Embodiment 1

[0021] A kind of supplementary breeding method applicable to wheat in northern winter wheat region, said method comprises the following steps:

[0022] Step 1: Sow zero-generation seeds of different varieties in the greenhouse on October 1 of the first year, hybridize at the flowering stage, and harvest on May 1 of the second year to obtain the first-generation seeds; then place the first-generation seeds under sunlight Drying, then shelling and drying;

[0023] Step 2: Sow the first-generation seeds in the laboratory on May 21 of the second year, vernalize the seedlings to obtain seedlings, and transplant the seedlings to the greenhouse for growth and cultivation. Harvest on October 1 of the second year to obtain the second generation seed;

[0024] Step 3: sow the second-generation seeds in the field on October 11 of the second year, and select several target plants whose agronomic traits are better than the control plants on June 11 of the third year, and harvest the singl...

Abstract

The invention particularly relates to a generation-adding breeding method suitable for wheat in northern winter wheat areas. The problems that an existing generation-adding breeding method for the wheat in northern winter wheat areas is high in cost and large in loss, and correctness of a breeding direction cannot be guaranteed are solved. The generation-adding breeding method suitable for the wheat in the northern winter wheat areas comprises the following steps that 1, zeroth-generation seeds are sown in a greenhouse in October of the first year, and harvesting is conducted in May of the second year; 2, first-generation seeds are sown in a laboratory in May of the second year, seedlings are transplanted into the greenhouse, and harvesting is conducted in October of the second year; 3, second-generation seeds are sown in a field in October of the second year, and target plants are selected and harvested in June of the third year; 4, third-generation seeds are sown in a laboratory in June of the third year, seedlings are transplanted into the greenhouse, and harvesting is conducted in October of the third year; and 5, fourth-generation seeds are sown in the field in October of thethird year, and harvesting is conducted in June of the fourth year. According to the method, the breeding efficiency is improved, correctness of the breeding direction is ensured to the greatest extent, and the scientific research cost of generation-adding breeding is saved.

Description

technical field [0001] The invention relates to an additive breeding method for agricultural planting, in particular to an additive breeding method suitable for wheat in northern winter wheat regions. Background technique [0002] In agricultural planting, supplementary reproduction is a reproduction process that uses certain technical means under the condition of artificial intervention to exceed the reproduction cycle and reproduction number of the species itself. Wheat in the winter wheat region of northern my country has a growth cycle of about 250 days and can only be harvested once a year. It takes a long time to select and breed wheat varieties in this area, and the efficiency is very low. However, the normal growth and development time of wheat is less than 150 days, so additional wheat breeding can be carried out in this area to shorten the breeding period. At present, the additive breeding methods used by breeders include the off-site additive breeding method and ...
