Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli, is one of the most prevalent diseases in the common bean crop (Phaseolus vulgaris). However, there is little information regarding the genetics of reaction to this disease. Thus, the aims of this study were to estimate genetic parameters, identify quantitative trait loci (QTLs) associated with reaction to Fusarium wilt, and validate the markers identified. A total of 165 progenies of the population BRS FP403 × BRS Horizonte were evaluated. Evaluation was made in 2016 and 2017 in field trials in an area infested with the pathogen in Santo Antônio de Goiás, Brazil. Genotyping of single nucleotide polymorphism and SilicoDArT, where DArT is Diversity Arrays Technology, markers using the DArTseq technology was performed in the F2 generation. Analyses of the phenotypic data indicated the presence of variability among the progenies and the possibility of success from selection, with high estimates of heritability (90%) and gain from selection (37%). A genetic map was obtained with 702 markers and spanned 3069 cM. Five QTLs associated with reaction to Fusarium wilt were identified on five chromosomes. There was interaction between the QTLs and years. Through joint analysis, four QTLs were identified on chromosomes Pv01, Pv02, Pv03, and Pv04, explaining 5.8%–40.5% of the variation. The QTL FOP2.3403H explained 40.5% of phenotypic variation and was stable over the 2 years. From this QTL, two hydrolysis probes were developed for genotyping in a panel of lines for validation. Selection efficiency was over 92%, indicating considerable potential for use in marker-assisted selection.

The world population is expected to be larger and wealthier over the next few decades and will require more animal products, such as milk and beef. Tropical regions have great potential to meet this growing global demand, where pasturelands play a major role in supporting increased animal production. Better forage is required in consonance with improved sustainability as the planted area should not increase and larger areas cultivated with one or a few forage species should be avoided. Although, conventional tropical forage breeding has successfully released well-adapted and high-yielding cultivars over the last few decades, genetic gains from these programs have been low in view of the growing food demand worldwide. To guarantee their future impact on livestock production, breeding programs should leverage genotyping, phenotyping, and envirotyping strategies to increase genetic gains. Genomic selection (GS) and genomewide association studies play a primary role in this process, with the advantage of increasing genetic gain due to greater selection accuracy, reduced cycle time, and increased number of individuals that can be evaluated. This strategy provides solutions to bottlenecks faced by conventional breeding methods, including long breeding cycles and difficulties to evaluate complex traits. Initial results from implementing GS in tropical forage grasses (TFGs) are promising with notable improvements over phenotypic selection alone. However, the practical impact of GS in TFG breeding programs remains unclear. The development of appropriately sized training populations is essential for the evaluation and validation of selection markers based on estimated breeding values. Large panels of single-nucleotide polymorphism markers in different tropical forage species are required for multiple application targets at a reduced cost. In this context, this review highlights the current challenges, achievements, availability, and development of genomic resources and statistical methods for the implementation of GS in TFGs. Additionally, the prediction accuracies from recent experiments and the potential to harness diversity from genebanks are discussed. Although, GS in TFGs is still incipient, the advances in genomic tools and statistical models will speed up its implementation in the foreseeable future. All TFG breeding programs should be prepared for these changes.
