Means for measured characteristics for transgenic RNAi doubled haploid lines and associated checks.

a For convenience, genotypes are presented in three groups: four RNAi lines with non-significant changes in nicotine content, six RNAi lines with significant observed reductions in nicotine content, and three non-transgenic checks.b % total alkaloids was calculated as: % total alkaloids = (% nicotine + % nornicotine + % anatabine + % anabasine + % DMN).c ND = non-detectableMeans for measured characteristics for transgenic RNAi doubled haploid lines and associated checks.
