Cultivars and elite breeding lines submitted by 18 cooperators as well as all entries in the boll-budworm resistant and frego bract

regional tests 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.). Susceptible ('Rowden') and resistant ('McNair row 5 (15, 511') 25, cultivars were ... , 265) and

included as checks. McNair 511 in

Rowden was planted in 30,

row 10 (20,

randomized complete block designs, were evaluated.

The first

planting of this test made April 24 resulted in

excellent

emergence and early seedling growth; however,

a sandstorm over the

weekend of May 13 reduced stands on 90% of the test to less than 10 plants per row. Consequently, the entire test was replanted on May 18.

Good stands were also obtained from this second planting and plots thinned to one plant per 3 to 4 inches. made July 10. and August 17. Initial live plant counts were August 1,

Wilted plants were pulled and recorded July 20,

Final live plant counts were then taken on August 27. and final live plant counts were attri-

Differences between the initial buted to wilt losses.

Percent wilted plants per plot and mean wilting

percentages for a given entry were then determined. Average wilting over the entire test (162 plots) for McNair 511 was 5.3% but incidence ranged from 0 to 22.2%. in Rowden ranged fron The mean incidence of wilting

18,2 to 97.4% and averaged only 54% for the entire the resistant check, McNair 511, was the

test.

The mean wilting in

lowest ever since this entry has been tested while that for Rowden was the lowest in the past 16 years. This low incidence of wilt may be thus later maturation of the

attributed partially to the late planting,

plants, as well as the fairly droughty growing season. Since wilting varied in different areas of a given replication, the tests, as well as

partially due to the large number of entries in over replications,

critical evaluation of a given entry should be made

relative to those checks closest to the entry within each replication. Evaluation of breeding progress or evaluation of entries over years probably should be made only between values determined relative to the mean wilting of Rowden for a given year.
