[0023] The breeding material Wheat Lankao 52-54 with dwarf stalk, large panicle, multiple grains and disease resistance was used as the male parent and the Taigu nuclear sterile material wheat 0308 bred by Shanxi Gao Zhongli was used as the female parent, and then the hybrid offspring F1 Backcross with the male parent Wheat Lankao 52-54, select sterile plants from the backcross progeny, and then backcross with the male parent Wheat Lankao 52-54, backcross 3 times in this way, and fertilize in a timely manner throughout the growth and development period. Watering, weeding, pest control. After 5 years of breeding, a sterile material similar in shape to Wheat Lankao 52-54 has been bred. Its characteristics are common hexaploid wheat, dwarf stalk, large ears, multiple grains, and disease resistance. After planting, 50% of them will be produced every year sterile and 50% fertile.

Abstract

The invention relates to methods for breeding the breeding materials of wheat and triticale. The method for breeding the wheat comprises the following steps: the new wheat idioplasm Lankao 52-54 is selected as a male parent, and wheat 0308 is selected as a female parent, and the male parent and the female parent are hybridized; and a filial generation and the male parent are carried out repeated backcrossing. The method for breeding the triticale comprises the following steps: No.8 triticale Lankao is selected as a male parent, the wheat 0308 is selected as a female parent, and the male parent and the female parent are hybridized; and a filial generation and the male parent are carried out repeated backcrossing. The wheat and the triticale which are bred by the invention have compatible hybridization with mediterranean agropyron and are easy to fruit; the excellent characteristics of the mediterranean agropyron can be inherited; and a plurality of new types and species of ice wheat and ice triticale can be bred.

Description

technical field [0001] The invention relates to a crop production method, in particular to a wheat and triticale cultivation method. Background technique [0002] Wheat is not only the world's largest food crop, but also an important raw material for animal husbandry and industry. In view of the basic national conditions of our country with more people and less land, the only way to produce high-quality and high-yield wheat is to rely on science and technology to increase the yield per unit area of ​​wheat, improve quality, enhance resistance, and increase its wide adaptability. [0003] For a long time, the improvement of wheat varieties has mostly relied on hybridization within varieties, but the hybridization within varieties has close kinship, germplasm resources are scarce, and the breakthrough types of offspring are few, so the probability of breeding excellent wheat varieties is low. Therefore, many breeders are committed to adopting the method of distant hybridizati...
