2.3 Statistics
The analysis of variance in flowering dynamics (i.e., tasseling,
shedding, silking, ASI), yield, KN/ear, and TKW were performed using SAS
Statistics 9.4. The significant differences between different maize
inbred lines were compared using the least significant difference test
(LSD) at P < 0.05, 0.01, 0.001. Variance Partitioning Analysis
(VPA) was conducted to calculate the relative contributions of sowing
date, inbred line, and residual factors to yield parameters with R
language lme4 package. Correlations between the daily maximum
temperature (DMT), solar radiation (SR), rainfall (RF), flowering
dynamics, KN/ear, TKW, and yield were performed with correlation plot of
Originpro 2021.
