“…Nisha et al 61 also showed that in mung beans grown under WS conditions, there was an increase in root development with the rise in K content. The results are also consistent with the findings of Dhole et al (mung bean) 63 and Sharma et al (moth bean) 64 , who discovered that a decrease in water potential corresponded with a reduction in the number of roots per plant. Additionally, it was shown that increasing the K supply to promote root development resulted in an increased in the root surface area 65 .…”

Uneven rainfall and high temperature cause drought in tropical and subtropical regions which is a major challenge to cultivating summer mung bean. Potassium (K), a major essential nutrient of plants can alleviate water stress (WS) tolerance in plants. A field trial was executed under a rainout shelter with additional K fertilization including recommended K fertilizer (RKF) for relieving the harmful impact of drought in response to water use efficiency (WUE), growth, yield attributes, nutrient content, and yield of mung bean at the Regional Agricultural Research Station, BARI, Ishwardi, Pabna in two successive summer season of 2018 and 2019. Drought-tolerant genotype BMX-08010-2 (G1) and drought-susceptible cultivar BARI Mung-1 (G2) were grown by applying seven K fertilizer levels (KL) using a split-plot design with three replications, where mung bean genotypes were allotted in the main plots, and KL were assigned randomly in the sub-plots. A considerable variation was observed in the measured variables. Depending on the different applied KL and seed yield of mung bean, the water use efficiency (WUE) varied from 4.73 to 8.14 kg ha−1 mm−1. The treatment applying 125% more K with RKF (KL7) under WS gave the maximum WUE (8.14 kg ha−1 mm−1) obtaining a seed yield of 1093.60 kg ha−1. The treatment receiving only RKF under WS (KL2) provided the minimum WUE (4.73 kg ha−1 mm−1) attaining a seed yield of 825.17 kg ha−1. Results showed that various characteristics including nutrients (N, P, K, and S) content in stover and seed, total dry matter (TDM) in different growth stages, leaf area index (LAI), crop growth rate (CGR), root volume (RV), root density (RD), plant height, pod plant−1, pod length, seeds pod−1, seed weight, and seed yield in all pickings increased with increasing K levels, particularly noted with KL7. The highest grain yield (32.52%) was also obtained from KL7 compared to lower K with RKF. Overall, yield varied from 1410.37 kg ha−1 using 281 mm water (KL1; well-watered condition with RKF) to 825.17 kg ha−1 using 175 mm water (KL2). The results exhibited that the application of additional K improves the performance of all traits under WS conditions. Therefore, mung beans cultivating under WS requires additional K to diminish the negative effect of drought, and adequate use of K contributes to accomplishing sustainable productivity.

“…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.

“…High heritability and GVC values were obtained only in the characters of shoot and tillers weights. The value of heritability due to gamma irradiation was also reported in other studies such as Vigna ,mungo (Sri Devi, 2012), lentils (Laskar & Khan, 2017), sorghum (Anand & Kajjidoni, 2014), chick-pea (Amri-Tiliouine et al, 2018), mungbean (Vigna radiata) (Dhole & Reddy, 2018), pinger millet (Umeshkumar et al, 2015), and rice (Islam et al, 2015).…”

Mutation breeding using gamma irradiation is one of the alternative ways to increase the variability and productivity of Guinea grass (Panicum maximum cv Purple guinea). The aimed of the study was to determine the dosage of gamma irradiation and morphological characters for highyielding of the putative mutant of guinea grass. The Guinea grass seeds was irradiated by gammaray. The treatment was 8 doses of gamma irradiation and control (non-irradiated). The treatment was arranged in a randomized complete block design (RCBD) with 3 replications. The study was conducted for 3 generations, which were mutants 1 (M1), mutant 1 vegetative 1 (M1V1), and mutant 1 vegetative 2 (M1V2). The results showed that the gamma irradiation dose affected variables observed. The variables affected in M1 were fresh and dry weights of shoot, the number of tillers, and the length of the leaves. Whereas in the populations of M1V1 and M1V2, almost all characters were influenced by gamma irradiation, except stem diameter, length of internode, and leaf length. Gamma irradiation doses of 175 x 2 Gy, 250 Gy and 350 Gy in M1V1 and 100 x 2 Gy, 150x2 Gy and 175 x 2 Gy in M1V2 produced the high number of tillers, fresh and dry shoot weights. Heritability value and GCV of number of tillers, fresh and dry weight of shoot were high for M1V1 and M1V2 populations. These results indicated that gamma-ray irradiation can be applied to increase productivity and genetic variability of Guinea grass. The highest forage production was obtained at a dose of 100 x 2 Gy, which was 625 g/plant.
