The use of several strategies for estimating genetic parameters in passion fruit (Passiflora spp.) segregating populations has important implications for understanding the nature of variances, especially the traits of resistance to collar rot. The objective of this study was to estimate genetic parameters and predict gains with the selection of genotypes resistant to collar rot in a population of interspecific passion fruit hybrids. For the analysis of restricted maximum likelihood/ best linear unbiased prediction (REML/BLUP), 40 interspecific hybrids obtained by crossing resistant wild species with Passiflora edulis Sims genotypes were analyzed. The Comstock and Robinson Design II methodology used two male parents (P. nitida Kunth and P. quadrangularis L.) and two female parents of P. edulis. The evaluations took place for 33 d and 10 variables of resistance to collar rot were characterized. The expression of most variables was due to the genetic effect. Dominance effects predominated. High estimates of heritability based on clone average and selective accuracy were observed, which provides favorable gains in reducing the severity of collar rot by selecting the genotypes 115-5,

Furthermore, the resistance to ASB can be inherited qualitatively or quantitatively depending of the genotypes used, plant organ evaluated, environment, virulence of the isolate, and/or methodology of the screening used ( Olaya et al., 1996 ; Miklas et al., 1998b ; Viteri and Linares, 2019 ). For instance, common bean genotypes A 195, ‘Badillo,’ NY6020-4, PRA154, and PRA155 were reported with partial ASB resistance ( Viteri and Linares, 2017 ).…”

“…Conversely, two complementary genes, namely, Mp-1 and Mp-2 , conferred resistance in the A-70/BAT 477 cross in a controlled environment, and these genes were also derived from BAT 477 ( Olaya et al., 1996 ). More recently, Viteri and Linares (2019) reported that two complementary recessive genes and one recessive gene conferred resistance to ASB in the PC 50/’Othello’ and Badillo/PR1144-5 populations, respectively, in the greenhouse by the cut-stem method. These genes were apparently derived from Andean genotypes Badillo and PC 50.…”

Ashy stem blight (ASB) caused by the necrotrophic fungus Macrophomina phaseolina (Tassi) Goidanich is an important disease in common bean (Phaseolus vulgaris L.) in the Americas and worldwide. Low to intermediate levels of ASB resistance exist in cultivated and landrace genotypes of the common bean and the tertiary gene pool. However, cultivars with higher levels of resistance are not yet available. Our objectives were to 1) pyramid higher levels of resistance from multiple parent populations within the primary gene pool and 2) compare the response of the newly developed breeding lines (BL) with known sources of resistance. The BL UPR-Mp-22, UPR-Mp-34, UPR-Mp-42, and UPR-Mp-48, known sources of resistance, and susceptible checks were inoculated twice per plant with the PRI21 M. phaseolina isolate in the greenhouse and field trials conducted in Isabela and Lajas, Puerto Rico. None of the genotypes tested were resistant (mean scores 1–3). However, the new black UPR-Mp-42 and white UPR-Mp-48 BL had an intermediate response (mean scores 4–6) compared to white common bean genotypes ‘Bella,’ NY6020-4, and ‘Verano’ and black bean TARS-MST1 that were susceptible (scores ≥7) in all environments. Andean genotypes A 195, PRA154, PRA155, and UPR-Mp-22 were intermediate in the greenhouse. In contrast, UPR-Mp-34 had significantly lower scores than BAT 477 that had a susceptible reaction in the greenhouse in Isabela and in the field in Lajas and SEA 5 that was susceptible in all environments. These new BL possess an enhanced ASB resistance and may be used to improve common bean cultivars or germplasms of different market classes.

“…(1998b) reported that five QTL on Pv04, Pv06, Pv07, and Pv08 provided field resistance to ASB in the Dorado/XAN 176 RIL population, and they were derived from the black common bean XAN 176. More recently, Viteri and Linares (2019) identified two recessive genes and one recessive gene conferring resistance to M. phaseolina in PC 50/’Othello’ and ‘Badillo’/PR1144-5, respectively, under greenhouse conditions. These genes were derived from Andean genotypes PC 50 and Badillo.…”

Ashy stem blight (ASB), caused by the fungus Macrophomina phaseolina (Tassi) Goidanich is an important disease of the common bean (Phaseolus vulgaris L.). It is important to identify quantitative trait loci (QTL) for ASB resistance and introgress into susceptible cultivars of the common bean. The objective of this research was to identify QTL and single nucleotide polymorphism (SNP) markers associated with ASB resistance in recombinant inbred lines (RIL) derived from a cross between BAT 477 and NY6020-4 common bean. One hundred and twenty-six F6:7 RIL were phenotyped for ASB in the greenhouse. Disease severity was scored on a scale of 1–9. Genotyping was performed using whole genome resequencing with 2x common bean genome size coverage, and over six million SNPs were obtained. After being filtered, 72,017 SNPs distributed on 11 chromosomes were used to conduct the genome-wide association study (GWAS) and QTL mapping. A novel QTL region of ~4.28 Mbp from 35,546,329 bp to 39,826,434 bp on chromosome Pv03 was identified for ASB resistance. The two SNPs, Chr03_39824257 and Chr03_39824268 located at 39,824,257 bp and 39,824,268 bp on Pv03, respectively, were identified as the strongest markers associated with ASB resistance. The gene Phvul.003G175900 (drought sensitive, WD repeat-containing protein 76) located at 39,822,021 – 39,824,655 bp on Pv03 was recognized as one candidate for ASB resistance in the RIL, and the gene contained the two SNP markers. QTL and SNP markers may be used to select plants and lines for ASB resistance through marker-assisted selection (MAS) in common bean breeding.
