CloneSelector Users guide – Potato

CloneSelector is a tool developed to help plant breeder carry out field trials. In version 1.1 the functionality is focused on the process of carrying out a trial to test a list of germplasm, and it may help you in the following task:

  1. Elaborate list of germplasm to test
  2. Design of field trial with one or more experiments
  3. Generation of a field book for each experiment
  4. Register metadata for each experiment
  5. Data collection in field and post harvest for each entry
  6. Enter collected data into electronic field book
  7. Calculation of derived variables (yield/ha etc)
  8. Statistical analysis of trial
  9. Elaboration of consolidated result table for each trial


The CloneSelector is based on the Maize Fieldbook developed by CIMMYT, and this tool has many additional functions especially related to seed management. For clonally propagated crops this functionality is not adequate and it has been eliminated in CloneSelector, however, for seed based crops it might be better to use the original Maize Fieldbook, which is available at CIMMYT. The current version of CloneSelector is targeted at sweetpotato, but it can be used for any crop as long as the trial template is adapted to include the relevant traits.

The CloneSelector for Potato is based the Procedures for standard evaluation trials of advanced potato clones. An International Cooperators’ Guide, CIP (2007) (ICG), and as such it is a practical tool that aims to help the potato breeders put these standardized methods into practice, and by doing that it aims to improve the efficiency and effectiveness of the breeding effort. The Procedures have been incorporated into the user’s guide in order to facilitate the learning and adoption of both tools. Furthermore, the process of operationalizing the procedures in a specific tool has lead to some minor adjustments on how the information is structured or presented, and the User Guide presents these changed data formats. Also in order to keep CloneSelector relatively simple to use, it only includes the most common traits used for potato breeding, and not the full range covered in the ICG.
