Linkage Characterization of Resistance to Zymv and Wmv-2 in the Inbred Chinese Cucumber Line Tmg-1
Year: 1992
Type: article
Abstract: TMG-1 is resistant to ZYMV and WMV-2, two closely related potyviruses. Resistance to ZYMV is due to a single recessive gene (Provvidenti, 1987); however, two recessive genes appear to confer resistance to WMV-2. We sought to further characterize the resistances by studying possible linkage relationships with physiological, morphological, electromorphic, and phytopathological markers. TMG-1, WI-2757 (an inbred line susceptible to both viruses), and their F 2 progeny were screened for various single gene characters that differ between the two parents. Linkages reported in the literature were also observed in this study: (1) between bitterfree ( bi ) and female ( F ), and (2) between numerous spine ( ns ), small spine ( ss ), and tuberculate ( Tu ). New linkages detected were between: (1) resistance to WMV-2 and F , (2) resistance to WMV-2 and ZYMV, and (3) possibly resistance to ZYMV with fusarium and ns .
