“…The chemical mutagens induced more variability in LH90-54, whereas the physical mutagen (gamma rays) was found more effective in LH89-48. Similar observations with regard to the mutagens and mutagenic treatments have been reported earlier in lentil (Sarker and Sharma, 1987), chickpea (Pathania and Sood, 2006), green gram (Singh and Rao, 2007) and soybean (Kartika and Subba Lakshmi, 2006;Khan and Tyagi, 2009). …”

“…LH89-48. The incidence of higher mutation induction by alkylating agents, particularly EMS, is due to their higher alkylation ability affecting gene molecule directly in lentil (Sarker and Sharma, 1987;Sharma, 1999, 2001), Vicia faba (Bhat et al, 2007), soybean (Kartika and Subba Lakshmi, 2006;Khan and Tyagi, 2009), chickpea (Khan et al, 2005;Pathania and Sood, 2006) and green gram (Velu et al, 2008). EMS has also been reported to induce higher frequency of mutations than SA in lentil (Solanki and Phogat, 2005) and chickpea (Khan et al, 2005).…”

Variable varietal responses to different mutagens and treatments for induction of mutations have been reported in chickpea (Pathania and Sood, 2006), green gram (Singh and Rao, 2007) and soybean (Kartika and Subba Lakshmi, 2006;Khan and Tyagi, 2009). The large seeded varieties are comparatively found to be more mutable than the small seeded varieties in chickpea (Pathania and Sood, 2006) and Vicia faba (Bhat et al, 2007).…”

Three mutagenised populations each of gamma rays, sodium azide (SA) and ethyl methane sulphonate (EMS) showed increased amount of variability over control for different polygenic traits in both macrosperma (LH90-54) and microsperma (LH89-48) lentil cultivars in M 2 generation. Among the mutagens tested, EMS induced maximum variability for all the traits, followed by gamma rays and SA in both the cultivars. The highest frequencies of mutated [M 2 progenies with higher coefficient of variation (CV) than the corresponding highest CV in control for any of the traits] and promising progenies [M 2 mutated progenies where mean shifted in the desired direction] were induced by different mutagens in the order: EMS > gamma rays > SA in both the cultivars (LH90-54 > LH89-48). In LH 90-54, promising progenies with multiple traits were induced with the highest frequency by SA, followed by EMS and gamma rays, whereas in LH89-48, they were induced with the highest frequency by SA, followed by gamma rays and EMS. Invariably, the medium dose of mutagens (0.08% SA, 0.40% EMS and 10 kR gamma rays) induced maximum variability (CV, %), resulting in the highest number of promising progenies for all the polygenic traits.

“…Similarly, Paul and Singh (2002) reported 0.8% of chlorophyll mutants in lentils using 100 and 150 Gy. The frequency of chlorophyll mutation was observed as 1.21% and 2.42% in two varieties of soybean at 150 Gy (Khan and Tyagi, 2009). In cluster bean, Bhosle and Kothekar (2010) recorded 1.66%, 2.21% and 2.61% of chlorophyll mutations at 50, 100 and 150 Gy, respectively.…”

Aim : Methodology :Results : Interpretation :Narrow genetic base and limited genetic diversity are the major research constraints that affect the efficacy of class breeding methods in lentil. In order to circumvent these conditions, mutation breeding techniques were successfully employed in many studies. The present study was conducted to find the LD dose of gamma rays in lentil cultivar, Idlib-3 and also to develop and characterize M population for economically important quantitative traits.

“…Numerous authors have so for reported the incidence of different types of chlorophyll mutations such as albina, xantha, chlorina, viridis, virescent, tigrina, etc. in M 2 generation following mutagenic treatments (Waghmare 2001;Toker and Cagirgan 2004;Yamaguchi et al 2006;Khan and Tyagi 2009;Arulbalachandran and Mullainathan 2009;Wani et al 2011b;Girija and Dhanavel 2013a). Chemical mutagens induce higher frequency of chlorophyll mutations as compared to radiations in chickpea (Kharkwal 1998b) and grasspea (Waghmare and Mehra 2001).…”

Improvement of Crops in the Era of Climatic Changes

Breeding of pulses, especially chickpea, by exploiting genetic diversity using conventional methods has been practiced in the past. Nevertheless, these methods at present are inadequate for making any significant breakthrough to handle the world's ever-increasing food demand. In this bizarre scenario, induced mutations have emerged as big relief, and are largely exploited for developing improved high-yielding crop varieties and for discovering desired genes that control important agronomical traits. Gene mutation, leading to the quality advancement of well-adapted existing varieties, has been the pedestal for germplasm improvement. Pulses are more prone to biotic and abiotic stresses as compared to cereals. As a result, there is a serious need to develop such varieties having high resistance to the above-mentioned stresses. During the past eight and a half decades, around 3,139 improved crop varieties have been released globally derived either as direct mutants or from their progenies (http://mvgs.iaea.org). Vast numbers of these varieties like cereals, pulses, oil crops, root and tuber crops and ornamentals have been released in developing countries for cultivation, including India, resulting in massive economic impact. Lately, mutagenesis has received an immense impel for its use in a newfangled promising technique known as targeting induced local lesions in genomes. With the unfolding of novel biological fields such as genomics, functional genomics, bioinformatics and the emergence of other technologies based on these sciences, there has been an increased surge in induced mutations within the scientific community. The knowledge of functional and basic genetics of model legume crops will benefit chickpea breeders to comprehend that marker-assisted selection has great potential to develop biotic and abiotic stress-resistant varieties. The basic understanding of genes, which direct major agronomical traits, is essential for plant breeders to frame apposite approaches and execute them in breeding programmes for promising results. In this era, with growing human population, hunger ghosts are haunting millions of people all around. Under these circumstances, the salvaging step lies in tailoring better crop varieties embedded with superior proteins, minerals and high yield. Mutagenic agents, physical as well as chemical, are used to induce mutations and generate variations from which desired mutants may be selected. However, basic information vis-à-vis effectiveness of various mutagens and their possible role in generating polygenic variability is meagre among pulses in general and chickpea in particular. Hence, the present review condenses various facets of contemporary knowledge for pulse crop varietal improvement, particularly chickpea, through induced mutagenesis with special thrust on qualitative as well as yieldattributing traits.
