Expected mean squares for phytochemicals and forage yield traits across two environments (non-stress and drought stress) and in 2018 and 2019 seasons for evaluation of Poa pratensis accessions.

Source of variation	Degree of freedom	Expected mean squares
Block	r − 1 = 1
Genotype	g − 1 = 99	${\sigma }_e^2+{r\sigma }_g^2$
Error	(r − 1) (g − 1) = 99	${\sigma }_e^2$

g, genotype; r, number of block, ${\sigma }_e^2$, error variance; ${\sigma }_g^2$, genotypic variance.
