“…This finding agrees with the work ofMaluszynski et al (2001) and Pasztor et al (1985) who independently reported an increase in leaf number and leaf area among Zeamays mutants. Similar result was also reported by Nura et al (2013) on the effect of chemical mutagen in improving the number and size of sesame leaves. More so, the improvement in the quality traits of tomato due to sodium azide treatments is in conformity to the work of Adamu et al (2002) when groundnut was treated with gamma rays and Sheeba et al (2005) when gamma rays and EMS were used to treat Sesanum indicum L. where seed germination, seedling survival, plant height and pollen fertility were reduced significantly with an increase in dosage levels of both mutagens.…”

The mutagenic effect of various concentrations of sodium azide on traits of three varieties of tomato was investigated with the aim of improving the quality and quantity of the traits of economic importance. The seeds of three tomato varieties namely: Roma, UC and a Local variety were treated with (0.1mM, 1.0 mM, 2.0 mM and 0.0 mM as control) via pre seasons. The results obtained revealed highly significant difference (P various concentrations of sodium azide on the number of leaves, leaf area, number of fruits, fruit weight, pericarp thickness, number of seeds/fruit and pH of the fruit ju improvement (P≤0.05) was recorded on fruit diameter. More so, significant differences were found in the interactions of the varieties to the mutagenic treatments during the rainy season than the dry season. The interaction showed that all the mutants treated with 0.1mM concentration have the highest response in all the selected traits during rai fruit diameter. Similarly, all the 1.0mM 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. We therefore concl azide concentration improves important quality traits of tomato more especially variety UC as it responds significantly to sodium azide and that, the mutant tomato could be grown both during the rainy and dry seasons.

“…However, these findings were contrary to the work of Zeerak (1990) who observed reduced yield in combined treatments of gamma rays and EMS in Solanum melongena L., and the findings of Pavadai and Dhanvel (2004) in soybeans, and Varshney (1997) in bread wheat due to chemical mutagenesis. Similarly, the increased in 1000 seeds weights of fonio mutants due to colchicine treatments is similar to the findings of Nura et al (2013) who reported similar result among colchicine induced mutants of sesame. CONCLUSION Thus, it is concluded that lower colchicine concentration (0.1mM) played a significant role in improving growth and yield components of fonio and that accession Jiw 1 showed the highest response to colchicine treatment.…”

The effect of colchicine on some growth and yield parameters of fonio (Digitaria exilis) was studied. Seeds of five accessions of fonio (Dinat, Jakah, Jiw 1, Jiw 2 and Nkpowas) were treated with five different colchicine concentrations (0.1mM, 0.5 mM, 1.0 mM, 2.0 mM and soaking with the aim of inducing variability that could be exploited in the improvement of the crop. The treated seeds were sown in a plot in a Completely Randomized Design with three replications in a factorial arrangement. The result obtained revealed highly significant difference (P effects of different concentrations of colchicine on the growth and yield components of fonio. The result showed that colchicine produced taller mutants (79 that are larger in cross sectional area (11.35 number with high number of spikes that are longer and bear high number of seeds/spikes. Similarly the 1000 mutants' seeds weight is higher than concentration dependent, decrease with increase in concentrations. Lower colchicine concentration (0.1 mM) and accession Jiw 1 having highest responses to colchicines treatment was recommended for breeding programs in fonio.

“…In the present study, we found that colchicine induced taller mutants compared with the control treatment. This agrees with the results found by Nura et al (2013); they reported significant increases in plant height of colchicine treated sesame plants. In contrast, the findings of Maluszynski et al (2001) showed a noticeable decrease in the height of rice plant, as a result of induced mutation.…”

ABSTRACT. Six different colchicine concentrations: 0, 400, 800, 1200, 1600, and 2000 ppm, in combination with four soaking time treatments (1, 2, 3, and 4 h), were selected to assess the effects on germination, vegetative growth, and flower yield components in calendula plants. The molecular diversity among the treatments was assessed using ten SRAP marker combinations. Seed soaking in colchicine significantly enhanced both the fresh and the dry shoot and root masses, flowering date, number of flowers per plant, and flower diameter. At 1200-ppm colchicine combined with a 4-h soaking time, a superior effect on seed germination was observed, whereas 800 ppm for 4 h produced the highest number of flowers and the largest flower diameter. The earliest flowering time was found at 800 ppm combined with a short soaking time (1 h), while the 4-h soaking time with 800 ppm, is recommended for growing calendula outdoors, since it enhances flower development. At the molecular level, 752 fragments were successfully amplified
