The location of major quantitative trait loci (QTL) contributing to stem and leaf [Na(+) ] and [K(+) ] was previously reported in chromosome 7 using two connected populations of recombinant inbred lines (RILs) of tomato. HKT1;1 and HKT1;2, two tomato Na(+) -selective class I-HKT transporters, were found to be closely linked, where the maximum logarithm of(More)
Two complex populations derived from the salt-tolerant citrus rootstock Cleopatra mandarin were used to investigate (1) the genomic regions affected by segregation distortion and (2) gene segregation heterogeneity and their causes and to obtain (3) a Citrus reshni linkage map to genetically analyze (4) the duration of the juvenility period and the seed(More)
Rootstock HKT1 genotype affected fruit [Na + ] and non-commercial fruit yield; QTL analysis of rootstock-mediated scion nutrition is a powerful forward genetic approach to identify wild genes for rootstock breeding. The present study approaches the QTL dissection of rootstock effects on a commercial hybrid variety grafted on a population of RILs derived(More)
To extend the harvesting period of high quality seedless fruits in citrus variety breeding programs, 20 traits related to vegetative growth (2), sexual reproduction (5), and fruit quality (13) were genetically studied in a segregating population of hybrids derived from a reciprocal cross between two commercial varieties, Fortune (a Citrus clementina hybrid)(More)
A total of 60 traits that could be related to salt tolerance were genetically analyzed using nucellar plants as repetitions of apomictic hybrids in a reference population derived from two common citrus rootstocks, Cleopatra mandarin (salt tolerant) and trifoliate orange (salt sensitive), in two experiments differing in duration (1 versus 3 years) [NaCl] (30(More)
