“…In 2014 cotton cultivar BRS 372 was released with high resistance level to RLS, cotton blue disease, and bacterial blight with a high fiber yield and high lint percentage cultivar (>42%) adapted to Brazilian savanna. From the same breeding program in 2017, an early mature cultivar BRS 416 was released with multiple disease resistance, combining RLS, blue disease and bacterial blight resistance (Suassuna et al 2019). Resistant cotton cultivars can drastically reduce the number of fungicide applications without reducing fiber yield.…”

Originated from the semi-arid highlands of Mexico, upland cotton (Gossypium hirsutum L.) accounts for more than 90% of world cotton fiber production. Intensively cultivated in Brazilian Cerrado since the early 1980s, the wet and warm environment of the region favors epidemics of fungal diseases such a Ramularia leaf spot, which emerged as the main disease of cotton cultivated in an area as large as one million hectares. Fungicides remain as the only resort to effectively control the disease and up to eight sequential sprays may be needed during the season. Research to improve disease management has been conducted during the last two decades including cultural, genetic, chemical and biological control methods. In this review we summarize current knowledge of the disease and the main findings and gaps on disease epidemiology and management and discuss on future direction towards a more sustainable management of a disease of greatest concern to cotton farmers in Brazil.

“…Regarding yield, the average in the same period was 3.597 kg/ ha (ABRAPA 2022). However, there are Brazilian cultivars with a yield potential above 4.000 kg/ha (Suassuna et al 2020).…”

Cotton is an essential worldwide commodity, and Brazil ranks fourth in world production and second in export. The present work aimed to gather the genealogies and estimate the genetic base of 109 Brazilian cotton cultivars released from 1932 to 2021. Twelve of the 68 ancestors identified contributed with 52.03% of the genes, and 33% of the cultivars resulted from the direct selection from landraces or old cultivars, evidencing a narrow genetic base. Over time, especially after 1990, the increases in the number of cultivars released and number of ancestors added to the breeding programs were driven by the need to reduce the cultivars' cycle for coexistence with pests and to make them suitable for mechanized cultivation in the new agricultural frontiers. However, Brazilian cotton cultivars still have a narrow genetic base, with the important participation of the ancestors CNPA SRI3, CKR 100W, C-77 and Express.

“…Thus, an enhanced fiber quality is essential for the competitiveness of cotton fiber in the textile industry. Moreover, along with conventional agronomic traits (Suassuna et al 2020), commercial biotechnological traits must also be improved in tropical environments to reinforce the pest and weed management and raise the competitiveness of Brazilian cotton (Suassuna et al 2018).…”
