Summary
The genetic nature of resistance to four Australian strains of Puccinia recondita was studied in the cultivar Timgalen and in three entries of the 1963 ISWRN, viz, 25 (W3300) 318 (W3301) and 409 (W3303). Seedling resistance of Timgalen was controlled by the dominant gene Lr3 and by a recessive gene, tentatively designated lrT. A third gene, identical with one in C.I.12632, was operating in adult plants only.
In each of the three varieties W3300, W3301, W3303 the same dominant and the same recessive gene were operating in seedlings. The former may be identical with a major gene previously reported in Klein Titan, Frontana and Rio Negro. The latter gene was different from lrT of Timgalen. In addition, W3301 and W3303 each carried a dominant factor being only operative in the mature plant stage.
