1. Unlocking breeding potential of African
crops through data management an
example with CASSAVABASE

6. ● Multi trait and Multi breeding environments for cassava
phenotypic data collection
● Large scale production of genomic data using GBS
● Integrate Genomic Selection tool via web interface
What are the major challenges?
● Make the most of this resource for cassava breeders:
speed up the analysis and decision making
7. What are the needs?
● Search various data types (phenotypes and germplasm) in a large datastore
● Manage data and daily breeding activity through comprehensive interface
● Analyse and retrieve data for genomic assisted breeding
What are our solutions?
● Integrate phenomic & genomic data with breeding tools
● Use Perl with the Bio::Chado::Schema and Natural Diversity
module as database architecture
● Retrieve genomic information
● Sequence visualization ● Open source

27. CASSAVABASE, a User perspective: support & interaction
-> Provide support on technical issues ( data management)
-> Gather user request for tool improvement and new developments
(pedigree queries, VIGS)
-> 2016: Install Mirror site @ IITA Ibadan, Nigeria
Weekly meetings with users in Africa: Wiki, FB pages & mailing list:
28. CASSAVABASE Upcoming developments
Search: Integrate trait & values in the wizard search
Manage: extract data subset according to their phenotypic
values, conditionnal choices
Analyze: -Phenotypic analysis developments (ANOVA, GxE)
-Pedigree analysis
-Jbrowse: Mutation prediction of genetic variants
-SolGS: Jobs queuing, trial selection improvement
