Abstract: | Summary Hybridization between tomato with xx and XX gametophytic genotypes exhibited in segregating generations, deviations from the expected monogenic inheritance of Fusarium wilt resistance conditioned by gene I. These deviations resul ted from gametophytic preference, linkage and the presence of modifying loci associated with the gene I. Although information on the inheritance of Fusarium wilt resistance is based on backcross data, information obtained from the pedigree procedure and testcrosses made with BC1S2 plants all supports the presence of modifiers.Michigan Agricultural Experiment Station Journal Number 5457. |
