Determining Mega- environments the best figure in
any location
Biplot explains the diagram of 95.16% of yield
variance of data. In the figure, 4 parts is created by
lines perpendicular to the sides of the polygon can be
seen. Places are needed in these areas. Other
genotypes are (with the exception of the genotypes in
vertices) the need to be located within the polygon.
Azargol, Arena, Terra, Almanzor cultivars are located
in the corners or vertices of the polygon. Karaj and
Birjand and Isfahan locations are located part in the
Azargol and Almanzor cultivars are located at the top
of the section. In fact, such an interpretation of the
varieties Almanzor and Azargol were best genotypes
for Karaj, Isfahan Birjand locations. Sari place in a
part located at the top of the cultivar Azargol, This
means that Azargol cultivars best genotype is for the
location Sari. The Alisson, Mas96a, Pomar, Vidoc,
Terra, Arena genotypes are located in areas that have
no place in sectors.
Another feature Biplot is shown that the grouping
environment. The point is to identify different Mega-
environments. Sari and Isfahan location were formed
in the first Mega- environment, Birjand and Karaj also
known as the second Mega- environment (Figure 3).
According to Figure 4, Azargol was the highest
performance and Terra was the lowest yield. Average
genotypes are as follows:
