DATA FILE (1)

1. \Data\DATA_NRO_115_117_119.csv: Comma-delimited ASCII text file containing data from three red oak (Quercus rubra) progeny trial plantations managed by the USDA Forest Service, Northern Research Station, Hardwood Tree Improvement and Regeneration Center (HTIRC). Data include both quantitative and qualitative data (categorical ratings) used to investigate trait heritability, the effectiveness of a binary system (1/0) for rating and evaluating juvenile red oak form, and the form trade-offs resulting from selection for height and diameter growth. Individuals are identified in rows, columns contain data (measurements, see below); some columns indicate (1/0) whether data were used in analysis, additional columns indicate date and time of measurement or location and identity of tree within the plantation (i.e., Rep, Column, Row and Family). This file is the complete set of data used in the analysis represented in Woeste et al. (2021).

Variables include:

Treeid = tree id (site - year planted - column - row)

Site = site (plantation)

Rep = replication in plantation = block (site 115 has 20 blocks, site 117 has 28 blocks, and site 119 has 25 blocks)

Column = column number in plantation in which the tree was planted

Row = row number in the plantation in which the tree was planted

Family = female half-sib progeny to which the tree belongs. Family name identifies female parent tree. (Families followed by “jp” were seeds harvested at the Jasper Pulaski State Tree Nursery operated by the State of Indiana. Families followed by “v” were seeds harvested from the indicated family at the Vallonia state tree nursery, Vallonia, Indiana. This convention was used because the same genotype (clone) was propagated into two different seed orchards in Indiana: the Jasper-Pulaski nursery and the Vallonia nursery. Seedlings of the same family that derived from different nurseries may have different characteristics, but because the seedlings are considered half-siblings (open pollinated) there is no reason, prima facie, to treat them differently. It is possible but not likely that the “jp” ramet has a different genotype from the “v” ramet due to propagation errors.)

PlantYear = year seedling was planted

Eval_if_equ_0 = if tree was evaluated it was assigned ‘0’. Some families excluded because of insufficient replication in one or more of three red oak plantations, some trees excluded if seriously deformed, dead, resprouted from dead stem, obviously not red oak.

Log12ft_1_equ_Y = a trait we did not evaluate but include here for completeness. It was a subjective rating of whether, on the date of rating, the tree did (= 1) or did not (=0) show a 12 foot, merchantable log, not in terms of diameter but in terms of straightness and freedom from defect.

BrAng_1_equ_gr45 = if branch angle (average angle of branches below 3.7 meters measured adaxially) was greater than (+) 45 degrees it was assigned '1'

No_brch_gr_1_in = number of branches on the stem with diameter greater than 2.5 cm

No_brch_gr_1_in_BIN = if the number of branches on the stem with diameter greater than 2.5 cm was greater than or equal to three, then the tree was assigned a ‘1’ in this column, otherwise it was assigned a ‘0’.

Sweep_1_equ_none = a tree showing an off-center deviation of more than 1/3 of the stem diameter in the bottom 3.7 m of stem or deviation > 1/4 stem diameter in two or more planes was rated as showing sweep (rated ‘0’), otherwise the tree was rated ‘1’.

Height_cm = tree height (cm), measurements were made in decimeters and converted to cm

DBH_mm = diameter (mm) at breast height (1.37 m from the ground)

vol_cm3 = stem volume (cubic cm) calculated using the formula [(diameter)2 *height]. This equation does not include taper and is used to provide a rough estimate of overall tree size.

Yr = number of growing seasons in plantation. This age does not include the year the trees grew in the nursery before lifting.

MeasurementDate = date and time of measurement


SUPPLEMENTAL FILES (4)

1. \Supplements\NRO_115_117_119_MAIN PROGRAM FILE.sas: ASCII text file containing SAS code for calculation of all summary statistics, heritabilities, breeding values, Genotype x environment interactions, variance components, tests of normality, Best Linear Unbiased Predictions (BLUP), and gain calculations for the data included in this data publication. This file is included for the convenience of those who are familiar with SAS code and its use in forest genetic analysis. Code is amply annotated with comment to guide the user. Family is abbreviated “Fam”.

2. \Supplements\NRO_plot_115_map.csv: Comma-delimited ASCII text file containing a numeric map of plantation 115 to aid in visualization. Family information is provided for each tree by row (1-50) and column (1-45) of the plantation. Note that North is at the top and West is to the left. (Note: “buo” = bur oak; “ck” was planted as a “check lot” composed of unselected red oak sold to the nursery as bulk seed; and “? bled” is a notation that this tree may not be red oak but instead may be a hybrid between black oak [Quercus velutina] and red oak – we have no evidence besides morphology for hybridity so it remains incertae sedis.)

3. \Supplements\NRO_plot_117_map.csv: Comma-delimited ASCII text file containing a numeric map of plantation 117 to aid in visualization. Family information is provided for each tree by row (1-98) and column (1-32) of the plantation. Note that North is at the top and West is to the left. (Note: “buo” = bur oak and “ck” was planted as a “check lot” composed of unselected red oak sold to the nursery as bulk seed)

4. \Supplements\NRO_plot_119_map.csv: Comma-delimited ASCII text file containing a numeric map of plantation 119 to aid in visualization. Family information is provided for each tree by row (1-50) and column (1-51) of the plantation. Note that North is at the top and West is to the left. (Note: “Bur” = bur oak and “ck” was planted as a “check lot” composed of unselected red oak sold to the nursery as bulk seed)
