The variety advancement dashboards are available publicly and were developed for all those involved in making variety advancement decisions for the Louisiana Sugarcane Variety Development Program. They are designed to contain the most accurate genetic values of varieties that are to be voted on for advancement in the annual advancement meeting. Every year, abundant data is collected from a series of selection trials that must be analyzed and reported to members of LSU AgCenter, USDA-ARS Sugarcane Research Unit, and the American Sugar Cane League to decide which varieties should be further evaluated. These dashboards contain raw data, modeled genetic values, trial reliability estimates, trial meta-data, additional metrics, and interactive features that were developed to help those responsible for advancement decisions explore the selection data on their own and make the most informed decisions. They are separated by year, assignment series, and selection stage so that individual trials can be analyzed the way they are intended.
This figure contains each variety’s predicted values of TRS (sucrose) and TCA (cane yield) on a biplot. The reference check cultivar (L 01-299) is always displayed in green and its values extend with the dotted grey line for each trait. Blue represents statistically similar sugar yield (the product of TCA and TRS) to the reference check, and any different color points represent significantly different sugar yield than the check. Values in the top left corner of the biplot represent the reliability of the trial for each trait (TRSH and TCAH) on a 0-1 scale and N represents the number of observations per variety for the trial.
This figure represents the predicted genetic values of sugar yield for each genotype and all of the crops harvested in this trial. In the given example, data was collected for PC and 1R. The point plot demonstrates sugar yield for each variety in each crop.
This table presents each variety’s DiDRI as outlined in (Blanchard et al., 2024). The value represents the percent sugar yield of that variety relative to the reference check (L 01-299) across the crop cycle. The index compares varieties to a reference check that should be considered a prolific ratooner.
These point plots represent the raw data collected from this trial for sugar yield (SPA), sucrose content (TRS), and cane yield (CY). They also contain the unadjusted mean (red dots), the predicted genetic values (purple dots), the standard error bars (red lines), and the standard error of the reference check cultivar (grey area).
This menu provides selectable items that can remove or add features to the figures. This can be useful when many varieties can crowd the figures, as the figure scales are autogenerated by the features displayed.
Standard Plotly features include .png generation, zoom, pan, box or lasso select, auto rescale, and reset selections to manipulate the features.
Hover features display the metadata that is connected to each individual datapoint. This can sometimes be informative when users consider where, when, and how each datapoint was obtained and how they might influence results. Currently displayed are variety, sugar yield (T_SPACRE), sucrose content (TRS_TON), cane yield (TCA), crop, and location.
