Supplemental Material for Adak et al., 2023

Supplementary files were stored in the "Data.zip" file containing necessary files to reproduce the prediction codes. FPCA.code.txt: Contains the FPCA R code for a combination of growing locations (Pop1: 2018, 2019 and Pop2: Drought and optimal trials in 2020, and drought trial in 2021), and two different flight durations (flights until flowering time, and full flights). CSV files: Files named FP.location.csv (e.g., FP.2018.csv) represent the results of flight-Pedigree interaction in equation 2 for each VI in each growing location. Files named FP.location.FPCA.until_flowering.csv (e.g., FP.2018.FPCA.until_flowering.csv) contain the results of FPCA analysis using the flight information of each VI until flowering times in each growing location. These files contain the first two FPCAs of each VI for each hybrid. Files named FP.location.FPCA.full_flights.csv (e.g., FP.2018.FPCA.full_flights.csv) present the results of FPCA analysis using all flight information of each VI in each growing location. These files also contain the first two FPCAs of each VI for each hybrid. GAPIT.Genotype.Numerical Pop1.txt and GAPIT.Genotype.Numerical Pop2.txt: These files comprise the numeric genomic data of Population 1 and 2, respectively. PHT.csv and Yield.csv: These files contain the plant height (cm) and grain yield (t/ha) BLUEs values for Pop1 and Pop2 grown in 2018, 2019, drought, and optimal trials in 2020, as well as the drought trial in 2021. They were utilized as predicted variables in the M1 to M5 prediction models. PHT.for.multitrait.csv and Yield.for.multitrait.csv: These files contain the plant height (cm) and grain yield (t/ha) BLUEs values, along with the FPCA1 value of VARI as a secondary trait for Pop1 and Pop2 grown in 2018, 2019, drought, and optimal trials in 2020, along with the drought trial in 2021. These data were used as predicted variables in the M6 prediction model. Prediction code M1 to M5.txt and Prediction code M6.txt: These files contain the prediction codes for M1 to M5 and M6 prediction models, respectively.
