superior for the protein percent and the value
was (7.20) , low protein percent was observed in
inbred line (10) scoring (5.70), while the inbred
line (8) was superior for oil percent (5.98) low
oil percent was showed in inbred line (10) and
the value reached (4.29) . The inbred line (7)
was superior for ear diameter (2.23 cm) the
fewer diameters for ear for ear showed in inbred
line (1) and the value was (1.66 cm) .

Data in table (4) indicate a preference of
genotypic and phenotypic for yield/ plant, and
the leaf area of the spring season and yield/ plant
and ear height of the autumn season. The values
for all the studied characters was high but the
highest was for number of kernels/ ear and leaf
area for the spring season while in autumn the
highest heritability was for plant
height and number of days to 50 % silking.
Number of days to 50 % tasseling and silking
showed the least genotypic and phenotypic
coefficient, so improvement by selection method
through these two characters is very week. But
using mass selection method through yield per
plant is effective to improve the yield depending
on genotypic variance the results agree with) (13) .
The data in Table-5 and 6 depicted
correlations of traits with kernel yield/ plant
studied as was found in previous findings (1) . Ear
length acted the same behavior in its correlation
with kernel yield/ plant during spring and
autumn season and give a positive significant
genotypic and phenotypic with kernel yield/
plant and leaf area.
The number of kernels/ ear had a positive
significant genotypic and phenotypic correlation
with leaf area. Weight of (300) kernels showed
negative significant genotypic with number of
row/ ear in autumn season but correlation
with other characters was not significant
also ear diameter did not show any
significant genotypic and phenotypic
association with leaf area.
Table (7) shows in spring season that the
number of kernels per ear exerted direct positive
effect on kernel yield per plant but in direct
effect through ear length, number of rows/ ear,
leaf area and (300) kernels weight also exerted
positive direct effect on kernel yield/ plant. The
results are partially in agreement (8) . From the
same table for the autumn season it can be
noticed of rows/ ear exerted direct positive effect
on kernel yield/ plant but indirect effect through
ear length, and number of kernels/ ear. The trait
(300) kernels weight was the second in the direct
influence on kernel yield per plant because its
indirect influence was wreak, so these characters
can be used to improve the yield through the
selection method of these characters to achieve
the aim. These data are in agreement with those
(13) , (2) , (5) , (15) , (14) . It can be concluded that the
number of kernel/ ear, leaf area and kernel yield/
plant where to be considered for improvement of
high genotypic variability and heritability in
broad sense in breeding material studied.
