1979 REGIONAL COTTON FUSARIUM WILT REPORT'
A. J. Kappelman, Jr.

Cultivars and elite breeding lines submitted by 20 cooperators were
evaluated for fusarium wilt resistance under field conditions at Tallassee,
Alabama. These materials were evaluated on a Wickham sandy loam soil which
was highly infested with both the fusarium wilt fungus [Fusarium oxysporum
Schlect. f. vasinfectum (Atk.) Snyd, & Hans.] and root-knot nematodes
(Meloidogyne spp.). Both the susceptible ('Rowden') and resistant
('Stoneville 
603
') cultivars were included as checks. Rowden was planted
in row 5 (15, 25, .. ,, 145) and Stoneville 603 in row 10 (20, 30, ...,
-140) and then in every tenth row thereafter throughout the test.
All plots were bedded, 30 ft in length, spaced 40 in apart, and
separated by 6-ft alleys. Four replications of the test entries were
arranged in a systematically randomized complete block design. Entries
were planted May 3 and thinned to one plant every 3 or 4 inches on June 5.
Initial live plant counts were taken June 12. Wilted plants were counted
and removed five times during the growing season. Final counts of live
plants were made on September 6, Percent wilted plants per plot were
determined as the difference between initial and final live plant counts.
Mean wilting percentages for a given entry were then calculated.
Environmental conditions during the growing season were somewhat
unusual. Minimum air temperature was lower than 60 F until May 27 while

the interpretation of which may be modified with additional experimentation.

maximumair temperatures of 90 F or above occurred only on 15 days during
the entire test period. In addition, rainfall was somewhat limiting.
Regardless of this, a great deal of-wilting occurred although considerable
variability was evident, Average wilting over the entire test for Rowden
was 75% but wilt incidence .ranged from 21,1 to 100%. The mean incidence
of wilting in Stoneville 603 was only 18% but ranged from 0 to 48.1%.
Thus-, while extremely resistant or susceptible entries could be easily
distinguished, the variation across replications makes an entry with
intermediate resistance difficult to classify. Critical evaluation of an
check cultivars.
Entries submitted by Wiley C, Johnson are commonly grown cultivars or
highly advanced commercial materials; therefore, they are listed by name.
Entries submitted by other ooperators are listed by their coded number,
Additiona information regarding the genetic background of 
a specific coded
entry should be obtained from the given cooperator.
