title: SolCAP 8K array genotyping of population 15143

description: The dataset is a tab-deliminted text file with genotyping information for
 a diploid potato progeny population derived from a cross of diploid potato
 clones 12120-03 X 07506-01. The SolCap 8303 Infinium Chip was used for SNP
 genotyping.  It was originally generated for study on genetic
 mapping of Verticillium wilt resistance.  The data was used again
 for analysis of segregation distortion in the most recent
 manuscript.  
description: Diploid potato clone 12120-03 was used as a female parent in a
 cross with male diploid parent 07506-01 to generate a F1 mapping
 population (15143) consisting of 91 clones. The male parent, 07506-01, was
 derived from pollination of W9306.2, with bulked pollen from 2 × hybrids.
 The female parental clone, 12120-03 was derived from a cross between 09113
 and 11 × 09753-01. The pedigree of both parental clones contains S.
 phureja and S. stenotomum. Disease-free seed tuber stocks of the potato
 clones were propagated in the field and maintained at the Benton-Ridge
 Substation of Agriculture and Agri-Food Canada in Benton, New Brunswick,
 Canada. The seed tubers from the clones were planted in an experimental
 field (45°52′ N, 66°31′ W) containing V. dahliae at the Fredericton
 Research and Development Centre of Agriculture and Agri-Food Canada in
 Fredericton, New Brunswick, Canada, on 22 May 2009. Planting in
 Fredericton was done in a randomized complete block design with three
 replicate plots of five hills (i.e., plants). Fertilizer was banded about
 7.5 cm to each side and 5 cm below the potato seed pieces at planting
 according to normal production practices at 200 kg N ha–1 as ammonium
 nitrate, 150 kg P2O5 ha–1, and 150 kg K2O ha–1. The plants were hilled in
 mid-July. Standard commercial practices were used for control of diseases,
 insects, and weeds. No irrigation was applied. Fresh
 leaf material (100 mg) from plants grown in the greenhouse for one month
 was pulverized in 2 mL lysing matrix “A” tubes (MP Biomedicals), using a
 FastPrep FP 120 for 40 s in 750 μL of the following extraction buffer: 1.4
 M NaCl, 20 mM EDTA, 2% CTAB (w/v), 0.1 M Tris pH 8.4, and 1%
 2-mercaptoethanol (v/v). The DNA suspension was incubated 60 min at 60°C
 after which it was mixed 1:1 with chloroform/isoamyl alcohol (24:1 v/v),
 and then centrifuged at 13,148g for 5 min. The supernatant was collected
 and 5 M NaCl added in a 1:40 v/v ratio before precipitation in 95% ethanol
 for 30 min at -20°C. The DNA was centrifuged at 13,148g for 10 min and the
 pellet washed in 70% ethanol followed by centrifugation for 5 min. The DNA
 was suspended in 150 μL sterile distilled water and treated with 1.5 μL of
 10 mg/ml DNase-free RNase. The SolCap 8303 Infinium
 Chip was used for single nucleotide polymorphism (SNP) genotyping using a
 procedure described in Felcher et al. (2012). The probe sequences and SNP information are available at http://solcap.msu.edu/potato_infinium.shtml [verified 13 Nov. 2017].

description: The file is a tab-delimited text file.  It can be opened with
 text reader or Microsoft Excel.  Column A is the SNP ID used in the study,
 Column B is the SolCap 8303 Infinium Chip ID, Column C is the chromosome
 position of the SNP in the DMv6.1 reference genome, Column D is the
 nucleotide position of the SNP, Column E is the genotype of the parents
 (12120-03 X 07506-01), Column F-CQ are the genotyping calls for the
 individual progeny (population 15143).
