Tecnologias de cultivares de sojas transgênicas e convencionais quanto a parâmetros relacionados à produtividade

Abstract

The soybean seed market is predominantly controlled by multinational companies, with a focus on the development of genetically modified organisms. To ensure sustainability and meet market demands, it is essential to value national capital companies and conventional soybean breeding programs. The key for Brazil is to embrace different technological levels, providing options for the use of conventional cultivars. Therefore, the hypothesis of this study is to investigate the viability of using both transgenic and conventional cultivars. The seed market is diverse and competitive, challenging producers to select an ideal variety for their situation with various technologies, including transgenic and conventional soybeans. The research aimed to evaluate soybean productivity in agronomic aspects based on transgenic versus conventional technology. A factorial design was employed, involving five conventional cultivars (GMS001, GMS002, GMS003, GMS004, and GMS005) and five transgenic cultivars (GMS001RR, GMS002RR, GMS003RR, GMS004RR, and GMS005RR), with three replications, across the 19/20, 20/21, and 21/22 harvests. Throughout the study, the cultivars' cycle, weight of a thousand seeds, productivity, plant height, first pod height, and flowering were assessed. The research concluded that the cultivars used did not show differences in productivity between conventional and transgenic technologies.
