Narrative

Thai hybrid DK888 crossed to proprietary stiff stalk line from GEM "company 11". Germplasms were developed by selfing and selecting variable F1s from tropical-source x US inbred crosses in North Carolina under standard nursery conditions, followed by a second selfing/selection season in Homestead, FL (F2S1), and a third selfing/selection season in a selection nursery in Raleigh (F2S2). All procedures were carried out using ear-to-row methods, except that F2 seeds planted in Homestead were bulked by pedigree. Germplasms were selected on the basis of resistance to a mixture of foliar diseases (Southern and Northern Leaf Blight, Anthracnose, Gray Leaf Spot), resistance to Fusarium ear rot, resistance to Anthracnose stalk rot, resistance to lodging , early flowering, synchrony of silk and pollen production, and reduced plant and ear height. This germplasm yields well in the southern US in topcrosses to non-stiff stalk testers compared to elite hybrid checks. It also yielded relatively well in topcrosses in the Midwest compared to other released GEM germplasm of a similar derivation. It flowers at approximately the same time as B73 in the southern US. It has common rust and gray leaf spot resistance and produces orange kernels, semident in texture.
