Item Adaptabilidade e estabilidade de genótipos de amendoim de porte rasteiro(2006) Oliveira, Eder Jorge de; Godoy, Ignácio José de; Moraes, Andrea Rocha Almeida de; Martins, Antônio Lúcio Mello; Pereira, José Carlos Vila Nova Alves; Bortoletto, Nelson; Kasai, Francisco SeiitiThe performance of peanut (Arachis hypogaea L.) genotypes was assessed using three different adaptability and stability methods. Eighteen lines and two cultivars, Runner IAC 886 and IAC Caiapó, were evaluated for pod yield (PY) and one hundred kernel weight (HKW), in ten field trials in the State of São Paulo, using ecovalance, Eberhart & Russel and Lin & Binns methods. Significant differences for genotype (G), environment (E) and interaction (GxE) effects were observed for both variables. The lines L123, L137 and L150 were most productive and showed stable and predictable behavior. Lin & Binns methods was more sensitive for PY and HKW, while the Eberhart & Russel method was more useful for indicating lines with broad and specific adaptability to environmental conditions. Moreover, the Lin & Binns and Eberhart & Russel methods were more informative than ecovalance in predicting the behavior of genotypes for those two characteristics. Negative correlation between PY and Pi parameter, and positive correlation between deltaij and omegaI were found. Negative correlation was observed between one HKW and Pi, and between Pi and omegai. O comportamento produtivo de genótipos de amendoim (Arachis hypogaea L.) foi avaliado a partir de três diferentes métodos de adaptabilidade e estabilidade. Foram avaliadas 18 linhagens e as cultivares Runner IAC 886 e IAC Caiapó, quanto à produtividade de vagens (PV) e peso de 100 grãos (P100G), em dez ensaios de campo, no Estado de São Paulo, utilizando-se os métodos de ecovalência, Eberhart & Russel e Lin & Binns. Foram observadas diferenças significativas para o efeito de genótipo (G), ambiente (E) e interação (GxE), para as duas variáveis. As linhagens L123, L137 e L150 foram as mais produtivas, com comportamento estável e previsível. O método de Lin & Binns mostrou-se mais discriminante na avaliação da PV e do P100G, enquanto o método de Eberhart & Russel foi mais útil na indicação das linhagens com adaptabilidade ampla ou específica a determinados ambientes. Os métodos de Lin & Binns e de Eberhart & Russel foram mais informativos que o de ecovalência, na predição do comportamento das linhagens para as duas características. Foi encontrada correlação negativa entre a PV e o parâmetro Pi, e positiva entre deltaij e ômegai. Para P100G, detectaram-se as mesmas correlações de PV, além da correlação negativa entre Pi e ômegai.Item IAC OL 5 - New high oleic runner peanut cultivar(2017) Godoy, Ignácio José de; Santos, João Francisco dos; Michelotto, Marcos Doniseti; Moraes, Andrea Rocha Almeida de; Bolonhezi, Denizart; Freitas, Rogério Soares de; Carvalho, Cassia Regina Limonta de; Finoto, Everton Luis; Martins, Antonio Lúcio MeloAbstract IAC OL 5 is a new peanut cultivar recommended to growers of peanut regions of the state of São Paulo as another option for planting during the intervals of sugarcane renewal. Its main traits are its runner growing habit, its moderate resistance to virus and foliar diseases, and the high oleic trait.Item IAC OL 5 - New high oleic runner peanut cultivar(2017) Godoy, Ignácio José de; Santos, João Francisco dos; Michelotto, Marcos Doniseti; Moraes, Andrea Rocha Almeida de; Bolonhezi, Denizart; Freitas, Rogério Soares de; Carvalho, Cassia Regina Limonta de; Finoto, Everton Luis; Martins, Antonio Lúcio MeloAbstract IAC OL 5 is a new peanut cultivar recommended to growers of peanut regions of the state of São Paulo as another option for planting during the intervals of sugarcane renewal.

In this study, the adaptability and stability parameters were estimated in eight high-oleic lines and two peanut cultivars in 11 experiments in the State of São Paulo, Brazil, from 2008 to 2013, based on the data of the plots mean productivity (Kg·ha–1), with the objective of recommending the most productive genotypes in peanut producing regions in the State of São Paulo. The design used for these experiments was the randomized complete blocks, with four replications. Lines L. 599 and L. 551 were the best genotypes regarding overall adaptability and stability in yield, considering the methods of Eberhart and Russell and of Lin and Binns modified by Carneiro. Results produced by both methods were convergent as for the classification of the lines, and the use of one of them would not be detrimental to the recommendation of productive lines associated to production adaptability and stability. The overall adaptability in addition to the stability in the productivity of the lines here evaluated showed outstanding performance in relation to the cultivars IAC Caiapó and Runner IAC 886.
