All the genotypes previously described resistant or tolerant to TEV or PVY appear susceptible to our strain of TEV, except Pl 247087 . This L hirsutum previously reported tolerant to TEV (Hikida and Raymer, 1972) appears to be highly resistant to TEV strain CAA 10 . P1 247087 was also found resistant to two isolates coming from Cuba and one isolate coming from Turkey . This accession is also highly resistant to PVY (Thomas and Mac Grath, 1988 ; Legnani et al, 1996) . The inheritance of its resistance was studied in intraspecific crosses, F 2 (P1 134417 x P1 247087) and BC, (Pl 134417 x P1 247087) x Pl 247087 . Thirty days after inoculation, segregation ratios (31 R:69S in F 2 and 52R:48S in BC,) fitted with the hypothesis of I recessive gene controlling the resistance to TEV in P1 247087, Literature cited: Alexander L .
