Agronomic performance of super-sweet corn genotypes in the north of Rio de Janeiro. Repositório Alice
SANTOS, P. H. A. D.; PEREIRA, M. G.; TRINDADE, R. dos S.; CUNHA, K. S. da; ENTRINGER, G. C.; VETTORAZZI, C. F..
We investigated the agronomic performance of super-sweet corn genotypes. Super-sweet corn genotypes were backcrossed with regionally adapted field varieties (CIMMYT 8 and Piranão 8). Eight morphological and yield-related traits were evaluated. A significant effect of interaction was observed between the five groups of genotypes (donor parents; super-sweet backcrossed parents; super-sweet intervarietal hybrids; common intervarietal corn hybrids; and field corn populations). Despite the low yield of genotype SH 2 Piranão, the hybrids resulting from interbreeding of the backcrossed parents for the improvement of super-sweet corn were promising. The agronomic performance of the super-sweet parents and their hybrids indicates the possibility of breeding lines...

Combined selection for adaptability, genotypic stability and cowpea yield from mixed models. Repositório Alice
CRUZ, D. P. da; GRAVINA, G. de A.; VIVAS, M.; ENTRINGER, G. C.; SOUZA, Y. P. de; ROCHA, R. S.; JAEGGI, M. E. P. da C.; ALBUQUERQUE, D. P.; AMARAL JUNIOR, A. T. do; GRAVINA, L. M.; ROCHA, M. de M.; SILVA, R. de K. G. da.
The potential expression of crop productivity is a constant challenge for plant breeders in the face of oscillations in environmental variables, making selection difficult and increasing the operational and methodological costs in obtaining the ideal cultivar for a determined region. The objective of the research was to investigate the effects of genotype x environment interaction in the selection of cowpea lines with high grain yield, adaptability, and genotypic stability simultaneously, in environments of the Northwest region of Rio de Janeiro State, using mixed models (Maximum Restricted Likelihood - REML/Best Linear Unbiased Prediction - BLUP).

Genetic control of leaf curl in maize. Repositório Alice
ENTRINGER, G. C.; GUEDES, F. L.; OLIVEIRA, A. A.; NASCIMENTO, J. P.; SOUZA, J. C..
Abstract: Among the many implications of climatic change on agriculture, drought is expected to continue to have a major impact on agribusinesses. Leaf curling is an anatomical characteristic that might be potentially used to enhance plant tolerance to water deficit. Hence, we aimed to study the genetic control of leaf curl in maize. From 2 contrasting inbred lines for the trait, generations F1 , F2 , and the backcrosses were obtained. All of these generations were evaluated in a randomized block design with 2 replicates. Leaf curl samples were collected from 3 leaves above the first ear at the tasseling stage, and quantified by dividing the width of the leaf blade with natural curling against its extended width. The mean and variance components were...

'UENF 506-11': a new maize cultivar for the North and Northwest of Rio de Janeiro State. Repositório Alice
PEREIRA, M. G.; BERILLI, A. P. C. G.; TRINDADE, R. dos S.; ENTRINGER, G. C.; SANTOS, P. H. A. D.; VETTORAZZI, J. C. F.; GALVÃO, K. S. da C..
The intervarietal hybrid ?UENF 506-11? was derived from full-sib maize families in the 11th cycle of reciprocal recurrent selection. It produces a grain yield of 7.57 tons ha-1, and is recommended for cultivation in the North and Northwest regions of the Rio de Janeiro State.
