Abstract:    Traditional peach production regions provide adequate chill for satisfactorily bud’s flower break dormancy, in cultivars there developed. However, considering the expansion of the orchards in mild winter areas and the expected global trends to warmer conditions, the local development of cultivars became relevant. Based on this background, this study proposed to evaluate the performance of 33 peach and nectarine cultivars and selections in mild winter climate. Features associated to the vegetative development, phenology, productivity and fruit characteristics were measured in nine seasons, and the data analyzed by multivariate analysis of variance. Significant correlations between features were remarked. The Pillai and F tests presented significant results, highlighting significant differences among cultivars for almost all features. Peach and nectarine genotypes showed genetic diversity that may be accessed for use as cultivars, or parental for crosses. ‘IAC Aurora 1’, ‘IAC Aurora 2’, ‘IAC Centenário’, ‘IAC Douradão’, ‘IAC Jóia4’, ‘IAC Ouromel 3’, ‘IAC Régis’, ‘Diamante’, ‘Eldorado’, ‘FlordaPrince’, ‘Premier’ and ‘Tropic Beauty’ were the cultivars with the best results. A large number of selections showed promising results, emphasizing, the ‘IAC 680-177’, ‘IAC 1085-27’, ‘IAC 785-9’, ‘IAC 2982-31’, ‘IAC 4682-45’and ‘IAC 6882-84’.

Resumo:    As regiões tradicionais de produção de pêssego apresentam frio adequado para a quebra de dormência das gemas de forma satisfatória, nas cultivares localmente desenvolvidas. No entanto, considerando a expansão dos pomares em áreas de inverno ameno e as tendências globais esperadas para condições mais quentes, o desenvolvimento local de cultivares tornou-se relevante. Com base nisso, este estudo propôs-se a avaliar o desempenho de 33 cultivares e seleções de pessegueiro e nectarineira em clima de inverno ameno. Características associadas ao desenvolvimento vegetativo, fenologia, produtividade e características dos frutos foram medidas em nove safras; e os dados, analisados por análise de variância multivariada. Foram observadas correlações significativas entre as características. Os testes de Pillai e F apresentaram resultados significativos, destacando a presença de diferenças entre cultivares para quase todas as características. Os genótipos de pessegueiro e de nectarineira apresentaram diversidade genética que pode ser acessada para uso como cultivares, ou parentais para cruzamentos. As cultivares ‘IAC Aurora 1’, ‘IAC Aurora 2’, ‘IAC Centenário’, ‘IAC Douradão’, ‘IAC Jóia4’, ‘IAC Ouromel 3’, ‘IAC Régis’, ‘Diamante’, ‘Eldorado’, ‘FlordaPrince’, ‘Premier’ e ‘Tropic Beauty’ apresentaram os melhores resultados. Um grande número de seleções apresentou resultados promissores, destacando-se ‘IAC 680-177’, ‘IAC 1085-27’, ‘IAC 785-9’, ‘IAC 2982-31’, ‘IAC 4682-45’ e ‘IAC 6882-84’.
