Abstract
Abstract BRS 372 and BRS 416 are cotton cultivars with high lint yield and genetic resistance to the main cotton diseases in Brazil, particularly to Ramularia Leaf Spot. They have stable yields, good fiber quality and can contribute to a sustainable cotton disease management in tropical environments.
Highlights
Cotton (Gossypium hirsutum L.) is an important commodity in the global agricultural economy
Diseases previously considered secondary or new diseases, e.g., Ramularia Leaf Spot (RLS), caused by the fungus Ramulariopsis pseudoglycines, can become epidemic. The latter cotton disease has a high economic relevance since up to eight fungicide applications per season are required to control it in a production area of more than 1.000,000 hectares (Silva et al 2019)
This paper describes the development of the conventional cotton cultivars BRS 372 and BRS 416 as part of an ongoing effort to create new cotton lines and cultivars with improved yield potential and resistance to one or several diseases, adapted to the Brazilian cerrado
