1. Adaptability and Stability of Soybean Cultivars in Lowland Production System
ABSTRACT The objective was to study the adaptability and stability of soybean cultivars in the lowland production system under different conditions in a subtropical environment. Fourteen soybean cultivars were evaluated in five locations and three growing seasons in Rio Grande do Sul State, Brazil. Three sowing dates were evaluated in each location and growi

2. Agronomic performance of soybeans with the presence of volunteer RR corn
ABSTRACT The presence of volunteer corn plants among soybeans, both resistant to glyphosate, has increased in recent years in Brazil. The objective of this study was to quantify the impact on the agronomic performance in RR soybeans by the presence of volunteer RR corn in field conditions. The experiment was conducted in Tiradentes do Sul (RS), 2018/19 harve

3. Germination and vigor of soybean genotypes seeds under saline stress
RESUMO A soja destaca-se entre as culturas com maior aplicação da transgenia, principalmente para tolerância a herbicidas, pragas e doenças, mas são escassos estudos sobre estresse salino em plantas geneticamente modificadas. O objetivo desta pesquisa foi avaliar a tolerância ao estresse salino de genótipos de soja, tradicionais e geneticamente modifi

4. Source-sink relationship of soybean accessed by increasing in solar radiation through the plant canopy
ABSTRACT The photosynthetic metabolism is a key point to improve soybean yield. In this work, we demonstrated that radiation use by soybean plants can be improved, aiming to improve the grain yield in the lower canopy. The objective of this study was to observe whether the increase in solar radiation input in the canopy of soybean plants improves their yield

7. Superiority index based on target traits reveals the evolution of Brazilian soybean cultivars over last half-century
ABSTRACT The objective of this work was to assess the breeding influences in different agronomic and physiological traits in Brazilian soybean cultivars, released between 1965 and 2011, to identify traits associated with modern cultivars. A total of 29 cultivars were evaluated in two locations in the 2016/17 crop season. Genotype selection based on agronomic

8. Hole spacing in soybean hill drop sowing1
ABSTRACT The aim of this study was to evaluate the development, yield and its components of soybean sown in hill drop method with variation in hole spacing, compared to the conventional sowing method in lines. The experiment was conducted in a randomized block design, with six treatments and four replications, using the variety M7739 RR IPRO with four plans

9. Stability analysis of pure lines and a multiline of soybean in different locations
Abstract To compare agronomic performance and phenotypic stability among individual soybean lines and a multiline, eight cultivars and a mixture of them were evaluated in six environments in the 2014/2015 and 2015/2016 crop seasons. At maturity, grain yield (bg ha-1), lodging score, plant height (cm), and first pod height (cm) were evaluated. In the 2015/201

11. INT7100 IPRO - A soybean cultivar for an extensive growing area in the South and Cerrado in Brazil
Abstract Soybean cultivars with "plasticity" traits, such as good branching ability, ensure compensation of gaps in planting. The cultivar INT7100 IPRO provides excellent branching ability and plant architecture, facilitating control of pests and diseases, and it contains the biotechnology INTACTA RR2 PRO®. It is resistant to stem canker, brown stem rot, an

12. Pure line selection in a heterogeneous soybean cultivar
Abstract Although cultivars of autogamous plants are homogeneous genotypes, they may show natural variability due to mechanical mixing, natural hybridization, and mutation. The aim of the present study was to estimate genetic and phenotypic parameters and to identify and select superior genotypes that associate good performance in traits of interest from a h
