“…Plants with scores from 1.0 to 3.0 were considered resistant, from 3.1 to 6.0 were considered moderately resistant, and from 6.1 to 9.0 were considered susceptible. In all trials, the cultivar IAC-1850 was used as a resistance check, due to its high resistance to all races [ 74 ], and Rosinha G2 was used as a susceptible check [ 17 ].…”

Brazil is the largest consumer of dry edible beans (Phaseolus vulgaris L.) in the world, 70% of consumption is of the carioca variety. Although the variety has high yield, it is susceptible to several diseases, among them, anthracnose (ANT) can lead to losses of up to 100% of production. The most effective strategy to overcome ANT, a disease caused by the fungus Colletotrichum lindemuthianum, is the development of resistant cultivars. For that reason, the selection of carioca genotypes resistant to multiple ANT races and the identification of loci/markers associated with genetic resistance are extremely important for the genetic breeding process. Using a carioca diversity panel (CDP) with 125 genotypes and genotyped by BeadChip BARCBean6K_3 and a carioca segregating population AM (AND-277 × IAC-Milênio) genotyped by sequencing (GBS). Multiple interval mapping (MIM) and genome-wide association studies (GWAS) were used as mapping tools for the resistance genes to the major ANT physiological races present in the country. In general, 14 single nucleotide polymorphisms (SNPs) showed high significance for resistance by GWAS, and loci associated with multiple races were also identified, as the Co-3 locus. The SNPs ss715642306 and ss715649427 in linkage disequilibrium (LD) at the beginning of chromosome Pv04 were associated with all the races used, and 16 genes known to be related to plant immunity were identified in this region. Using the resistant cultivars and the markers associated with significant quantitative resistance loci (QRL), discriminant analysis of principal components (DAPC) was performed considering the allelic contribution to resistance. Through the DAPC clustering, cultivar sources with high potential for durable anthracnose resistance were recommended. The MIM confirmed the presence of the Co-14 locus in the AND-277 cultivar which revealed that it was the only one associated with resistance to ANT race 81. Three other loci were associated with race 81 on chromosomes Pv03, Pv10, and Pv11. This is the first study to identify new resistance loci in the AND-277 cultivar. Finally, the same Co-14 locus was also significant for the CDP at the end of Pv01. The new SNPs identified, especially those associated with more than one race, present great potential for use in marker-assisted and early selection of inbred lines.

“…The accessions were genotyped by high-throughput genotyping technologies using the Illumina BeadChip BARC-Bean6K_3 [51]. The CDP was validated for GWAS by Almeida et al [9] and consists of the main commercial cultivars of carioca bean in Brazil, from the first cultivar (i.e., 'Carioca comum') released in 1971 [52] to more modern cultivars, such as IAC-1850, released in 2019 [53]. The set also includes genotypes with contrasting seed coat darkening rates identified in previous studies, with the RD cultivars BRS-Cometa, BRS-Estilo, BRS-Pérola, BRS-Pontal, BRS-Requinte, IAC-Alvorada, and BRS-Majestoso [10,16,17,23,28,29,32] and the SD cultivars BRS-Madrepérola, ANFC-9, Branquinho, and TAA-Dama [28,32,33].…”

Genome-wide association mapping reveals new loci associated with light-colored seed coat at harvest and slow darkening in carioca beans

Background Common bean (Phaseolus vulgaris L.) is a legume whose grain can be stored for months, a common practice among Brazilian growers. Over time, seed coats become darker and harder to cook, traits that are undesirable to consumers, who associate darker-colored beans with greater age. Like commercial pinto and cranberry bean varieties, carioca beans that have darker seeds at harvest time and after storage are subject to decreased market values. Results The goal of our study was to identify the genetic control associated with lightness of seed coat color at harvest (HL) and with tolerance to post-harvest seed coat darkening (PHD) by a genome-wide association study. For that purpose, a carioca diversity panel previously validated for association mapping studies was used with 138 genotypes and 1,516 high-quality SNPs. The panel was evaluated in two environments using a colorimeter and the CIELAB scale. Shelf storage for 30 days had the most expressive results and the L* (luminosity) parameter led to the greatest discrimination of genotypes. Three QTL were identified for HL, two on chromosome Pv04 and one on Pv10. Regarding PHD, results showed that genetic control differs for L* after 30 days and for the ΔL* (final L*—initial L*); only ΔL* was able to properly express the PHD trait. Four phenotypic classes were proposed, and five QTL were identified through six significant SNPs. Conclusions Lightness of seed coat color at harvest showed an oligogenic inheritance corroborated by moderate broad-sense heritability and high genotypic correlation among the experiments. Only three QTL were significant for this trait – two were mapped on Pv04 and one on Pv10. Considering the ΔL, six QTL were mapped on four different chromosomes for PHD. The same HL QTL at the beginning of Pv10 was also associated with ΔL* and could be used as a tool in marker-assisted selection. Several candidate genes were identified and may be useful to accelerate the genetic breeding process.

“…Smallholder's farms dominate the Brazilian production of common beans (about 67%), but there is a tendency to increase the participation of medium and large farmers, mainly in the Cerrado region (irrigated winter cultivation) (Ganascini et al, 2019). According to Carbonell et al (2019), winter cultivation is characterized by the intensive use of synthetic inputs, like chemical fertilizers that provide significant increases in grain yield, however, it also increases production costs.…”

Multifunctional microorganisms (MM) are able of colonizing root system and shoots and then, provide beneficial effects to the plants. Thus, the objective of this study was test whether multifunctional microorganisms affect gas exchange, macronutrient content, yield components and bean grain yield. A completely randomized design with twenty-six treatments and three replications was used under controlled conditions. Treatments consisted of the application of MM and its combinations in pairs, with nine rhizobacteria isolates BRM 32109, BRM 32110 and 1301 (Bacillus sp.), BRM 32111 and BRM 32112 (Pseudomonas sp.), BRM 32113 (Burkholderia sp.), BRM 32114 (Serratia sp.), 1381 (Azospirillum sp.) and Ab-V5 (Azospirillum brasiliense), an edaphic fungal isolate T-26 (Trichoderma koningiopsis), and a control (without MM). The isolates Ab-V5 and BRM 32112, in addition to the combinations BRM 32114 + T-26, 1301 + BRM 32110 and BRM 32114 + BRM 32110 were the highlights treatments, since they provided increases in gas exchange, in the content of macronutrients and in the agronomic performance.
