Development of Perennial Grain Sorghum
Abstract: Perennial germplasm derived from crosses between Sorghum bicolor and either S. halepense or S. propinquum is being developed with the goal of preventing and reversing soil degradation in the…
High proportion of diploid hybrids produced by interspecific diploid x tetraploid Sorghum hybridization
Abstract: A perennial version of grain sorghum [S.bicolor (L.) Moench] would create opportunities for greatly reducing tillage and preventing soil degradation. Efforts to select for perenniality and grain production among progeny of…
Multi-phase US spread and habitat switching of a post-Columbian invasive, Sorghum halepense
Abstract: Johnsongrass (Sorghum halepense) is a striking example of a post-Columbian founder event. This natural experiment within ecological time-scales provides a unique opportunity for understanding patterns of continent-wide genetic diversity…
Response to selection in the initial stages of a perennial sorghum breeding program
Abstract: When developed, perennial grain sorghum could provide an opportunity for more ecologically sound food production. In 2002, we initiated a perennial sorghum breeding program, using Sorghum bicolor (L.) Moench × S….
Towards a perennial biomass sorghum crop: A comparative investigation of biomass yields and overwintering of Sorghum bicolor x S. halepense lines relative to long term S. bicolor trials in northern Italy
Abstract: The purpose of this work was to assess biomass and grain yields, path modelling of yield components, and perenniality in 97 Sorghum bicolor x S. halepense (SB x SH) lines, and…
