These data have been collected in order to assess the predictive ability
of genomic prediction models across varying environmental conditions in
Haiti, employing two statistical methods. Our assessment encompassed
twelve distinct sorghum traits, with genomic predictions conducted both
within and across irrigated and water-stress treatments (water stress and
water stress 2). The irrigated condition was watered weekly throughout the
growing season, and the soil moisture content one week after planting was
77%, with the moisture content never dropping below 50% during the growing
season. For water stress 1, plots relied on residual soil moisture and
experienced an increase in soil moisture content to 76% due to rainfall
during the hard dough stage. A 5 m buffer area separated irrigated and
water stress 1 blocks, which also served as a border. For water stress 2,
plots were also grown on residual soil moisture. Soil moisture content
stood at 74% one week after planting and decreased to 17% by the end of
the flowering stage (Figure 1). The latter condition is considered more
severe due to slight soil salinity in addition to water stress treatment.
This salinity is approximately 0.6 dS/m. The electrical conductivity was
measured, using the electrometric method, on the extract of the saturated
paste.
