Narrative
This selection of 'Rusk' is the preferred accession for indexing for Citrus Tatterleaf Virus and should be requested rather than the other 'Rusk' accessions (RCRC 301/PI 13002 and RCRC 1441/PI 539809) if indexing is the intended use. Other characteristics are not well documented but this probably does not differ much from the other accessions. (RRK, 08/2006)

EnglishCarrizo citrange as ×Citroncirus webberi1Ruiz, M. et al. 2018. Molecular characterization and stress tolerance evaluation of new allotetraploid somatic hybrids between Carrizo Citrange and Citrus macophylla W. rootstocks. Front. Plant Sci. 9:901. Note: the Citrus tristeza virus is graft transmissible; 'Carrizo citrange' (Citrus × insitorum (as “C. sinensis × Poncirus trifoliata”)) is the most important graft stock of worldwide use, favoring high yield, fruit quality, and being tolerant to CTV but salt-intolerant; through somatic hybridization with Citrus × aurantiifolia (as C. macrophylla), this study obtained two hybrids; these plants combined the parental alleles, but also this study detected that most lost alleles occurred during the somatic hybridization; physiological tests showed that the somatic hybrids were tolerant to salinity; it recognized the potential of somatic hybrids SMC-58 and SMC-73 as graft stocks for areas with CTV and calcareous and saline soils

Description:
Seedling tree at CCPP Rubidoux greenhouse. Seeds were most probably obtained from one of the existing 'Rusk' accessions at the Citrus Research Center (RCRC 301/PI 13002 or RCRC 1441/PI 539809). However, at this time which of these produced the seeds is not known. These two accessions were introduced at different times from different sources but are most probably identical.
