1976 REGIONAL COTTON FUSARIUM WILT REPORT-
/
A. J. Kappelan, Jr. -
Elite breeding lines and cultivars submitted 
by 17 cooperators were
evaluated for resistance to Fusarium wilt. These materials were 
tested
on a field at Tallassee, Alabama, which was highly infested with the
Fusarium wilt fungus and root-knot nematodes. This test was originally
planted on April 23; however, stands were extremely poor, partially due
to unseasonably cold weather. Consequently, the field was disked and the
test replanted on May 19. Good stands were obtained from this second
planting. The first wilt symptoms did not appear until late July,
probably due to the late planting and dry weather through June.
The susceptible (Q Rowdene) and resistant ('McNair 511') were in-
cluded as checks. Rowden was planted in row 5 (15, 25, ... , 235) and
McNair 511 in row 10 (20, 30, ... , 240) and then in every tenth row there-
after throughout the test. Four replications of the other entries
arranged in a systematically randomized complete block design were
evaluated.
Initial live plant counts were made June 24. Wilted plants were

pulled and recorded on July 27, August 12, and September 
14. Final live
plant counts were also made on September 14. Differences 
between the
initial and final live plant counts were attributed to wilt 
losses. Per-
cent wilted plants per plot and mean wilting percentages for a given 
entry
were then determined.
Since wilting varied in different areas 
of a given replication due
to the large number of entries (243), as well as over replication,
critical evaluation of a given entry should be made 
relative to those
checks closest to the entry within each replication. 
The mean incidence
of wilt in Rowden ranged from 8.2 to 100% and averaged 62.2% for the
entire test (96 plots). Average wilting over the entire test for 
McNair
511 was 7.8% but wilt incidence ranged from 0 to 51.0%.
