The invention discloses a method for identifying the yellow dwarf resistance of
triticale. The method comprises the following steps that 1, the
triticale is sown in ten rows, and an arched shed is subjected to heat preservation; 2, authigenic
triticale seedlings carrying yellow dwarf viruses and plants with yellow dwarf
virus symptoms are transplanted into the arched shed, and the typical
disease plants are inoculated with aphids for expanding propagation; 3,
sowing is carried out, triticale materials are identified, and the materials are sequentially arranged in a field according to identification numbers; 4, when the identified materials are at an elongation stage,
disease leaves of the triticale where the yellow dwarf viruses are subjected to expanding propagation are subjected to
virus feeding with the aphids, and the identified materials are inoculated with the
disease leaves; 5, resistance evaluation is carried out. The method for identifying the yellow dwarf resistance of the triticale is convenient to operate, simple, easy to implement and low in cost, the trouble of indoor storage and
aphid reproduction is saved, the resistance of hundreds of triticale materials to all epidemic strains of the local yellow dwarf viruses can be identified at a time, high pertinency is achieved, the detection efficiency is high, and good accuracy is achieved.
