Comparison of methods for estimation of chilling and heat requirements of nectarine and peach genotypes for flowering
Maulión, Evangelina; Valentini, Gabriel Hugo; Kovalevski, Leandro; Prunello, Marcos; Monti, Laura Lucía; Daorden, Maria Elena; Quaglino, Marta; Cervigni, Gerardo Domingo Lucio (Elsevier, 2014-10-02)Chilling and heat requirements for breaking dormancy and flowering were studied in 63 nectarine and 118 peach genotypes (Prunus persica (L.) Batsch) for seven years. We compared two methods for estimation of requirements ... -
Germinacion in vitro de embriones inmaduros a distintas temperaturas de estratificacion
Daorden, Maria Elena; Marín, Juan Antonio; Arbeola, Arancha (Asociación Interprofesional para el Desarrollo Agrario, 2002)En los programas de mejora de especies frutales adquiere gran importancia la reducción del tiempo para la obtención de una nueva generación. La estratificación y germinación in vitro de los embriones inmaduros permite ... -
Identification of peach accessions stability and adaptability in non-balanced trials through years
Maulion, Evangelina; Arroyo, Luis Enrique; Daorden, Maria Elena; Valentini, Gabriel Hugo; Cervigni, Gerardo Domingo Lucio (2016)Identification of genotypes with acceptable yield and yield stability in different environments is an important issue in plant breeding. Genotype-by-environment interaction (GEI) can alter genotypes performances making the ... -
Performance profiling of Prunus persica (L.) Batsch collection and comprehensive association among fruit quality, agronomic and phenological traits
Maulion, Evangelina; Arroyo, Luis Enrique; Daorden, Maria Elena; Valentini, Gabriel Hugo; Cervigni, Gerardo Domingo Lucio (2016-01-01)Nowadays, although there are several studies based on peach phenotypic diversity and adaptability,there is no current research regarding associations among characters using multivariate statistical meth-ods which provide ... -
Significant effect of accidental pollinations on the progeny of low setting Prunus interspecific crosses
Arbeola, Arancha; Daorden, Maria Elena; García, Elena; Wünsch, Ana; Hormaza, José Ignacio; Marin, Juan Antonio (Springer, 2006)The incidence of fortuitous pollination on interspecific hybridizations of the plum rootstock Myrobalan with the apricot cultivars ‘Moniquí’ and ‘Moniquí Borde’ was assessed in this work. Progeny was originated through ... -
Stratification temperature affects the In Vitro germination of immature Prunus embryos
Daorden, Maria Elena; Marin, Juan Antonio; Arbeloa, Arancha (ISHS, 2004)The rapid multiplication of clonal plants is desirable to shorten crossing programs in fruit tree breeding. In vitro stratification and germination allowed us to shorten the time and to improve the germination rates by ... -
Study of statistic stability to select high-yielding and stable peach genotypes
Maulión, Evangelina; Valentini, Gabriel Hugo; Ornella, Leonardo Alfredo; Pairoba, Claudio Fabián; Daorden, Maria Elena; Cervigni, Gerardo Domingo Lucio (Elsevier, 2014-08-15)In peach breeding, suitable identification methods for performance stability studies as well as the associations between stability parameters are poorly understood. Therefore, the aims of this work were to compare parametric ...
