Comparison of growth, forage yield and nutritional quality of diploid and autotetraploid maize synthetics

Three autotetraploid maize synthetics were compared with four diploid synthetics of similar adaptation in yield trials and growth analysis experiments at several southern Ontario locations, in order to assess the potential of tetraploid maize as a source of forage. No differences were observed among...

Description
Summary:Three autotetraploid maize synthetics were compared with four diploid synthetics of similar adaptation in yield trials and growth analysis experiments at several southern Ontario locations, in order to assess the potential of tetraploid maize as a source of forage. No differences were observed among ploidy levels in productivity of whole-plant dry matter, or in nutritional quality of forage. Tetraploids appeared to be lower in dry matter content at harvest and through much of their period of growth.Key words: Silage corn, forage corn, autotetraploid, (Zea mays L.)
