Implication

Experimental study demonstrates physiological variability and low ploidy transmission in common bean, indicating limited inheritance of induced tetraploidy.

Key Points

To assess how colchicine-induced polyploidy affects stomatal traits, photosynthetic physiology, oxidative stress responses, and generational ploidy inheritance in Phaseolus vulgaris cv. Zorzal.
Induced polyploidy in Phaseolus vulgaris cv. Zorzal using variable colchicine exposure regimes and confirmed ploidy levels via flow cytometry.
Evaluated gas exchange, stomatal anatomy, photosynthetic pigments, oxidative markers, antioxidant capacity, and ploidy transmission in C1 progeny.
Colchicine treatment successfully generated mixoploid and tetraploid plants, though induction efficiency varied widely among replicates.
Tetraploid lines exhibited heterogeneous physiological profiles, including increased photosynthetic rates and stomatal conductance in specific genotypes without consistent reductions in stomatal pore area index.
Transmission of the tetraploid state was unstable, with C1 generation offspring showing a predominance of diploid progeny.
