Abstract


The seeds of tomato (Lycopersicon esculentum L.) variety Roma VF obtained from Institute of Agricultural Research (IAR), Ahmadu Bello University Zaria, were treated with Colchicine and Paradichlorobenzene with the aim of determining the effectiveness of the mutagens in the production of variations in Tomato. Highly significant difference were observed for germination percentage, number of leaves, and height at maturity. Seedling height, number of branches and germination percentage decrease with increase in concentration of Colchicine and there was increase in leaf length, height at maturity with increase in concentration. While there was highly significant difference in germination percentage, number of leaves, and significant difference in leaf length and height at maturity for Paradichlorobenzene. There was decrease in all the traits that were studied; however, there was increase in seedling height, leaf length, and number of branches with increase in concentration. Paradichlorobenzene showed the highest effect in seedling height, germination percentage at both 5 and 8 days respectively. While colchicines showed the highest effect only in number of branches.Therefore, the use of 1mm and 4mm Colchicine and Paradichlorobenzene is recommended for inducing mutation to create variability and thus increase the possibility of isolating beneficial mutants.
