A direct consequence of Fortin's criterion and the previous lemma is that, if Th f is nondegenerate and has no triangle with two edges on [beta][[OMEGA].sub.f] f, then (Xhf , Mhf) satisfies the inf-sup condition; see (5.2) and (5.3).
Formulae from Fischer and Maurer (1978) were adopted to calculate low soil fertility intensity index (LFII) for each growing season (and location) as LFII = 1 - Xlf/Xhf, where Xlf and Xhf are the mean of all genotypes under LF and HF environments, respectively.
([double dagger]) LFII, low soil fertility intensity index = 1 - Xlf/ Xhf, where Xlf and Xhf are the mean of all genotypes in low and high soil fertility environments, respectively.
