BRS 336: a high-quality fiber upland cotton cultivar for Brazilian savanna and semi-arid conditions

Abstract

Cotton cultivar BRS 336 is a high-quality fiber upland cultivar and has wide adaptation to the Brazilian growing areas, with resistance to bacterial blight. BRS 336 exhibited fiber length higher than 32.0 mm in all field tests. Also, fiber strength exceeded all upland cotton currently grown in Brazil.

BRS 430 B2RF and BRS 432 B2RF: Insect-resistant and glyphosate-tolerant high-yielding cotton cultivars

“…Nowadays, more than 90% of cotton growing areas are located in this region. Genetic advances (Morello et al 2010, Morello et al 2012, Morello et al 2015, Barroso et al 2017) along with a better production system ensures high fiber yields, providing competitiveness to the Brazilian cotton in the international market. However, this tropical region is subject to high biotic stress pressure, highlighting pest damages (Bentivenha et al 2016) and weed competition (Salgado et al 2002).…”

BRS 368RF: A glyphosate tolerant, midseason upland cotton cultivar for Northeast and North Brazilian cerrado

“…Additionally, the cerrado of the North and Northeast regions is a distinct environment due to its high average temperature. Unfortunately, little effort has been made to develop upland cotton cultivars (Gossypium hirsutum L. r. latifolium Hutch) for this environment (Morello et al 2012a, Morello et al 2012b). …”

Environmental stratification in cotton in the presence or absence of genotypes with high ecovalence

“…The development and release of cotton cultivars in Brazil follows growers' demands for competitive lint yield, and fulfill industrial textile requirements, in particular in the Cerrado environment, the largest cotton growing area in Brazil (Morello et al 2010, Morello et al 2012, Morello et al 2015. Prior to cultivars being recommended, multiple trials (different locations and/or growing seasons) are carried out to evaluate genotypes in different growing conditions.…”
