“…This might be due to the effect of EMS on M 0 seeds, which negatively affected the embryo, germination and this negative effect reflected on the plant growth and fruit formation of M 1 plants (including fruits and formed seeds inside the fruit), which in turn produced bad quality of seeds ( Abdul-Salam, 2007 ). In agreement with our results, previous studies found that the changes in the M 2 generation appeared during the seedling stage in the formation of chlorophyll or slow growth and also affected the growth until maturity ( Pawar et al, 2010 ).…”

This study was conducted to enhance genetic variability in peppers (Capsicum annuum, cv B12) using ethyl methanesulphonate (EMS). Exposure to an EMS concentration of 0.6%, v/v for 12 h was used to mutagenize 2000 seeds for the first generation (M1). It was observed that the growth behaviors including plant height, flowering date, and number of seeds per first fruit were different in the M1 generation than in wild type (WT) plants. In addition one phenotypic mutation (leaf shape and plant architecture) was observed during the M1 generation. During the seedling stage in the M2 generation, the observed changes were in the form of slow growth or chlorophyll defect (e.g., albino, pale green, and yellow seedlings). At maturity, there were three kinds of phenotypic mutations observed in three different families of the mutant population. The first observed change was a plant with yellow leaf color, and the leaves of this mutant plant contained 62.19% less chlorophyll a and 64.06% less chlorophyll b as compared to the wild-type. The second mutation resulted in one dwarf plant with a very short stature (6 cm), compact internodes and the leaves and stem were rough and thick. The third type of mutation occurred in four plants and resulted in the leaves of these plants being very thick and longer than those of WT plants. Furthermore, anatomical observations of the leaf blade section of this mutant plant type contained more xylem and collenchyma tissue in the leaf midrib of the mutant plant than WT. In addition, its leaf blade contained thicker palisade and spongy tissue than the WT.

“…Ginger (Zingiber officinale Rosc.) is valuable plant all over the world as a spice in culinary preparations and for its medicinal properties (Jatoi et al, 2008;Pawar et al, 2010;Sivasothy et al, 2011). Ginger is native to India and South East Asia (Preeti et al, 2008;Abdullah et al, 2010;Tokuhara et al, 2013).…”

Objective: This study aims to characterize and assess the variability within the ginger accessions growing in Burkina Faso for morphometric and agronomic traits in order to identify appropriate strategies for the future breeding program. Methodology and Results: The experiment was conducted with 56 accessions in Randomized Complete Block Design with four replications. Moderate diversity was observed for morphometric and agronomic characters. The linear Pearson's correlations between rhizome yield and rhizome weight per plant were significantly positives with the other characters, except days taken to maturity, which were negatives. Plant height was strongly associated with number of leaves, leaf length and rhizome width. The accessions gathering into two groups is not made according to their origin, but mainly on the basis of the characters such as rhizome yield, rhizome weight per plant, rhizome length, and plant height. Conclusion and application: The ginger germplasm characterization is useful and has made it possible to understand the basic information for development of a scientific strategy for the efficient conservation of ginger. Strong associations between yield components and plant seize are important selection indices of rhizome yield and may be emphasized in the breeding programs for genetic improvement. Moreover, the model of clustering of the accessions can be used as a base for the choice of genotypes with interesting agro-morphological characteristics for the improvement of ginger productivity.

“…It seems that the stronger mutagens reach their saturation point even at lower doses/concentrations in the highly mutable genotypes and further increase in dose/concentrations does not add to the mutation frequency. With an increase in dose/concentrations beyond a point, the strong mutagens become more toxic than the higher doses of relatively weaker mutagens.Higher frequencies of chlorophyll mutations with medium or lower doses of mutagens were reported by Srivastava et al, (1973) and Pawar et al, (2010) in different crops including chick pea.…”

A relative study of frequency and spectrum of chlorophyll mutations induced by mutagens in M2 generation was made with chickpea (Cicer arietinum (L). Variety ‘CO-4’. The treatments include different doses/concentrations of Gamma rays (20, 30, 40, 50 and 60kR) and Ethyl Methane Sulphonate (10, 20, 30, 40 and 50 mM). From the study, the overall frequencies and spectrum of five types of induced chlorophyll mutants Viridis (0.55), Xantha (0.46), Chlorina (0.45), Albina (0.43) and Tigrina (0.35) were observed. The frequency of chlorophyll mutation was increased with increasing concentrations up to a level, beyond it declined in both the mutagens. And the chlorophyll frequency was found in the order of viridis > xantha >chlorina> Albina >tigrina. The chemical mutagen, EMS was found to be more effective in inducing chlorophyll mutations than gamma rays in Chick pea.
