Embodiment

[0030] A method for hybrid breeding of common wheat and Thiopyrum cerevisiae, comprising the following steps:

[0031] 1) F 0 Generation hybrid seed; F 0 'generation hybrid seed;

[0032] 2) Take 100 parts of local soil, 20 parts of humus soil, 0.2 part of carbendazim, 0.1 part of potassium phosphate, 0.2 part of urea, and 30 parts of sandy soil by weight and mix evenly to obtain the germination matrix; Sprinkle water to infiltrate the entire germination bed after the pottery germination bed;

[0033] 3) Preparation of soaking solution: The concentration of each component in the soaking solution is: indole acetic acid 100mg / L, humic acid 100mg / L, gibberellin 200mg / L, sorbamide quaternary ammonium salt 75mg / L, cinnamamide 75mg / L L;

[0034] 4) Take the F obtained by hybridization in step 1) 0 Hybrid Kernel and F 0 'For hybrid seeds, soak the two kinds of seeds in 0.5% sodium hypochlorite solution at 8-10°C for 15-20 minutes. ) in the soaking solution prepared by soaking ...

Abstract

The invention relates to the technical field of hybrid breeding, in particular to a hybrid breeding method of common wheat and agropyron glaucum. By the hybrid breeding method, with octoploid trititrigia 5 as a bridge, hybrid breeding of the common wheat and the agropyron glaucum is achieved, and in the breeding process, special germination accelerating pretreatment is performed on F0-generation hybrid seeds and F0'-generation hybrid seeds to improve the germination rate thereof; F1-generation parent plants and F1'-generation parent plants are cut for different times to prolong the growth period of the parents, and in the development process of the parents, the own seed setting rate thereof is improved; after cross pollination, a growth-promoting agent is sprayed immediately to further increase the seed setting rate; furthermore, JiMai 22 is selected as a common wheat variety, and a novel wheat variety with high yield, disease resistance, lodging resistance, infertility resistance and drought resistance is bred.

Description

technical field [0001] The invention relates to the technical field of hybrid breeding, in particular to a method for hybrid breeding of common wheat and Henropyrum cerevisiae. Background technique [0002] Thinopyrum is a wild perennial arbor. It has a well-developed root system, strong regeneration ability, drought resistance, barren resistance and cold resistance, high resistance to various diseases, immunity to three rusts on bars, leaves, stems, white powder, and smut. Scab has strong disease resistance, high resistance to yellow dwarf, cong dwarf, yellow leaves, root rot and leaf blight. Many of these properties are not available in ordinary wheat. If the gene of Thinopyrum ceruleus is introduced into common wheat, it will be of great significance to improve the properties of common wheat varieties such as disease resistance, lodging resistance and barren resistance. Therefore, researches have been carried out on the cross breeding of common wheat and Thiopyrum cerevi...
