“…The use of this tool is recommended, especially when a large number of genotypes are evaluated in a breeding program. In P. notatum, as well as in wheat (Bertan et al, 2006), the selection index based on the ideotype can be used as an auxiliary analysis for genetic distance studies, increasing the efficiency in the choice of parents for future crossings (Silveira and Machado, 2020).…”

“…Therefore, a genotype of high industrial quality is characterized by having grains larger than 2 mm, ease of peeling, and high hectoliter weight (Hawerroth et al., 2015). To select these characteristics, the agronomic ideotype is used, which allows the use of direct and less empirical strategies, obtaining superior genotypes (Silva et al., 2020). There are many advantages as they bring together specific characteristics, pressures, and trends determined by the breeder who seeks to enhance quality, response to management, tolerance to environmental stress, and diseases.…”

“…There are many advantages as they bring together specific characteristics, pressures, and trends determined by the breeder who seeks to enhance quality, response to management, tolerance to environmental stress, and diseases. Some characters are essential for defining a good genotype that meets the agronomic ideotype, with erect growth, reduced stature, stem tolerant to lodging, early cycle, disease tolerance, leaves at the correct angles, compact panicles, high grain weight per panicle, grains larger than 2 mm in diameter, and easy to peel (Silva et al, 2020).…”

This work aimed to propose multivariate selection strategies reconciling the agronomic ideotype and vegetation indices to obtain genotypes with high tillering, early cycle, tolerant to lodging, and foliar diseases. The sowing of white oat lines was carried out on April 27, 2023, allocated in an experimental design of blocks augmented with interspersed controls. The regular treatments correspond to 593 lines of white oat and the common treatments were represented by the cultivars URS Olada, URS Altaneira, and IPR Artêmis arranged in four replications. The measurements of variables of agronomic interest took place in each experimental unit as follows: percentage of tillering, days to flowering, percentage of lodging, percentage of leaf rust, percentage of stem rust, and percentage of leaf spots. The phenomic analyses took place through flights carried out with a specialized drone, equipped with a 20 MP resolution camera and standard height (80 m). The best proposed indices were index for reducing the percentage of lodging with normalized green (NG), green–red ratio (IGR), soil color index (SCI), green leaf index (GLI), visible atmospheric resistant index (VARI), green leaf index 2 (GLI2), red–blue (RB), blue green pigment (BGI), normalized red–blue difference index (NRBDI), green–blue ratio, BIM, normalized green–blue difference index (NGBDI), and ExGR; index for reducing days to flowering with brightness index (BI), NRBDI, days to flowering (DF), gray (GRAY), IGR, average intensity (L), normalized red (NR), RGRI, SCI, BGI, BIM, GLI, NGBDI, and NG; and index for reducing the percentage of stem rust with NG, BI, Gray2, GLI2, RGRI, GLI, VARI, BGI, L, NR, RB, and coloration index. Only two lines were selected concomitantly with multivariate indices, line L167 (M5, SA) and L426 (M6, ETMS), that combine lodging tolerance and leaf rust genes.

“…Currently, the crop is the fifth most cultivated cereal in Brazil, with approximately 503,000 ha sown in 2021, production of 114,300,200 t of grains and productivity of 2271 kg ha −1 of grains (Conab—Companhia Nacional de Abastecimento, 2022). In Brazil, white oats are cultivated in the Southeast, South, and part of the Midwest regions; this is due to the wide adaptation of the crop to the most varied agricultural and environmental scenarios (Silva et al., 2020).…”

“…The advancement of genetic improvement programs in Brazil sought to develop genotypes with high grain productivity and industrial quality, adapted to environmental conditions and more sustainable management (Hawerroth et al., 2014; Silva et al., 2020). The agronomic potential is related to the genetic characteristics of the genotypes and their correct positioning in the growing environments.…”

White oat (Avena sativa L.) is a cold season grass, with a very important role, both in animal and human food, due to the chemical composition of its grains, which have, among other beneficial components, fiber soluble food products, beta‐glucans. Therefore, the demand for grains of the crop is maximized and it is important to increase grain production. This can be achieved through the adequate positioning of the genotypes in the growing environments to maximize the agronomic performance of the crop. Thus, the objective of this work was to decompose meteorological and geographic variables in the positioning of white oat genotypes. The study took place considering 39 genotypes of white oats in 21 environments (in 13 years), in six municipalities of Rio Grande do Sul, two locations in the state of Santa Catarina, ten in Paraná and three municipalities in the state of São Paulo. The average grain yield (kg ha−1) of the genotypes in each environment was used to determine the adaptability and stability of the genotypes through the application of the Genotype and Genotypes by Environments Interaction (GGE biplot) biometric method and the reaction norm. The reaction norm pointed out that the genotypes UPFPS Farroupilha, UPFA Gaudéria and URS Guará demonstrated general adaptability to all environments, while FAEM 006 and URS Charrua expressed stability, high grain yield and higher than average genetic value. The GGE biplot graphically demonstrated that the genotypes URS Monarca and IPR Artemis demonstrated the highest grain yield and high stability in the environments Eldorado do Sul ‐ RS (E7) and Pelotas ‐ RS. Identifying genotypes with superior agronomic performance in specific environments minimizes the effects of genotype x environment interaction. These white oat genotypes can be used as sources of alleles for the development of new genotypes.This article is protected by copyright. All rights reserved
