Rezumat | ||||||
Synaptic mutants of tomato as1, dsm1, dsm2 revealed a reduction in the frequency of chiasmata in meiotic cell and normal level of recombination frequency. Mutants which were characterized by impaired chromatin condensation, showed a significant increase in the frequency of crossing-over in homo-and heterozygous state. The phenomenon of incomplete recessive mutant allele (or overdominance normal) allowed usage of heterozygous plants in breeding with a view to expanding the range of combinative variability. |
