dscf0991Expansion of the biofuel industry will require identification of suitable feedstock for particular geographic regions and optimization of production capacity by enhancing research-based management practices. To identify potential biofuel feedstocks, numerous cool-season oil-seed crops were evaluated for their yield potential and quality in Texas; forty-five genotypes of four winter and spring-type oilseed crops were evaluated at nine Texas A&M AgriLife Research and Extension Centers across the state. All trials were evaluated under low input rain-fed conditions. Spring rapeseed and safflower were the highest yielding crops with yields reaching 1372 kg ha-1 and 1240 kg ha-1, respectively. The oil content of safflower was lower than all other evaluated crop species. In South and Central Texas, fall seeded flax yields averaged 1075 kg ha-1 with an average oil concentration of 38.3 % (w/w); however, flax yields were low at all North Texas locations. Camelina yields, 473 kg ha-1, were lower than other evaluated crops, especially in South and Central Texas. Several cool-season oil-seed crops would be considered economically competitive with other winter grown small grain crops in Texas.
