Differential equation describing the rate of development (RF) towards time-to-flowering as a function of genotype (g) and environmental (Tmax, Tmin, DL and Srad) factors at five experimental sites (s). This equation is represented by a linear mixed-effects function where: DLsgt = day length (hours) experienced by genotype gth on day t at site s, DLm = mean day length across all five sites (12.37 h); Sradsgt = solar radiation (Srad, MJ m−2 d−1) experienced by genotype gth on day t at site s, Sradm = mean solar radiation across all five sites (18.218 MJ m−2 d−1); Tminsgt = minimum temperature (°C) experienced by genotype gth on day t at site s, Tminm = mean minimum temperature across all five sites (16.128 °C); Tmaxsgt = maximum temperature (°C) experienced by genotype gth on day t at ste s, Tmaxm = mean maximum temperature across all five sites (27.458 °C); TF1j to TF12j = QTL operators for the jth allele (Calima alleles = +1 and Jamapa alleles = −1). For the rate equation: 0.02351 (d−1) is the mean effect of the environmental factors. QTL parameters are in green, and parameters of each environmental factor have their own color
