| The objective of this study was to evaluate the performance of cotton genotypes and resistance ramularia leaf spot in two sowing dates. The experimental design was a randomized block with 18 genotypes of cotton and 5 repetitions. They assessed the area under the disease progress curve (AUDPC) and yields, to which were held 8 reviews of disease severity in each third of the plant, lower, middle and upper. The IMA 08-12427 genotype showed lower average total AUDPC, regardless of sowing time. Regarding yield, TMG 82 WS genotypes BRS 371, DP 555 BG RR, FM 982 GL and BRS 372 obtained the highest yield in the first seeding time, ranging from 3,021.97 to 3,623.57 kg ha-1, and classified as resistance as MR, MR, MS, S, MS, respectively. Among the 18 genotypes, the... |
