Narrative
This is a seedling selection of a tree derived from PI 29160. Initially introduced as RSD 1997009. Of 30 seeds of RSD 1997090 received, 27 germinated. A nucellar seedling was identified using ISSR markers (RSD1997009SG25 = RRUT 481) and retained as RRUT 481. RSD 1997009 was then inactivated. ISSR markers for RRUT 481 were different than 'Carrizo' citrange, PI 150916.

WT Swingle, (USDA Bureau of Plant Industry, 1910, p 41) characterizes this accession thusly: ""This is a hybrid between the common orange and the trifoliata, having the same parents as the Colman, Morton, and other standard citranges. So far it has borne almost no fruit. On the other hand, it flowers profusely in early spring and the flowers are very large in size, larger than those of either parent. They appear with the leaves and are often so abundant as almost to hide the foliage. This variety is being distributed on a small scale for trial in cities for dooryard planting, where an ornamental rather thanafruittreeisdesired." Remember, he was wrigint this in 1910.

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

Pedigree
Description:
Original cross given in USDA-Bureau of Plant Industry (1910) is "Citrus trifoliata X aurantium" which in modern (GRIN) taxonomy would be Poncirus trifoliata X Citrus sinensis. Nucellar seedling selected with ISSR markers (see Narrative).
