Four lines currently are being evaluated in the AMBA Pilot Scale Evaluation Program.
The lines are ND20299 (ND16924/ND17082), ND20448 (ND16918/C98-10-155-3),
ND20508 (ND16918*2/CIho 6610), and ND21306 (Drummond*2/FEG4-66L). ND20448
and ND20508 are in their second year of Pilot Scale Evaluation and both were rated
satisfactory last year by AMBA. ND20299 and ND21306 are in their first year of
evaluation. Based on unacceptable agronomic and DON data from 2006 (data not
presented), ND20508 will not be evaluated in yield trials in 2007. ND20299, ND20448,
and ND21306 will be evaluated in 2007 and comparisons of these lines to currently
grown varieties are presented in Tables 3-8.
