ABSTRACT - The objective of this work was to select cowpea lines with compound inflorescences that show a high potential to generate the first commercial cultivar with this characteristic in Brazil. Thirty-seven lines were evaluated in a randomized complete block design, with two replicates, in 2021, in the municipality of Teresina, in the state of Piauí. The following traits were evaluated: number of days to the onset of flowering, plant size, commercial grain quality, number of grains per pod, weight of 100 grains, and grain yield. Deviance analyzes were performed by the restricted maximum likelihood/best unbiased linear predictor methodology, and the values and genetic parameters necessary to carry out simultaneous selection were estimated based on the rank sum index. A statistical difference was detected between the lines evaluated by the likelihood ratio test (LRT). In general, genetic variance was the largest component of phenotypic variance for the evaluated traits. The ten most promising cowpea lines with compound inflorescences are: MNC15-33E-123, MNC15-33E-178, MNC15-33E-222, MNC15-33E-171, MNC15-33E-232, MNC15-33E-223, MNC15-33E-219, MNC15-33E-183, MNC15-33E-91, and MNC15-33E-165. These lines were selected for the next selection stages and show a high potential to generate the first commercial cowpea cultivar with compound inflorescences in Brazil.
RESUMO - O objetivo deste trabalho foi selecionar linhagens de feijão-caupi de inflorescência composta que apresentam alto potencial para gerar a primeira cultivar comercial com esta característica no Brasil. Trinta e sete linhagens foram avaliadas em delineamento de blocos ao acaso, com duas repetições, em 2021, no município de Teresina, no estado do Piauí. Foram avaliados os seguintes caracteres: número de dias para o início do florescimento, porte da planta, qualidade comercial do grão, número de grãos por vagem, peso de 100 grãos e rendimento de grãos. Foram realizadas análises de deviance pela metodologia da máxima verossimilhança restrita/melhor preditor linear não viesado, e estimados os valores e os parâmetros genéticos necessários para realização da seleção simultânea com base no índice de soma de postos. Foi detectada diferença estatística entre as linhagens avaliadas por meio do teste de razão de verossimilhança. Em geral, a variância genética foi o maior componente da variância fenotípica para os caracteres avaliados. As dez linhagens de feijão-caupi de inflorescência composta mais promissoras são: MNC15-33E-123, MNC15-33E-178, MNC15-33E-222, MNC15-33E-171, MNC15-33E-232, MNC15-33E-223, MNC15-33E-219, MNC15-33E-183, MNC15-33E-91 e MNC15-33E-165. Essas linhagens foram selecionadas para as próximas etapas de seleção e apresentam grande potencial para gerar a primeira cultivar comercial de feijão-caupi de inflorescência composta no Brasil.

Florfenicol is one of the most-used antimicrobial agents in global fish farming. Nevertheless, in most countries, its use is not conducted in accordance with good practices. The aim of this work was to evaluate the leaching of florfenicol from coated fish feed into the water. Analytical methods were developed and validated for the quantitation of florfenicol in medicated feed and water by UHPLC-MS/MS. Florfenicol residues in the water were quantified after 5- and 15-min exposures of the medicated feed in the water at 22 and 28°C and at pH 4.5 and 8.0. The influence of pellet size and three coating agents (vegetable oil, carboxymethylcellulose, and low-methoxylated pectin) on the leaching of the drug was also assessed. Pellet size, coating agent, water temperature, and time of exposure significantly (p <0.05) affected florfenicol leaching, while water pH did not interfere with the leaching. Coating with vegetable oil was the most efficient method to reduce florfenicol leaching, while coating with carboxymethylcellulose presented the highest leaching (approximately 60% after 15 min at 28°C). Thus, the coating agent has a significant effect on the florfenicol leaching rate and, consequently, on the necessary dose of the drug to be administered. Moreover, it is worth mentioning that higher florfenicol leaching will pose a greater risk to environmental health, specifically in terms of the development of bacteria resistant to florfenicol. Additional studies are needed with other polymers and veterinary drugs used in medicated feed for fish farming. MenosFlorfenicol is one of the most-used antimicrobial agents in global fish farming.
