Abstract
A study was carried out on the linkage relationship between the Frl lo cus carrying resistance to Fusarium oxysporum f.sp. radicis-lycopersic i and the Tm-2 locus carrying resistance to several races of tobacco m osaic virus in the tomato inbred line IRB-301-31. The inbred line Mote lle (Frl(+)/Frl(+), Tm-2(+)/Tm-2(+)) was crossed with the inbred line IRB-301-31 (Frl/Frl, Tm-2/Tm-2). The resulting 222 F-2 plants were sel fed, and from each F-3 family groups of 15-60 seedlings were tested fo r resistance to either F. oxysporum f.sp. radicis-lycopersici or tobac co mosaic virus race O. Segregation data indicated a very tight linkag e between Frl and Tm-2, equal to 5.1 +/- 1.07 map units.
