Abstract

Abstract: BRS 500 B2RF is a high-yielding cotton cultivar with transgenic resistance to lepidopteran pests and tolerance to the herbicide glyphosate. Additionally, BRS 500 B2RF has resistance to Ramularia leaf spot and partial resistance to root-knot nematode. It represents an important contribution to sustainable cotton production in Brazil.

Highlights

Cotton (Gossypium hirsutum L.) is the most important natural textile fiber in the world
BRS 432 B2RF is a transgenic cultivar that carries insect resistance and herbicide tolerance through the Bollgard II® (B2) and Roundup Ready Flex® (RF) events (MON 15985 and MON 88913, respectively), though it is susceptible to Ramularia leaf spot disease (RLS)
The cultivar BRS 500 B2RF is resistant to bacterial blight (BB), cotton blue disease (CBD), RLS, and root-knot nematode (RKN) (Table 1)
