Two transgenic potato lines csr2-1 and csr4-8, containing two different antisense constructs, csr2 and
csr4, respectively, were crossed to investigate the possibility of achieving double transformants with
combined effects of the two antisense transgenes on plant phenotypes and cellulose deposition.
Molecular analysis revealed an expected segregation ratio of 1:1:1:1 of the four classes. Phenotype
characterization revealed that offspring containing either one or both transgenes produced more tubers
than the control plants but individual tubers were mostly smaller and had lesser weight than the control
