D.Q. Fang and M.L. Roose (1999)
A novel gene conferring Citrus tristeza virus resistance in Citrus maxima (Burm.) Merrill
HortScience 34 (2), 334-335
Abstract: 'Chandler' pummelo [Citrus maxima (Burm.) Merrill] was found to be citrus tristeza virus (CTV)-resistant. The inheritance of this resistance in 84 progeny of two crosses derived from 'Chandler' pummelo and trifoliate orange [Poncirus trifoliata (L.) Raf.] was controlled by a single dominant gene designated Ctv2. Progeny analysis of four molecular markers closely linked to the Ctv gene, which confers resistance to CTV in trifoliate orange, demonstrated that Ctv2 was an independently assorting gene from Ctv.
