Adptabilidade e estabilidade de soja convencional pela análise GGE biplot

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

A produção de soja convencional vem se restabelecendo a cada ano, pois o mercado internacional tem exigido produtos com elevado desempenho agronômico e qualidade nutricional, livres de organismos geneticamente modificados. Objetivou-se avaliar a adaptabilidade de genótipos de soja convencional na região sudoeste do estado de Goiás (Rio Verde, Montividiu e Santa Helena de Goiás), nas safras 2017/2018 e 2018/2019. Utilizou-se delineamento de blocos casualizados e foram testados oito genótipos (as cultivares BRS284, BRS283, BRS232, BRS317, NT11-1277, INT3459 e M6101 e a linhagem NT1478SP). Foram avaliados a produtividade de grãos e de óleo, bem como os teores de óleo e proteína. Análises multiambientes foram realizadas utilizando-se um modelo de variância residual heterogêneo, e a análise GGE biplot foi utilizada para descrever as inter-relações entre genótipos e ambientes. Os genótipos mais adaptados e estáveis foram BRS 317 para produtividade de grãos e BRS 283 para rendimento de óleo. Além disso, eles se comportaram de forma mais próxima do ideótipo para a região específica, enfatizando serem promissores. NT1478SP apresentou o maior teor de proteína. Na safra 2018/2019, Montividiu mostrou-se mais discriminativo para a produção de soja convencional, quanto à produtividade de grãos e de óleo.
