Compare the cytological stability, meiotic chromosome behavior, and genetic transmission in tetraploid tomato lines established from distinct origins.
Examined chromosomal configurations and meiotic division stages in tetraploid Solanum lycopersicum lineages derived via different developmental routes.
Assessed multivalent formation frequency, chromosome pairing regularity, and gamete viability across lineage sources.
Meiotic chromosome associations varied significantly between tetraploid lineages, showing divergent frequencies of bivalents and quadrivalents based on biological origin.
Disparities in chromosome segregation directly corresponded to differences in pollen sterility and reduced seed set between lines.

Implication

Cytogenetic investigation demonstrates chromosome behavior differences in tetraploid tomatoes of distinct origins, highlighting structural variations induced by polyploidy.
