“…Decrease in M 1 pooled mean in clusters with higher mutagenic dose clearly revealed more of biological damage in higher doses of mutagenic treatment. The results was in conformity with the earlier findings of Singh and Rao (2007) and Mishra and Singh (2013) in green gram and Patial et al, (2015) in rice bean.…”

“…The possible reason for the reduction in growth and plant characteristics could be due to magnitude of biological damage (seedling injury, seedling height, sterility etc.) caused by mutagens at cellular level (Patial et al, 2015). The reduction in germination per cent in the treated population in rice bean could be attributed to the disturbance in the enzyme system involved in the repair mechanism or due to the toxic substances produced in the treated cells (Patial et al, 2015).…”

Reduction in plant height, length of pod and number of seeds per pod in M 1 plants of other pulse crops have been reported earlier by many researchers (Sevalm et al, 2010;Kumar et al, 2010 andOlasupo et al, 2016 in cowpea;Kalusinh, 2015 in green gram;Lavanya et al, 2017 in black gram).…”

“…NC, NPC, and NPP exhibited a significant and positive association with grain yield for the cultivars ADT 3, Co 6, and TU 17-9, demonstrating that selection through these traits can be used for identifying improved yield mutants [37,38]. Our result corroborated findings in rice bean [39], mungbean [40], and cowpea [41]. M 4 mutant populations of each cultivar formed three clusters.…”

Development of Novel Blackgram (Vigna mungo (L.) Hepper) Mutants and Deciphering Genotype × Environment Interaction for Yield-Related Traits of Mutants

Blackgram (Vigna mungo (L.) Hepper) yields are noticeably poor due to a shortage of improved varieties and an aggravated narrow genetic base. An attempt was made to isolate novel blackgram mutants by selecting for yield-related traits derived through gamma irradiation and testing the mutant genotype’s stability across the different environments. The irradiated blackgram populations M1-M5 were established in the background of cultivars ADT 3, Co 6, and TU 17-9. Desirable mutants were selected from M3 to M5 generations. It was observed in M2 and M3 that gamma rays showed higher mutagenic efficacy and generated good inherited variance for the yield-related traits. M4 established three divergent groups in each blackgram cultivar revealed by clustering analysis. The number of pods per plant, number of clusters per plant, and number of pods per cluster showed a strong direct association with single plant yield and could be considered as selection traits. G × E interactions were higher than the variation due to genotype for single plant yield. Limited environmental interaction was observed for the genotypes G24, G16, G36, G30, and G17, as revealed by AMMI, and the genotypes G18 and G29, as revealed by GGE. GGE biplot revealed the environment-specific genotypes G13 for E1 (Aduthurai), G7 for E2 (Kattuthottam), and G34 for E3 (Vamban) and also portrayed the highly discriminating (E3) and representative (E2) environments. Selected novel blackgram genotypes from this research are useful genetic stocks for genetic improvement and breeding.

The better understanding of selecting an effective and efficient mutagen may provide better chances to induce high frequency of desirable mutations in any crop breeding program. Present study was carried out with the eggplant (Solanum melongena) variety Pusa Uttam to test the mutagenic effectiveness and efficiency of gamma ray, methyl methane sulphonate (MMS), dimethylsulphate (DMS) and diethyl sulphate (DES) to induce maximum macro-mutations which could eventually be exploited in future as viable and economically important traits. Mutagenic effectiveness and efficiency were calculated as per the standard formulae. In general, the results indicated that mutagenic effectiveness and efficiency decreased with increase in mutagenic treatments. Moreover, the lower or intermediate treatments of gamma rays as well as the alkylating agents were found more effective and efficient in creating maximum mutations with less biological damage. The order of mutagenic effectiveness was MMS>DMS>DES>gamma ray. The order of mutagenic efficiency with regard to inhibition in germination (Mp/I) was same as the effectiveness, while, the orders of efficiency with regard to pollen sterility (Mp/S) was DMS>DES>MMS>gamma ray. The alkylating agents were found to be more potent than gamma rays in effectively and efficiently widening the genetic base of variability in eggplant and provided greater chances for selecting different desirable characters in future breeding program.
