Resumo: In Brazil, the Plant Variety Protection Law has broadened the conditions for appropriation by institutions that research new plant genotypes. Since then, the use of protected cultivars implies the payment of royalties to their respective breeders. This paper suggests a theoretical model to help estimate the technological evolution of cultivars and its contribution to the collection of royalties. The model was formulated based on meta-analysis data in which it was verified how the royalty rate for protected cultivars is defined and how these could be weighted in the technological evolution model. Definition of variables according to cultivar and production area. Simulations analyzed for farmer's profit. It was verified that homoscedasticity was not necessary for the simple purpose of predicting values through the regression model. However, the Breusch-Pagan and Durbin-Watson tests were performed to check for violation of the residuals.  The estimation of the Technological Evolution of Cultivars (cotton and sugarcane) showed similarities between the agronomic characteristics according to the Wilcoxon test. Considering the technological evolution of each cultivar the correction equation was proposed to the royalties charged on cotton cultivars.The correction equation was proposed to the royalties charged on sugarcane cultivars. The linear regression model ratified the use of the correction model that may be used in the valuation of royalties and that may help in the identification of the technological evolution of cultivars.

A partir de entonces, el uso de cultivares protegidos implica el pago de derechos a sus respectivos obtentores. El presente artículo propone un modelo teórico para ayudar a estimar la evolución tecnológica de los cultivares y su contribución a la recaudación de derechos. El modelo se formuló a partir de datos de meta-análisis en los que se comprobó cómo se define la tasa de regalías para los cultivares protegidos y cómo se pueden ponderar en el modelo de evolución tecnológica. Definición de las variables según el cultivar y la zona de producción. Simulaciones analizadas para el beneficio del agricultor. Se verificó que la homocedasticidad no era necesaria para el simple propósito de predecir valores a través del modelo de regresión. Sin embargo, se realizaron las pruebas de Breusch-Pagan y Durbin-Watson para comprobar la violación de los residuos.  La estimación de la Evolución Tecnológica de los Cultivos (algodón y caña de azúcar) mostró similitudes entre las características agronómicas según la prueba de Wilcoxon. Teniendo en cuenta la evolución tecnológica de cada cultivar, se propuso la ecuación de corrección de los cánones cobrados por los cultivares de algodón. El modelo de regresión lineal ratificó el uso del modelo de corrección que puede ser utilizado en la valoración de los derechos y que puede ayudar en la identificación de la evolución tecnológica de los cultivares.No Brasil, a Lei de Proteção de Cultivares ampliou as condições de apropriação por parte das instituições que pesquisam novos genótipos vegetais. A partir de então, a utilização de cultivares protegidas implica no pagamento de royalties aos seus respectivos obtentores. O presente artigo sugere um modelo teórico para auxiliar na estimativa da evolução tecnológica de cultivares e sua contribuição para a cobrança de royalties. O modelo foi formulado baseado em dados de meta-análise em que se verificou como se define a taxa dos royalties para as cultivares protegidas e como estes poderiam ser ponderados no modelo de evolução tecnológica. Definição das variáveis de acordo com a cultivar e a área de produção. Simulações analisadas para o lucro do agricultor. Verificou-se que a homoscedasticidade não foi necessária para o simples intuito da previsão de valores através do modelo de regressão. Entretanto, foi feito os teste de Breusch-Pagan e Durbin-Watson para averiguar a violação dos resíduos.  A estimativa da Evolução Tecnológica das Cultivares (algodão e cana-de-açúcar) mostrou semelhanças entre as características agronômicas de acordo com o teste de Wilcoxon. Considerando a evolução tecnológica de cada cultivar a equação de correção foi proposta aos royalties cobrados nas cultivares de algodão. A equação de correção foi proposta aos royalties cobrados nas cultivares de cana-de-açúcar. O modelo de regressão linear ratificou a utilização do modelo de correção que poderá ser usado na valoração de royalties e  que pode auxiliar na identificação da evolução tecnológica das cultivares.Research, Society and Development2022-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3264010.33448/rsd-v11i10.32640Research, Society and Development; Vol. 11 No. 10; e269111032640Research, Society and Development; Vol. 11 Núm. 10; e269111032640Research, Society and Development; v. 11 n. 10; e2691110326402525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/32640/27846Copyright (c) 2022 Eduardo José de Silva; Renata Silva-Mann; Crislaine Costa Calazanshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Eduardo José deSilva-Mann, RenataCalazans, Crislaine Costa 2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/32640Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:34.330691Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
