“…Mung bean plants were grown using Leonard jars ( Vincent, 1970 ) maintained in a greenhouse located in Seropédica, RJ, Brazil. An experiment was conducted in a factorial scheme (soil × genotype) and a randomized block design with three replications: 10 soil samples from different regions of Brazil and two mung bean genotypes, MGS Esmeralda ( Vieira et al, 2008 ) and the Camaleão cultivars. Ten soil samples were collected in agricultural areas located in the Midwest and Southeast Brazilian regions, previously cultivated with mung bean and/or other legumes ( Figure 1 and Table 1 ).…”

“…Two mung bean cultivars registered at the Brazilian Ministry of Agriculture, Livestock and Supply were used: MGS Esmeralda (registry 22096) and Camaleão (registry 36829). MGS Esmeralda was developed by Asian Vegetable Research and Development Center (Shanhua, Taiwan), as a result of crossing between the lines VC 1973A and VC 2768A ( Vieira et al, 2008 ). Camaleão is a recently released cultivar in 2018, developed by Minas Gerais Agricultural Research Agency, EPAMIG.…”

Bradyrhizobium as the Only Rhizobial Inhabitant of Mung Bean (Vigna radiata) Nodules in Tropical Soils: A Strategy Based on Microbiome for Improving Biological Nitrogen Fixation Using Bio-Products

et al. 2021

The mung bean has a great potential under tropical conditions given its high content of grain protein. Additionally, its ability to benefit from biological nitrogen fixation (BNF) through association with native rhizobia inhabiting nodule microbiome provides most of the nitrogen independence on fertilizers. Soil microbial communities which are influenced by biogeographical factors and soil properties, represent a source of rhizobacteria capable of stimulating plant growth. The objective of this study is to support selection of beneficial bacteria that form positive interactions with mung bean plants cultivated in tropical soils, as part of a seed inoculation program for increasing grain yield based on the BNF and other mechanisms. Two mung bean genotypes (Camaleão and Esmeralda) were cultivated in 10 soil samples. Nodule microbiome was characterized by next-generation sequencing using Illumina MiSeq 16S rRNA. More than 99% of nodule sequences showed similarity with Bradyrhizobium genus, the only rhizobial present in nodules in our study. Higher bacterial diversity of soil samples collected in agribusiness areas (MW_MT-I, II or III) was associated with Esmeralda genotype, while an organic agroecosystem soil sample (SE_RJ-V) showed the highest bacterial diversity independent of genotype. Furthermore, OTUs close to Bradyrhizobium elkanii have dominated in all soil samples, except in the sample from the organic agroecosystem, where just B. japonicum was present. Bacterial community of mung bean nodules is mainly influenced by soil pH, K, Ca, and P. Besides a difference on nodule colonization by OTU sequences close to the Pseudomonas genus regarding the two genotypes was detected too. Although representing a small rate, around 0.1% of the total, Pseudomonas OTUs were only retrieved from nodules of Esmeralda genotype, suggesting a different trait regarding specificity between macro- and micro-symbionts. The microbiome analysis will guide the next steps in the development of an inoculant for mung bean aiming to promote plant growth and grain yield, composed either by an efficient Bradyrhizobium strain on its own or co-inoculated with a Pseudomonas strain. Considering the results achieved, the assessment of microbial ecology parameters is a potent coadjuvant capable to accelerate the inoculant development process and to improve the benefits to the crop by soil microorganisms.

“…The mass of 100 grains differed among genotypes (P < 0.01) in all eight environments (Table 2), ranging from 4.98 g (Sorriso2020NF) to 6.38 g (Sinop2019WF). On average, grains of the evaluated genotypes were within the standard of commercial cultivars (Vieira et al, 2002;Vieira et al, 2008;Khattak et al, 2021;Kim et al, 2020;). Regarding the VC scores, there were significant differences (P < 0.05) among the tested genotypes in Sinop2020WF and in all four Sorriso environments (Table 2).…”

“…One of the major problems faced by mungbean farmers in Mato Grosso is the limited number of cultivars available. Registered cultivars are recommended for other regions of the country, such as the state of Minas Gerais (Vieira et al, 2002;Vieira et al, 2008;Vieira et al, 2022), but they are not commonly used in Mato Grosso. This, allied to the lack of information on management practices, led to farmers having uneven grains and lower harvest yield than desired.…”

Evaluation of genotype x environment interactions is essential in plant breeding aimed at adapting crops to new settings. Considering the need for research on the adaptation of mungbean to grain-production regions of Brazil, this study evaluated the agronomic performance, adaptability, and stability of mungbean production in the mid-north of Mato Grosso using different genotypes. Two experiments (with and without fertilizer application) were carried out in Sorriso and Sinop in 2019 and 2020, totaling eight environments. The treatments were 10 mungbean lines and the control cultivar BRSMG Camaleão. In general, significant differences among the treatments were observed in the yield, mass of 100 grains, and value for cultivation. The genotype x environment interactions were significant for yield. On average, the yield was in the range of 734-1305 kg ha-1, the mass of 100 grains was 4.63-6.56 g, and the value for cultivation was 2.08-3.56. Genotypes BRA-08654-1, BRA-000027, BRA-084654-2, and BG3 combined high average yield and mass of 100 grains. These genotypes also showed good adaptability for cultivation in the mid-north of Mato Grosso. The yellow seed-coated genotype BRA-084689 also showed good agronomic performance and adaptability. Genotypes BRA-08654-1, BRA-000027, BRA-084654-2, BRA-084689, and BG3 are promising for further experiments evaluating the value for cultivation and use, the final breeding stage consisting of tests at a national level.

“…It has medium-sized, shiny, green seeds (43 to 51 g for 1000-seed weight) and yielded 12% more than 'Ouro Verde'. 'MGS Esmeralda' was released in 2007 (Vieira et al 2008); it has medium-sized to large, dull, green seeds (59 to 68 g for 1000 seed weight) and yielded 13% more than 'Ouro Verde MG 2'. Currently, emphasis has shifted to grains for export.…”
