Common names

Language	Name	Alternate name	note	seq	Citation
English	Carrizo citrange		as ×Citroncirus webberi	1	Ruiz, 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
