Identification and Mapping of Late Blight Resistance Quantitative Trait Loci in Tomato Accession PI 163245.
Article in The plant genome, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Late blight (LB), caused by the oomycete (Mont.) de Bary, is one of the most devastating diseases of tomato ( L.) and potato ( tuberosum L. worldwide. The importance of LB on tomato has increased due to the occurrence of aggressive and fungicide-resistant clonal lineages of . Consequently, identification and characterization of new sources of genetic resistance to LB has become a priority in tomato breeding. Previously, we reported accession PI 163245 as a promising source of highly heritable LB resistance for tomato breeding. The purpose of this study was to identify and map quantitative trait loci (QTLs) associated with LB resistance in this accession using a trait-based marker analysis (a.k.a. selective genotyping). An F mapping population ( = 560) derived from a cross between a LB-susceptible tomato breeding line (Fla. 8059) and PI 163245 was screened for LB resistance, and the most resistant ( = 39) and susceptible ( = 35) individuals were selected for genotyping. Sequencing and comparison of the reduced representation libraries (RRLs) derived from genomic DNA of the two parents resulted in the identification of 33,541 putative single nucleotide polymorphism (SNP) markers, of which, 233 genome-wide markers were used to genotype the 74 selected F individuals. The marker analysis resulted in the identification of four LB resistance QTLs conferred by PI 163245, located on chromosomes 2, 3, 10, and 11. Research is underway to develop near-isogenic lines (NILs) for fine mapping the QTLs and develop tomato breeding lines with LB resistance introduced from PI 163245.
