“…In this sense, the commercial cultivars IPR-Curió, Carioca-MG, IAC-Akytã, IAC-Apuã, IAC-Aysó, IAC-Imperador, IAC-Pyatã, IAC-Formoso, IAC-Ybaté and IAC-Tybatã showed the greatest potential for use by Brazilian common bean breeding programs. These cultivars not only fulfilled the minimum requirements of any commercial cultivar [ 114 – 116 ], but also showed high resistance (i.e., score < 3) to the three races evaluated. Molecular evaluation by DAPC, estimated with the significant SNPs from GWAS, showed that these cultivars have the highest number of favorable alleles among the 18 genotypes grouped in terms of resistance pattern ( Fig 5 ).…”

“…Molecular evaluation by DAPC, estimated with the significant SNPs from GWAS, showed that these cultivars have the highest number of favorable alleles among the 18 genotypes grouped in terms of resistance pattern ( Fig 5 ). Among them, the cultivar IAC- Pyatã also showed high resistance to angular leaf spot in a recent study [ 69 ] and had the highest average yield among the 11 other commercial cultivars tested by Pompeu [ 116 ].…”

Genome-wide association mapping reveals race-specific SNP markers associated with anthracnose resistance in carioca common beans

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.

“…flaccumfaciens isolado 2634 um caráter oligogênico (Valentini et al, 2011) e as fontes de resistên-cia para estas doenças serem de origens distintas. Segundo Pompeu (1997), o cultivar IAC-Carioca Aruã resulta de seleção feita em F 4 do cruzamento (10771.122) x [(H5380-41.A156) x (H5380-41.AB136)] e o cultivar IAC-Carioca Pyatã é proveniente de seleções realizadas na geração F 3 do cruzamento DOR41 x (10-3-1.TU1B1-2.10-9-1). Logo, para manter esta variabilidade, a seleção foi praticada em plantas com notas entre 1 e 4.…”

Early selection in segregating common bean plants for resistance to bacterial wiltThe objective of this study were both the estimation of the efficiency of selection in segregating populations of common bean for the resistance to Curtobacterium and also the indication of the best time of the cycle to make the selection of resistant plants. To this end, we used converging crosses between IAC-Carioca Aruã x SCS Guará, IACCarioca Pyatã x IAC-Carioca and SCS Guará x Pérola, originating filial generations (F 1 , F 2 , F 2:3 and F 3:4 ) which were subsequently inoculated with Curtobacterium flaccumfaciens pv. Flaccumfaciens, isolate 2634, and evaluated according to a scale related to the common symptoms of the disease at 20, 40 and 60 days after inoculation. The results showed that the segregating generations of Aruã x Guará, Pyatã x Guará and Pyatã x Pérola had similar behavior in relation to resistance to the Curtobacterium symptoms. The selection is effective for the coming generations of Aruã x Guará and Pyatã x Pérola and the favorable time for distinguishing and selecting reliably segregating plants occurs between 40 and 60 days after inoculation.

Com o objetivo de conhecer o comportamento de linhagens de feijoeiro nas três épocas tradicionais de plantio do Estado de São Paulo, com base em dados de estabilidade fenotípica, dois grupos de experimentos foram instalados nas épocas das águas (setembro-outubro), da seca (janeiro-fevereiro) e de inverno (maio-junho). O grupo 1 (G1), com 47 experimentos, foi formado por 16 linhagens e o controle, cultivar Carioca 80SH, e o grupo 2 (G2), com 44 experimentos, formado por 11 linhagens e pelos controles, cultivares Carioca 80SH e Rosinha G2. O delineamento experimental foi o de blocos ao acaso, com cinco repetições e parcelas constituídas de uma linha de 5 m de comprimento. As análises de variância das produções de grãos foram realizadas por experimento dentro de cada grupo (G1/G2) e conjunta (geral e por época de plantio). Os parâmetros de estabilidade foram estimados pelo método proposto por Cruz et al. (1989). Foram observadas várias linhagens adaptadas em ambientes desfavoráveis em pelo menos uma época de plantio. Diversos genótipos comportaram-se como responsivos ou estáveis nos dois conjuntos de experimentos. Os resultados sugerem a possibilidade de direcionar a recomendação de cultivares, com a escolha das linhagens mais adaptadas e responsivas, específicas para as épocas de cultivo.
