“…Among the methods available in the literature, Eberhart & Russel (1966) and Lin & Binns (1988) methods stand out in the recommendation of soybean cultivars in different environments (Matsuo et al, 2008;Polizel et al, 2013;Cargnelutti Filho & Guadagnin, 2018). Figure 3 shows the estimates of the environmental indices obtained by Eberhart & Russel method (1966) and allow characterizing the quality of the study sites.…”

Grain yield is a constant concern in soybean breeding programs for being highly influenced by the environment. This trait can be significantly affected by the sowing times. Thus, for the correct cultivar recommendation, methods of stability and adaptability analysis are used to verify the genotype x environment interaction at different sowing times. In this study, ten soybean cultivars were evaluated in 2016/2017 and 2017/2018 seasons, at different sowing times. Each experiment was carried out in a randomized block design with three replications. The methods of Eberhart & Russel and Lin & Binns were used for cultivars recommendation for general, favorable, and unfavorable environments. Cultivars CS2728, BONUS, and BRS1074 show high yield and predictability and therefore are the most suitable for the region of Chapadão do Sul.

“…Um dos aspectos mais importantes na produção de soja é a obtenção de sementes de alta qualidade, para serem utilizadas no estabelecimento das lavouras. Assim, o desenvolvimento de cultivares de soja com sementes de alta qualidade fisiológica e elevado potencial de conservação tem sido prioridade nos programas de melhoramento (ROCHA et al, 1990).…”

Intracultivar selection for seed quality of soybeans in an ultra-low-density selection model (Honeycomb Selection Designs)

et al. 2020

Selecting genotypes that combine high productivity with high seed quality is a challenge. The exploration of intracultivar genetic variation is an alternative to significantly increase the annual genetic gain and maximize the selection efficiency for both characteristics. The present study aimed to identify intracultivar variation to improve the seed quality of soybean genotypes derived from the commercial cultivar BRS 284, selected using the HSD (Honeycomb Selection Designs) model. Soybean genotypes selected for two years from two environments with contrasting edaphoclimatic characteristics, according to the principles of the HSD selection model, were cultivated under competition by using the experimental model in randomized blocks with four replicates and evaluated regarding the productivity and physiological quality of seeds. The results showed that genotype 284-3 presented a greater mass of 100 seeds, germination, vigour after accelerated ageing test, seedling emergence and emergence speed index than the other genotypes in both environments, with no significant difference in the standard cultivar regarding seed yield. The HSD method was an efficient selection method to identify intracultivar variation to improve cultivar performance.
