Response of Local and Roma Tomato Varieties to (0.2mM) Concentration of Sodium Azide (NaN3) in Dry Season

The Response of Local and Roma Tomato Varieties to 0.2mM Concentration of Sodium Azide (NaN3) in Dry Season, was investigated with the aim of inducing variability that could be exploited in the improvement of some quality traits in Tomato. The Roma variety was said to be flourishing more during Rainy season. The seeds of the two varieties of tomato: (Roma and Local varieties) were treated with concentrations of sodium azide (0.2mM).The result indicated that, the interactions makes all the two varieties of tomato to respond more to the mutagenic treatments during the dry season. The interaction showed that, seedlings height, height at maturity and pericarp thickness have the highest response during the dry season. However, all the mutants treated with 0.2mM concentration showed higher response during dry season. The interactions on the local variety were not highest during season. Similarly, the interaction among the mutants of local variety treated with 0.2mM concentration was not higher during the dry season for most of the selected traits. Similar result was found among the mutants of variety Roma treated with 0.2 mM concentration of sodium azid
