The objective of this study was to evaluate the physiological quality of seeds from early and late maturing Coffea canephora
clones, aiming to identify the ideal harvest time. The fruits were collected every two weeks from 188 days after anthesis (DAA) and
characterized as green, cane green, cherry, and dry. The seeds were evaluated for water content, germination percentage, normal and
abnormal seedlings, nongerminated seeds and dead seeds, vigor index, hypocotyl, and root length. Seed germination of the early maturing
clone started at 202 DAA, while that of the late maturing clone started at 230 DAA, with both clones showing a water content of 63% and a
dry mass of 37%. Although the optimum harvest point was identified at the cherry ripening stage, it was found that the late maturing clone
showed a more pronounced variation in the maturation process, directly impacting the physiological quality of the seeds. Furthermore,
a significant correlation was observed between the maturation stages and the physiological quality of the seeds. For the early maturing
clone, the maximum physiological quality was recorded at 244 DAA, corresponding to 80% of fruits at the cherry stage, while for the late
maturing clone this point was reached at 326 DAA, with 98% of the fruits ripe. |

Maize (Zea mays L.) is widely cultivated worldwide and in Brazil under different production systems and technology levels. However, the interaction with different environments may hinder an accurate indication of maize genotypes. The effects of the genotype × environment (G × E) interaction and the stability parameters must be considered to indicate responsive genotypes for the different cultivation regions. Thirteen maize varieties, including nine traditional (farmer-led selection and adaptation) and four commercial (bred and produced for specific markets through formal breeding programs) varieties, were evaluated in nine environments in EspÃÂrito Santo, Brazil, to study G × E interaction, identify adaptable and stable materials, and explore variability through genetic resources, using a randomized block design with three replications. Adaptability and stability parameters were tested using five different methodologies. The variety Aliança approached the level considered as broad adaptability. Environments 5, 6, 7, and 9 were classified as unfavorable. The varieties Alfredo Chaves, Catete and Catetim showed good stability indexes, with an average productivity of 5870.36, 5259.27 and 4914.20 kg/ha, respectively. Our findings will allow the exploration of the variability and genetic resources of some important materials, providing potential for gains in genetic breeding.
O milho (Zea mays L.) é amplamente cultivado no mundo e no Brasil sob diferentes sistemas de produção e nÃÂveis tecnológicos. Porém, a interação com diferentes ambientes pode dificultar uma indicação precisa dos genótipos de milho. Os efeitos da interação genótipo × ambiente (G × E) e dos parâmetros de estabilidade devem ser considerados para indicar genótipos responsivos para as diferentes regiões de cultivo. Treze variedades de milho, incluindo nove variedades tradicionais (seleção e adaptação lideradas pelo agricultor) e quatro variedades comerciais (criadas e produzidas para mercados especÃÂficos por meio de programas formais de melhoramento genético), foram avaliadas em nove ambientes no EspÃÂrito Santo, Brasil, para estudar a interação G × E, identificar materiais adaptáveis e estáveis e explorar a variabilidade por meio de recursos genéticos, utilizando delineamento em blocos casualizados com três repetições. Os parâmetros de adaptabilidade e estabilidade foram testados utilizando cinco metodologias diferentes. A variedade Aliança aproximou-se do nÃÂvel considerado de ampla adaptabilidade. Os ambientes 5, 6, 7 e 9 foram classificados como desfavoráveis. As variedades Alfredo Chaves, Catete e Catetim apresentaram bons ÃÂndices de estabilidade, com produtividade média de 5.870,36, 5.259,27 e 4.914,20 kg/ha, respectivamente. Nossas descobertas permitirão a exploração da variabilidade e dos recursos genéticos de alguns materiais importantes, proporcionando potencial para ganhos no melhoramento genético.
