In Bulletin 199 of the West Virginia Agricultural Experiment Station is discussed a first generation variety cross of corn, the yield. from which exceeded that of either parent. The crossed seed was produced, as is usual in such eases, by interplanting the vari.eties arid detasseling one of them. The crossed seed so obtained and the seed of the parent varieties were planted in adjacent plats to determine the relative yields. The plats were quadruplicated in all tests except one in which they were triplicated. There were three tests carried on from 1922 to 1924, inclusive, in different sections of the state. The first generation cross referred to was Clarage x Longfellow. Clarage is a yellow dent corn that at Morgantown requires about ~ 50 days to mature, whereas Longfellow is a flint corn that requires only ~3o days to mature. Seed of Clarage was obtained from F. E. Eichelberger, Washington Court House, Ohio, and seed of Longfellow from R. Reeler, Bridgewater, Connecticut.
