Embodiment Construction

[0029] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but do not limit the present invention in any way.

[0030] 1. Breaking of wheat seed dormancy

[0031] Through further tests and comparisons based on previous methods, 0.01% gibberellin (GA 3 ) Soak for 12 hours, rinse with clean water, dry (until there is no obvious moisture on the surface) and sow in time, the germination rate can reach about 90%.

[0032] 2. Vernalization

[0033] For vernalization of strong winter wheat, the following methods can be adopted (the time of semi-winter wheat under low temperature treatment of strong winter wheat is reduced to 10 days, and spring wheat can be sown directly after breaking dormancy without vernalization):

[0034] 1. Plant the wheat seeds that break dormancy in a seedling tray, and place them in a vernalization chamber after germination; if there is no vernalization chamber condition, you can plant the do...

Abstract

The invention discloses a Xundian county wheat summer planting generation-adding method which belongs to the technical field of wheat summer planting generation adding. Optimal dormancy breaking methods, vernalization conditions, seedtime and field management modes of different winter and spring wheats are researched, thereby a complete set of wheat summer planting technical system is established, theoretical and technical supports are provided for summer planting generation adding of nationwide wheat heredity and breeding and Yunnan province wheat parent and elite seed expanding propagation, the improvement of food security of China is facilitated, and the social harmony and stability and rural economic development are promoted. By means of the method, the wheat summer planting generation adding can be well achieved in Xundian county.

Description

technical field [0001] The invention belongs to the technical field of summer multiplication and generation of wheat, in particular to a method for summer multiplication and generation of Xundian wheat. Background technique [0002] Conventional hybrid breeding is currently the most important and effective way to cultivate new wheat varieties. However, conventional breeding requires 8-10 years, and the breeding period is too long. In order to solve this problem, in the process of wheat breeding, breeders, according to the physiological and ecological characteristics of wheat, make full use of resources such as natural temperature and light or through artificial adjustment of temperature and light to change the cultivation conditions, so that the vegetative growth can quickly turn to reproductive growth. Transformation, shorten the growth and development period from sowing to maturity, and accelerate the generation process, thereby greatly shortening the breeding period. To ...
