Problems solved by technology

Excellent resistance germplasm resources are the material basis for disease-resistant breeding. However, the evaluation criteria for the identification of triticale resistance to yellow dwarf disease and the reports of related resistance identification have not been found so far at home and abroad. Therefore, the establishment of triticale resistance The identification method of yellow dwarf germplasm resources is of great significance for the screening of triticale germplasm resources resistant to yellow dwarf disease and the research of resistance breeding

Embodiment 1

[0020] Triticale is to yellow dwarf disease resistance identification method, carries out yellow dwarf disease resistance identification test to the collected 25 triticale varieties, carries out as follows:

[0021] 1. Planting triticale wheat seedlings in arched sheds: choose a sunny and sheltered place in the field, with an area of ​​about 8m2, and moderate soil water and fertilizer conditions. Sow 10 rows of susceptible triticale variety "Nong 13" every autumn, with a row length of 1m and a row spacing of 30cm. Sow seeds regularly to ensure the continuity of wheat seedlings.

[0022] Planting of identification materials: artificial drilling is carried out at the beginning of April each year, each identification material is sown in one row, the row length is 1m, three repetitions are set, the row spacing is 30 cm, and 100 seeds are sown in each row, and the identification materials are randomly arranged.

[0023] 2. Toxin source collection: Collect plants with typical barley...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of crop resistance breeding, in particular to an identification method for triticale yellow dwarf resistance. Background technique [0002] Triticale ( Triticale hexaploide L.), is derived from the Triticum genus ( Triticum aestivum L.) and L. ( Secale cereale L.) A new species that is artificially combined by sexual hybridization between genera and doubling of the number of hybrid chromosomes. The octoploid triticale bred in my country in the 1970s is characterized by not only showing the high yield of wheat and the excellent quality of seeds, but also maintaining the strong stress resistance and high lysine of rye, and being able to adapt to different Climate and environmental conditions, is a promising grain and feed crops. The total planting area of ​​triticale in China has reached 150,000 hectares 2 The above are mainly concentrated in the northwest and southwest mountainous areas of my country....
