“…Tulmann Neto et al (2011) reported that the chlorophyll mutants were used in evaluation of the genetic effects and sensitivity of various mutagens on crops. These results are in agreement with Goyal and Khan (2010) whose studies indicated that the incidence of chlorophyll mutants were higher with increased Gy doses in earlier selection generations.…”

“…These cultivars were released across 59 countries worldwide, mainly in the continental Asia (1,142 cultivars), Europe (847), and North America (160) (Maluszynski, 2001; Maluszynski et al, 2009). Studies indicate that induced mutagenesis has successfully modified several plant traits such as plant height, maturity, seed shattering resistance, disease resistance, oil quality and quantity, malting quality, size and quality of starch granules of cowpea (Goyal and Khan, 2010; Singh et al, 2013). …”

Cowpea (Vigna unguiculata [L.] Walp.) yields are considerably low in Namibia due to lack of improved varieties and biotic and abiotic stresses, notably, recurrent drought. Thus, genetic improvement in cowpea aims to develop cultivars with improved grain yield and tolerance to abiotic and biotic stress factors. The objective of this study was to identify agronomically desirable cowpea genotypes after mutagenesis using gamma irradiation. Seeds of three traditional cowpea varieties widely grown in Namibia including Nakare (IT81D-985), Shindimba (IT89KD-245-1), and Bira (IT87D-453-2) were gamma irradiated with varied doses and desirable mutants were selected from M2 through M6 generations. Substantial genetic variability was detected among cowpea genotypes after mutagenesis across generations including in flowering ability, maturity, flower and seed colors and grain yields. Ten phenotypically and agronomically stable novel mutants were isolated at the M6 each from the genetic background of the above three varieties. The selected promising mutants’ lines are recommended for adaptability and stability tests across representative agro-ecologies for large-scale production or breeding in Namibia or similar environments. The novel cowpea genotypes selected through the study are valuable genetic resources for genetic enhancement and breeding.

“…Genetic variation among genotypes and relationship between major yield contributing traits/characters is of vital importance to breeding programmes that aim to produce important cultivars [1]. Use of mutagens for inducing genetic variation is well established [2,3]. Therefore the present investigation was undertaken to understand the response of different types of moth bean varieties to more than one type and treatment of chemical mutagens and evaluate the mutagenic progenies in respect to yield and yield attributes in M 2 and M 3 generation.…”

Induced biological damage, polygenic variability and comparative mutagenic effectiveness and efficiency of EMS, MMS, SA and HA were studied in four varieties of moth bean, namely, RMO-40, RMO-257, Jwala and CZM-1. Gradual reduction in germination, pollen fertility and survival percentage was observed with increased doses of mutagens. The frequency of chlorophyll mutants was less and were of two types i.e., albino and xantha in which albino type was less frequent. The spectrum of morphological mutations was defined in ten different classes (revertant, bushy, bifurcated stem, bolted, sterile, miniature, branched, increased peduncle length, spreading habit, and increased primary branches). The most effective treatment appeared to be 0.05% MMS, whereas least were 50mM hydroxylamine. The effectiveness of various mutagen treatments was generally higher on RMO-40 and lower on CZM-1. The effectiveness of treatments was decreased in the order of MMS > SA> EMS > HA. The highest mutagenic efficiency was observed with 1.0 mM Sodium azide in the Mothbean variety RMO-40. On the basis of estimates of pooled over genotypes and doses with in a mutagen, SA was the most efficient mutagen followed by MMS, EMS and HA. In M 3 generation, 15 progenies showed significantly superior seed yield per plant with higher magnitude of yield contributing traits then the best check, RMO-225. Branches per plant and pods per plant exhibited high genetic variability in M 3 generation.

“…Kodym and Afza ( 2003 ) suggested that if no relevant data on appropriate doses of mutagens are available, a preliminary experiment with different doses must be conducted to determine the mutagenic effectiveness and effi ciency. It is not necessary that an effective mutagen shall be an effi cient one also ( Koli and Ramkrishna 2002 ;Gaikwad and Kothekar 2004 ;Goyal and Khan 2010 ). Both of these though are two different properties, but the usefulness of any mutagen in plant breeding program depends on both of them.…”
