AGRONOMIC PERFORMANCE AND SELECTION OF IDEAL SOYBEAN GENOTYPES

Abstract

The study aimed to evaluate agronomic performance and select ideal soybean genotypes. The experiment happened at the Missions Agronomic Research and Results Center (CPRAM), located in Entre-Ijuís - Rio Grande do Sul, South Region of Brazil. The experiment used random blocks with 36 different types of soybeans in four different tests. The units of the experiment were 40 square meters. The research evaluated morphological and productive characters and meteorological data from the experiment's environment. The MGIDI index selected the genotypes DM 5958, BMX ZEUS, NS 6601, BMX FIBRA, and P 95R51 by potentiating the variables number of legumes per plant, the number of grains per plant, the thousand-grain weight, and the grain yield. The genotype selection with higher grain yield can be performed indirectly through the number of legumes per plant and legumes on the main stem.
