Abstract:

The Response of tomato variety (UC-82B) to colchicine and seasonal variations to improved growth and yield related traits was investigated with the aim of inducing variability that could be exploited in the improvement of some quality traits in Tomato. The seed of the tomato variety (UC-82B) was treated with three different concentrations of colchicine (1.0mM, 1.5 mM, 2.0 mM and 0.0 mM as control). The result indicated that, the interaction makes (UC-82B) variety of tomato to respond more to the mutagenic treatments during the rainy season than the dry season. The interaction showed that, seedlings height, height at maturity and pericarp thickness of the controls have the highest response during the dry season. However, the (UC-82B) mutant treated with 1.0mM concentration showed highest response in all the selected traits during rainy season except fruit diameter. Similarly, all the 1.5mM treated mutants showed highest response during rainy season except in leaf area where highest response was found in dry season. Similar result was found in 2.0 mM treated mutants.
