Research. Inheritance of Resistance to Tomato Yellow Leaf Curl Virus (TYLCV) in Lycopersicon pimpinellifolium. M. A. Kasrawi, Faculty of Agriculture, University of Jordan, Amman. . Plant Dis. 73:435-437. Accepted for publication 20 October 1988. Copyright 1989 The American Phytopathological Society. DOI: 10.1094/PD-73-0435. The inheritance of resistance in Lycopersicon pimpinellifolium to tomato yellow leaf curl virus (TYLCV) was studied in progenies derived from crosses between the resistant parents L. pimpinellifolium Hirsute-INRA and LA 1478 and the susceptible parent L. esculentum ‘Special Back’. Resistance appeared to be stable in these parents. Field-grown seedlings were subjected to natural infection with the tomato yellow leaf curl virus. Analysis of F1, F2, and backcross populations from crosses of L. pimpinellifolium with the susceptible cultivar revealed that resistance is controlled by a single dominant gene. It is suggested that the symbol Tylc be assigned for this gene in L. pimpinellifolium. Keyword(s): disease resistance. |
