The recombination landscape and multiple QTL mapping in a Solanum tuberosum cv. ‘Atlantic’-derived F1 population

AbstractThere are many challenges involved with the genetic analyses of autopolyploid species, such as the tetraploid potato, Solanum tuberosum (2n = 4x = 48). The development of new analytical methods has made it valuable to re-analyze an F1 population (n = 156) derived from a cross involving ‘Atlantic’, a widely grown chipping variety in the USA. A fully integrated genetic map with 4285 single nucleotide polymorphisms, spanning 1630 cM, was constructed with MAPpoly software. We observed that bivalent configurations were the most abundant ones (51.0~72.4% depending on parent and linkage group), though multivalent configurations were also observed (2.2~39.2%). Seven traits were evaluated over four years (2006–8 and 2014) and quantitative trait loci (QTL) mapping was carried out using QTLpoly software. Based on a multiple-QTL model approach, we detected 21 QTL for 15 out of 27 trait-year combination phenotypes. A hotspot on linkage group 5 was identified with co-located QTL for maturity, plant yield, specific gravity, and internal heat necrosis resistance evaluated over different years. Additional QTL for specific gravity and dry matter were detected with maturity-corrected phenotypes. Among the genes around QTL peaks, we found those on chromosome 5 that have been previously implicated in maturity (StCDF1) and tuber formation (POTH1). These analyses have the potential to provide insights into the biology and breeding of tetraploid potato and other autopolyploid species.

Chemical vine desiccation of potato (Solanum tuberosum L.) is widely used in the USA. Diquat is the major vine desiccant but has some drawbacks such as incomplete stem desiccation allowing regrowth. A new herbicide, UCC-C4243, was evaluated as a replacement for diquat. The potato cultivar `Atlantic' was treated with UCC-C4243 (a.i.) at 0.25 to 2.5 oz/acre (17.5 to 175 g·ha-1), and leaf and stem desiccation efficiency was compared to diquat (a.i.) at 4 oz/acre (280 g·ha-1). Split applications of UCC-C4243 were compared to double applications of diquat. Subjective evaluations were made on regrowth and tuber skinning, and objective measurements on specific gravity and yield. Trials were conducted from 1991 to 1995 at Scottsbluff, NE. UCC-C4243 at 1.5 oz/acre (105 g·ha-1) and higher significantly increased leaf and stem desiccation compared to diquat. There was no difference between single and split applications of UCC-C4243. UCC-C4243 suppressed regrowth at 1 oz/acre (70 g·ha-1) and prevented it at 2.5 oz/acre at 3 weeks after treatment while diquat did not. Skin set of tubers was promoted equally by all desiccants. Specific gravity was not lowered by UCC-C4243 but was by diquat. Yields were not affected by either UCC-C4243 at 1.5 oz/acre or diquat at 4 oz/acre. UCC-C4243 was more effective than diquat as a vine desiccant without the regrowth and tuber specific gravity effects associated with diquat.

Randomly amplified polymorphic DNA (RAPD) molecular markers were used to construct a partial genetic linkage map in a recombinant inbred population derived from the common bean (Phaseolus vulgaris L.) cross PC-50 × XAN-159 for studying the genetics of bacterial disease resistance in common bean. The linkage map spanned 426 cM and included 168 RAPD markers and 2 classical markers with 11 unassigned markers. The seventy recombinant inbred lines were evaluated for resistance to two strains of common bacterial blight [Xanthomonas campestris pv. phaseoli (Smith) Dye] (Xcp). Common bacterial blight (CBB) resistance was evaluated for Xcp strain EK-11 in later-developed trifoliolate leaves and for Xcp strains, DR-7 and EK-11, in first trifoliolate leaves, seeds, and pods. One to four quantitative trait loci (QTLs) accounted for 18% to 53% of the phenotypic variation for traits. Most significant effects for CBB resistance were associated with one chromosomal region on linkage group 5 and with two regions on linkage group 1, of the partial linkage map. The chromosomal region (a 13-cM interval) in linkage group 5 was significantly associated with resistance to Xcp strains DR-7 and EK-11 in leaves, pods, and seeds. The regions in linkage group 1 were also significantly associated with resistance to both Xcp strains in more than one plant organ. In addition, a seedcoat pattern gene (C) and a flower color gene (vlae) were mapped in linkage groups 1 and 5, respectively, of the partial linkage map. The V locus was found to be linked to a QTL with a major effect on CBB resistance.
