Upgrade the program specification with the following fields (commented):

   "program": {
        "type":"breedingProgram", //values among: "breeding program", "project" ENUM
        "grantInformation":"EU: FP7-244374",//string
        "abbreviation": "P1",
        "additionalInfo": {  },
        "commonCropName": "Tomatillo",
        "documentationURL": "https://wiki.brapi.org",
        "externalReferences": [
          {
            "referenceID": "doi:10.155454/12341234",
            "referenceSource": "DOI"
          }, ...
        ],
        "leadPersonDbId": "fe6f5c50",
        "leadPersonName": "Bob Robertson",
        "objective": "Make a better tomatillo",
        "programDbId": "f60f15b2",

I would suggest fundingInformation instead of grantInformation to make it more general, but otherwise this seems like a good idea to me.
