ColNucleo

Get core/nuclear ecogeographical germplasm collections based only on the coordinates of the collecting sites 

This tool makes it possible to obtain representative sub-collections of the diversity of the original collections by any technician who is in charge of preserving these collections. In the case of ColNucleo, the diversity that is intended to be represented is ecogeographical and it requires an ELC map produced by the ELC mapas tool.

The concept of core collection in plant genetic resources has been underway since the 90′s. Diverse publications (click here) have popularized their use by showing their practical applications. However, to obtain these subcollections we must have phenotypic or genotypic information of the entire original collection (complete characterization studies), which reduced the possibility of application under  conditions of low or limited financial resources.

However, in recent years, a new type of core collections were designed, created and validated from ecogeographic information. In two scientific articles (Article 1 and Article 2), it is described in detail how they were obtained, and how (through ELC maps) a core collection can be determined. The ColNucleo tool incorporates this latter method to allow any germplasm curator obtain core collections taking into account the different adaptive scenarios where the collection entries have been collected.
