Results are par-ticularly helpful to grain sorghumproducers in selecting hybridsjsuited to their area.We tested 38 commercial andI experimental hybrids at five,locations in Mississippi in 1976I(Table 1). Because a true test of' performance cannot be madewithout control of insects, insec-ticides were applied as needed (twoapplications of a recommendedinsecticide usually are sufficient^).Resistance to diseases is impor-tant in selecting a hybrid for areaswhere diseases are a problem. Also,)planting at the recommended time;will reduce damage caused bydiseases and insects,jQuantity of harvested good-' quality grain (or silage) is the bestjguide to the desirability of sorghumA randomized complete blockexperimental design with fourreplications was used at allIlocations. Each plot consisted oftwo rows, 38 or 40 inches wide and20 feet long. All trials were planted'Iat the rate of seven pounds of seedhybrids. Performance data for anyone year may be misleading.Therefore, performance of eachhybrid tested in 1976 is presentedTesting Proceduresper acre. Areas of 1 /lOOO of an acrewere hand-harvested from eachreplication, heads were dried andthreshed, and grain yield wasadjusted to 14 percent moisture.Trials with average bird damage ofmore than 25 percent were notin this report along with three-yearaverages of performances ofhybrids that have been tested forthis long.harvested.
