Resistance genes in rye (separate list because of confusion in designation and localization)

Leaf rust (Puccinia recondita f. sp. secalis) is the most relevant windspread disease endemic in all rye-cultivating regions.

var. Chulpan 2 - digenic for  (Lr) brown rust resistance (380)

var. Avangard 2, Novozybkovskaya 4-2, Derzhavinskaya 2 - one dominant gene  for  (Lr) brown rust resistance (380)

Lr436 - in var. Sanim (380,401)

Lr536 - in var. Immunaya 1, Malish 72-2 (380,401)

Lr636 - in var. Chulpan 3-2,  Immunaya 4 (380,401)

Lr736 - in var. Novozybkovskaya 4-2 (380,401)

Lr836 - in var.  Lovazpatonai 2 (380,401)

Lr1036 - in Yaroslavna 3 (401)

Sr1 - dominant oligenic  (Sr) stem rust resistance in var. Rossul, Kharovskaya 55 (380)

Pgs1 - dominant gene stem rust reistance, Puccinia graminis f. sp. secalis (532)

Leaf (brown) rust (Puccinia recondita f. sp. secalis) and powdery mildew  (Erysiphe graminis f. sp. secalis) of rye
