Main results for the mixed analysis combined for both well-watered and periodic drought-stress treatments.

F tests for the fixed effect of treatment (T), block within treatment [B(T)], population (P), population × treatment interaction (P*T), for the covariates of days for germination (DG) and height at the beginning of the experiment (H2), estimates of variance components of the random effects and their significance based on likelihood ratio tests, individual () and family means () heritability estimates, and their standard errors and coefficients of additive genetic variance ().

本数据集涵盖针对处理（T）、处理内区组[B(T)]、种群（P）、种群×处理互作（P*T）的固定效应F检验，以及针对发芽天数（DG）、实验初始株高（H2）两个协变量的对应检验；同时包含随机效应的方差组分估计值、基于似然比检验得到的组分显著性结果，还包括个体（）与家系均值（）的遗传力估计值，及其标准误和加性遗传方差系数。
