Soybean grain quality with high protein and oil content is in high demand by domestic and international markets. The National Agricultural Research Institute of Uruguay (INIA) soybean breeding program aims to develop varieties that can meet those requirements.

Soybean is the most important crop in Uruguay. Stem canker caused by Diaporthe caulivora is one of the most yield limiting diseases, causing up to 24% yield losses.

ABSTRACT.- Random-regression models (RRM) are used for dairy cattle genetic evaluations in many countries. The output of a genetic evaluation with RRM is an estimated breeding value (EBV) for a specific function of the additive genetic random regression coefficients, say, 305-d milk yield and its corresponding reliability. The reliability of an EBV in RRM is calculated from the inverse of the coefficient matrix of mixed model equations (MME). The objective of this study was to develop an efficient method to approximate reliabilities for RRM with ssGBLUP.

Red-banded stink bug Piezodorus guildinii (P. guildinii) has been described as the most damaging stink bug regarding soybean crops, leading to seed injury, low germination percentages and foliar retention, even at low population densities. In this work the first P. guildinii transcriptome from a pool of all developmental stages was assembled, annotated and RNAi components were analyzed.
