple crops, originates from the highlands of the equatorial Andes. There, potatoes propagate vegetatively via tubers under short days, constant throughout the year. After their introduction to Europe in the sixteenth century, potatoes adapted to a shorter growi...

BACKGROUND: Cryobanks are a secure, efficient and low cost method for the longterm conservation of plant genetic resources for theoretically centuries or millennia with minimal maintenance. OBJECTIVE: The present manuscript describes CIP’s modified protocol for potato cryopreservation, its large-...
