“…The higher efficiencies of the lower and moderate concentrations of mutagens were clearly due to the lower biological damage (seedling injury, pollen sterility and meiotic abnormalities) which increased with increase in the strength of the mutagen treatments. Similar observations of higher effectiveness and efficiency at the lower and moderate concentrations of mutagens were also made in Lathyrus sativus [23], Pisum sativum [24], Glycine max [25] and Vigna radiata [26].…”

Abstract. In mutation breeding, mutagenic effectiveness and efficiency are the base parameters to predict the mutagenic potency of any mutagen. Studies on mutagenic effectiveness and mutagenic efficiency of physical mutagen (gamma rays) and chemical mutagen (hydrazine hydrates; HZ) on two cultivars of lentil (Lens culinaris Medik.), viz. DPL 62 (macrosperma) and Pant L 406 (microsperma) have been reported. Dry and healthy seeds were treated with four doses of each gamma rays (100-400 Gy), HZ (0.1-0.4 %) and their combinations. Frequencies of the induced agro-morphological variations into different phenotypic categories were estimated in M 2 population that resulted into identification and isolation of wide range of mutants with altered phenotypes. Data on effectiveness and efficiency of various mutagenic treatments calculated on the basis of the frequency of chlorophyll mutations, which showed effectiveness and efficiency were higher at the moderate doses of gamma rays and HZ, while in case of combination treatments; lower doses were most effective and efficient with few inter-varietal exceptions. Phenotyping of the mutants revealed that growth habits was the most sensitive category to which most of the mutant belongs, followed by leaf and flower/pod/seed in both the cultivars studied. Overall, the screened and isolated mutants with economically important agronomic traits can be further propagated in the subsequent generation for development of elite lentil mutant cultivars.

“…Similar results of high frequency and broad spectrum of induced morphological mutants by chemical mutagens were also reported in Vigna mungo (Arulbalachandran and Mullainathan, 2009;Goyal and Khan, 2010), Vicia faba L. (Laskar and Khan, 2014;Laskar et al, 2015), Lens culinaris (Tyagi and Gupta, 1991;Tripathi and Dubey, 1992;Solanki and Sharma, 1999;Amin et al, 2015), Cicer arietinum (Khan et al, 2004), Glycine max (Khan and Tyagi, 2010) and Cicer arietinum (Wani, 2011). Macromutations affecting growth habit, flower color and plant type have been reported in chickpea earlier (Ahmad and Godward, 1993;Kharkwal, 1999;Gaur and Gour, 2001;Khan et al, 2004;Wani, 2011).…”

A B S T R A C TIn the present scenario of variable natural environment and sky-high population, sustainable boost in the agricultural productivity is the utmost priority. Induce mutagenesis generates noble genetic combination without affecting the overall genomic makeup of crop, thus, providing essential genetic variation for any crop improvement programme. The present study has been carried out to investigate the comparative mutagenicity of gamma rays and HZ on chickpea (Cicer arietinum L.) genotype (avrodhi) at M 2 generation developed from seeds of treated M 1 plants population. The assessment on phenotypic expression for the studied qualitative and quantitative traits showed considerable deviations in all the treatments and significant positive shift in 0.01 and 0.02% doses compared to control while 0.04% proved to be most mutagenic with highest significant negative deviation. A broad spectrum and frequency of macro mutations were induced affecting all plant parts and different morphological variants were screened and isolated on the basis of economic importance from the treated populations. Economically important mutations like branching pattern, stem structure, plant height, dwarf and bushy growth habit, foliage type, flowering behavior and maturity were identified and the frequency of the variants were found to be more in 0.03% doses. Explicitly, HZ doses provided greater deviations in both directions in the quantitative phenotypic characters studied while frequencies of distinct morphological mutants were more in gamma rays. The induced elite phenotypes (blue flowered, double flowered, pigmented leaf, bushy and early mutants), having strong correlation with agronomic traits, will definitely be helpful in selection of improved mutants in subsequent generations.

“…Davis et al (1985) isolated a chickpea mutant with enlarged leaves, pods, seeds and flowers after gamma irradiation of seeds. Wani (2007) and Khan and Tyagi (2010) have also reported gigas mutants in both mungbean and soybean. The highest frequency of morphological mutants was noted in the HZ treated populations (5.19%) and the lowest was with SA (1.39%) while MMS treatments (3.89%) were intermediate (Table 1).…”

Seeds of two varieties (PUSA-212 and BG-256) of chickpea (Cicer arietinum L.) were treated with 0.03% concentration of hydrazine hydrate (HZ), methylmethane sulphonate (MMS) and sodium azide (SA) for 6 h. The M 2 generation was grown from single plant M 1 progeny seeds. Five morphological mutants (dwarf, bushy, one sided branch, narrow leaf and gigas) were isolated in M 2 generation. Some of these mutants may be directly used in selection whereas some are useful in combination breeding programs.
