Citrus ID, Edition 2, entity 8911, titled “Willowleaf Mandarin,” directly matches this cultivar name. General identification-key description; cites Cottin (2002), Mabberley (1997, 2004), and Swingle & Reece (1967). The key gives variable rind states and is not a single CRC 3843 fruit sample or measured observation. Footer identifies Edition 2, October 2011.

UC ANR article, Publication Number 31-111. The embedded publication note says published December 2004; the webpage displays January 1, 2026. Under “Mandarin Types,” its Mediterranean group is called “Willowleaf” because of narrow leaves. This is a group-level naming explanation, not a CRC 3843 accession description or trial.

Primary study corresponding to the supplied ResearchGate figure page; cite this publisher article rather than a duplicate figure citation. Table 1 identifies the study's Willowleaf parental genotype as Citrus deliciosa, ABS phenotype R, locus genotype aa. The parental genotype was assessed at IVIA orchards in Moncada, Valencia (field observations 2010–2012) and in detached-leaf assays. No accession number or match to UCR CRC 3843 is reported; this is a study-specific phenotype, not a universal resistance claim.

Table 2, printed p. 28, reports counts for seedlings in Substation 15 plots inoculated in 1950: cotton-root-rot deaths in 1951 and 1952, and seedlings alive in September 1952. Counts are not percentages; the table gives no per-row denominator. The paper cautions that freeze injury, other diseases, and planting-date differences complicated comparisons.
