Citrus trees are subject to several abiotic constraints such as salinity. Providing new rootstocks more tolerant is thus a requirement. In this article, we investigated salt stress tolerance of three tetraploid rootstock genotypes when compared to their respective diploid rootstocks (Poncirus trifoliata, Carrizo citrange, Cleopatra mandarin). Plant growth,(More)
The sequence-tagged microsatellite site (STMS) discrimination potential was explored using nine microsatellite primer pairs. STMS polymorphism was assayed by nonradioactive urea-polyacrylamide gel electrophoresis. Genetic relationships were examined among 59 genotypes of wild or cultivated accessions of diploid Musa acuminata. The organization of the(More)
Liquid medium improves and facilitates somatic embryo development from Citrus deliciosa Ten. suspension cultures. Three different culture conditions were compared to determine a means of overcoming poor somatic embryo development. Somatic embryos derived from suspension cultures were plated on solid medium, maintained in suspension culture or temporarily(More)
This study focused on haploid induction in mandarin through in situ gynogenesis by pollination with irradiated pollen of ‘Meyer’ lemon. Pollination was carried out for three genotypes of mandarin with four levels of gamma-ray-irradiated pollen (150, 300, 600, and 900 Gy). The resulting seeds were characterised by a small size. Embryos were rescued in vitro(More)
Utilization of existing isozyme analysis facilities to detect sequence-tagged microsatellite site (STMS) polymorphism or any simple sequence repeat (SSR) variation is described. Different parameters concerning the difficulties in transferring molecular techniques to less sophisticated laboratory infrastructures (i.e. tropical outstations) are discussed(More)
A dinucleotide-enriched genomic library was obtained from mandarin orange (Citrus reticulata Blanco). A subset of 101 positive clones was sequenced and primers were designed. The loci were screened for levels of variation using 26-29 wild mandarin oranges collected in Vietnam. Forty-three loci were polymorphic with the number of alleles ranging from two to(More)
Musa species are among the tallest monocotyledons and include major food-producing species. The principal cultivars, derived from two major species Musa acuminata (‘A’ genome) and Musa balbisiana (‘B’ genome), are polyploid hybrids (mainly AAA, AAB and ABB triploids), medium to highly sterile, parthenocarpic and clonally propagated. Bananas and plantains(More)
The prevalence of sour orange rootstock in the southern and eastern part of the Mediterranean Basin is presently threatened by the spread of Citrus Tristeza Virus (CTV) and its main vector Toxoptera citricida, combined with abiotic constraints such as drought, salinity and alkalinity. The search for alternative CTV-resistant rootstocks that also withstand(More)
The main components of citrus fruit quality (organic acids, sugars, and aromatic compounds) were studied in fruits of a somatic hybrid allotetraploid between Willow leaf mandarin (Citrus deliciosa Ten.) + Eureka lemon [Citrus limon (L.) Burm.] and the two diploid parents. The somatic hybrid (WLM + EUR) combined both nuclear genomes of the parents, with(More)
