Cattle production in Florida is limited by the lack of available warm-season forages adapted to the cool winters of the region Setaria (S.sphacelata) has demonstrated green growth during cool conditions in subtropical climates around the word, and has the potential to fill this niche in cattle production in Florida. Four populations were selected in Gainesville and Ona. Florida: two cycles of selection for increased head number, one cycle for incresede leaf width and one cycle for grazing tolerance. The objetives of this research were to compare these populations morphologically to determine changesdue to selection. Selection for leaf width increased this trait while maintaining other morphological characteristics constant. Selection for head number decreased plant height and increased head number in each cycle, and decreased leaf width and inflorescence length in the second cycle. Selection for grazing regrowth resulted in reduced plant height and inflorescence length. Concern regarding susceptibility of setaria to chinch bug and possible winter killing in Florida remain to be resolved before this species may be commercialized in Florida. |
