1981 REGIONAL COTTON FUSARIUM WILT REPORT
A. J. Kappelman, 
Jr.2
Cultivars and elite breeding lines submitted by 26 cooperators were
evaluated for fusarium wilt resistance under field conditions at the Plant
Breeding Unit, Tallassee, Alabama. The soil at this site is a Wickham sandy
loam highly infested with both the fusarium wilt fungus iFusarium oxysporum
Schlect. f. vasinfectum (Atk.) Snyd. & Hans.] and root-knot nematodes
(Meloidogyne spp.).
Plots were single 40-inch rows, 30 feet in length, separated by 6-foot
alleys and replicated four times. All entries were arranged in a systematic
design. 'Rowden' and'McNair 235' were used as the susceptible and the
resistant gradient checks, respectively. Rowden was planted in row 5 (15, 25,
... , 305) and McNair 235 in row 10 (20, 30, ... , 310) and then in every tenth
row thereafter throughout the test,
Plots were planted May 5, then thinned to three or four plants per foot
on.May 26. Initial live plant counts were made on June 24. Little wilting
occurred until mid-July. Just prior to the first scheduled wilt counts, this
test was sprayed with MSMA and a considerable number of the plants were
damaged. Some plants, especially in the susceptible check rows, displayed
considerable wilting at the time of herbicide application. However, within a
week after spraying, differences between wilt-and herbicide-damaged plants
could not be distinguished. On July 23 and 24 all plants with foliar damage

of any type were removed; therefore, actual wilting incidence was greater
than the data indicate. Wilted plants were counted and removed on August 20,
September 1, and 17, then remaining live plant counts were taken on September 21.
Percent of wilted plants per plot was determined based on the above counts, then
mean wilting for each entry was calculated.
Mean wilting for Rowden over the 124 rows evaluated was only 43.5%. This
low percentage is probably due to the loss of early data because of herbicide
damage. Wilting in Rowden varied from 0 to 100%. In contrast, only 2.5% of
the plants of the resistant check, McNair 235, wilted. Wilting in this check
ranged from 0 to 20%. Due to the loss of early information and the large
amount of variability of the susceptible check, wilt expression of a given entry
should be compared with that of the closest check rows.
Entries submitted by W. C. Johnson are commonly grown cultivars or highly
advanced materials; therefore, these are listed by name. Entries submitted by
other cooperators are listed by codes. Additional information regarding the
genetic background of a specific coded entry should be obtained from the given
cooperator.
