CUCUMBER SCAB RESISTANCE OF THE RIL

CUCUMBER SCAB RESISTANCE OF THE RILS. In the results for
2007, the DI for parental lines 9110Gt and 9930 were 17.5 and
83.6, respectively. The resistance of 9110Gt and the susceptibility
of 9930 to cucumber scab were confirmed. The F1
generation had a DI of 20.0, and was judged to be resistant.
There were 72 plants in the RIL population resistant to
cucumber scab with a DI < 45.0, and 76 plants susceptible to
cucumber with a DI > 45.0 (Fig. 1). The segregation of
resistance and susceptibility fit a ratio of 1:1 (Table 2).
In 2008, line 9110Gt had a DI = 12.8 in the artificial
inoculation, and was confirmed to be highly resistant to scab.
The DIs for line 9930 and the F1 generation were 76.9 and 20.0,
respectively. There were 71 plants in the RIL population resistant
to cucumber scab with a DI < 45.0, and 77 plants susceptible
to cucumber with a DI > 45.0 (Fig. 1). The segregation of
resistance and susceptibility fit a ratio of 1:1 (Table 2).
The results from 2007 and 2008 were consistent except for
one line of RILs. This line was identified as moderately resistant
with a DI of 38.9 in 2007. However, it was rated susceptible
with a DI of 45.7 in 2008. The reason may be due to environmental
conditions. Analysis of the data for parental lines, the
F1 generation, and the RIL population confirmed that a single
dominant gene controlled resistance to cucumber scab.

There were 72 Plants in the RIL population resistant to

In 2 008, line 9110Gt had a DI = 12.8 in the artificial

The Dis for line 9930 and the. F1 Generation were 76.9 and 20.0,
respectively. There were 71 Plants in the RIL population resistant
to Scab cucumber with a DI <45.0, and 77 Plants susceptible
to cucumber with a DI> 45.0 (Fig. 1). The segregation of
resistance and susceptibility Fit a ratio of 1: 1 (Table 2).
The results from 2 007 and the 2008th were consistent except for
one line of RILs. This line was identified as moderately resistant
with a DI of 38.9 in 2007. However, it was rated susceptible
with a DI of 45.7 in 2008. The Reason May be Due to Environmental
conditions. Analysis of the Data for Parental Lines, the
F1 Generation, and the RIL population confirmed that a single
