Sorghum Accessions for Use as Cover Crops and Biofuel Feedstocks

摘要: Phenotypes of sorghum species ( Sorghum sp.) have characteristics making them valuable summer annual cover crops and/or biofuel feedstocks for temperate climates. In field studies conducted at Urbana, IL, USA, fourteen USDA landrace accessions and three commercial were evaluated their growth habits regrowth potential. Canonical Discriminant Analysis (CDA) analysis, the first two canonical variates significant accounted 86% among-accession variability. Unmown tiller number, biomass best discriminated between in CDA scattergrams. The clustered into subgroups. Three multi-stemmed (two varieties one accession) with an ability to regrow away from bulk sorghums. Multi-stemmed are useful breeding improved that tall, produce copious amounts biomass, rapidly after defoliation; although propensity lodging poor germination will need attention. Additionally, germplasm collection crop feedstocks, due great height production, it be necessary select Crosses landraces commercially available could lead a plant following defoliation.
