Colchicine-induced chromosome doubling in wheat haploids

摘要

A large number (2,596) of wheat x maize hybridization-derived haploids from 38 genotypes of soft white spring wheat were evaluated for their response to colchicine treatment. Overall, 85.9% of the treated plants survived treatment and 89.9% of these produced viable seed, with a range of 46.7% to 100% among genotypes. The differential response of genotypes to colchicine treatment was highly significant (P<0.01).
