This study aimed at checking the stability of some mutant lines from
soybean varieties in different locations and to select the best performing lines in
each location.
These lines 15 were selected according to previous experiments as being
early
maturing and/or that yield higher than the control. The study lasted three
years, the experiment plants were grown in 3 locations: Raqa, Idleb and
Lattakia. The experiment was designed as RCBD with 3 replicates for each
variety.
Results showed significant difference between lines, Locations and year in
both earliness and yield, A significant interaction was realized between (line X
location) and (line X year) for earliness and yield. For earliness (line X year)
was not significant. The reverse situation was realized for yield. Location. X
year of yield and earliness was significant. Earliness was correlated positively
with all characters (except for 100-seed-weight).
Yield was positively and significantly correlated with characters of all lines.
Three lines with higher yield than the control (142.61%) and same maturity
time were selected.
