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 and selection season in Homestead, Florida (F2S1). 990 F2S1 progenies were tested for per-se yield in trials at the Sandhillls Research Station in North Carolina in 1996. The top ten percent were selected for further selfing and topcrossing in a winter nursery in Homestead, Florida. 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 lodging, early flowering, synchrony of silk and pollen production, and reduced plant and ear height. This germplasm yields extremely well in the southern US in topcrosses to stiff stalk testers compared to elite hybrid checks. The kernels are yellow in color and semident in texture. It has good per se grey leaf spot resistance. | 1625382 | PI 639497 |
