Seven markers linked to QTL involved in CTV accumulation, leafminer resistance and apomictic reproduction were used to characterize 64 sour orange (Citrus aurantium L.) accessions from three national collections in order to identify a representative core in which the resistance behaviour against two Citrus tristeza virus (CTV) isolates was studied. Different degrees of apomixis were found between the foreign collections. Most of the C. aurantium accessions fall into three main groups based on three multilocus genotypes. The haplotype diversity at three CTV accumulation QTL-linked markers was further studied by sequence analysis of alleles. Genotypic and allelic diversity at one of them, tightly linked to Ctv-R 2 in Poncirus trifoliata (L.) Raf., match the plant-CTV interaction types reported among Poncirus and Citrus species. Only those selected accessions from the major group presented CTV resistance during 30 months of continuous growth, but later the resistance broke down in some plants. CTV tolerance appears related to slow growing genotypes. Certain micronutrients: Mn, and B depending on the accession, might play a relevant role in this hostpathogen interaction particularly in alkaline soils.

“…There are several attempts at studying relationships of Citrus species using morphological, physiological, and cytological characters, as well as various isozyme and DNA fingerprints such as restriction fragment length polymorphism (RFLP), random amplified polymorphic DNA (RAPD), simple sequence repeats (SSR) and intersimple sequence repeats (ISSR) (Iwamasa and Nito 1988; Cornélio et al 2003; Mwenje et al 2006). The analysis of enzymatic systems has played an important role in identifying the Citrus species (Grosser et al 1990; Herrero et al 1996; Protopapadakis and Papanikolaou 1999; Mwenje et al 2006). Cytogenetics focusing on variation in chromosome numbers (Iwamasa and Nito 1988) and secondary constriction were used to determine diversity between Citrus and Citrus relatives (Marcelo et al 1997).…”

To effectively conserve sour orange (Citrus aurantium L.) germplasm on two islands at the estuary of the Yangtze River in China, we estimated genetic variation and relationships of the known parental trees and their proposed descendents (young trees) using the fingerprints of random amplified polymorphic DNA (RAPD). Results based on RAPD analyses showed considerable genetic diversity in the parental populations (H e = 0.202). The overall populations including the parental and young trees showed slightly higher genetic diversity (H e = 0.298) than the parents, with about 10% variation between populations. An unweighted pair group method with arithmetic mean analysis dendrogram based on cluster analysis of the Jaccard similarity among individuals demonstrated a more complicated relationship of the parental and young trees from the two islands, although the young trees showed a clear association with parental trees. This indicates a significant contribution of parental trees in establishing the sour orange populations on the two islands. According to farmers' knowledge, conservation of only one or two parental trees would be sufficient because they believed that the whole populations were generated from a single mother tree. However, this study suggests that preserving most parental trees and some selected young trees with distant genetic relationships should be an effective conservation strategy for sour orange germplasm on the two islands.

“…El desarrollo de nuevos portainjertos de cítricos, se centra en reunir el mayor número de características de interés en un solo cultivar. Los inconvenientes que plantea la mejora tradicional de portainjertos mediante hibridación sexual se atribuyen principalmente a la compleja biología reproductiva de los cítricos y a su alta heterozigosidad que hace muy complicado y largo el proceso de obtención y selección de individuos que reúnan los caracteres deseados de ambos parentales (Herrero et al, 1996;Ollitrault et al, 2003;Barkley et al, 2006;Ollitrault y Navarro, 2012).…”

“…Por un lado, su compleja biología reproductiva impide en muchos casos la realización de los cruzamientos deseados debido, fundamentalmente, a la apomixis y a la incompatibilidad sexual existente entre muchos genotipos. Por otro lado, la alta heterozigosidad provoca una gran segregación de caracteres en la progenie, lo que hace muy complicada la obtención y selección de individuos que reúnan los caracteres deseados de ambos parentales (Herrero et al, 1996;Ollitrault et al, 2003;Barkley et al, 2006). La hibridación somática mediante fusión de protoplastos (véase apartado I-3.2.2.1.3) ha permitido, en los últimos años, sortear éstos inconvenientes, incluyendo la obtención de híbridos de especies sexualmente incompatibles (Louzada et al, 1993;Grosser et al, 1996b;Guo y Deng, 1999).…”
