| Summary: | The 1985 and 1986 Cotton Reports have the same publication and P-Series numbers. === Verticillium wilt tolerance and varietal response were factors in lint yield in this test. Highest yields were obtained from the first planting on 8 April. The 19 April planting had a lower average yield than the 7 May planting, probably because of poorer stands. Lint yields decreased an average of 5 pounds of lint/acre/day between 8 April and 7 May; 9 pounds between 7 May and 24 May; and 15 pounds between 24 May and 10 June. Deltapine (DP) 90 had the highest lint yield for the first two plantings and was among the highest for all plantings. DP 30 was highest in lint yield for the third and fourth plantings and high at other planting dates. Wilt tolerance was a factor in DP 30 performance. If the price premium for pima lint is considered, P-62 was superior to all upland cottons for the first four plantings and Pima S-6 was for the first three plantings. Wilt tolerance was undoubtedly a factor in the pima cotton performance.
