Embodiment 1

[0021] A breeding method for high-yield disease-resistant mung beans, comprising the steps of:

[0022] (1) Using T62-2 as the female parent and Bailu 522 as the male parent, F was obtained by artificial crossing 1 generation;

[0023] (2) put F 1 Generation and T62-2 backcross, get BC 1 f 1 generation;

[0024] (3) will BC 1 f 1 The mung bean line was obtained by selfing in the first generation, and then selecting the offspring with uniform traits for continuous selfing for 2 generations.

Embodiment 2

[0026] A breeding method for high-yield disease-resistant mung beans, comprising the steps of:

[0027] (1) Using T62-2 as the female parent and Bailu 522 as the male parent, F was obtained by artificial crossing 1 generation;

[0028] (2) put F 1 Generation and T62-2 backcross, get BC 1 f 1 generation;

[0029] (3) will BC 1 f 1 The mung bean line was obtained by selfing for 5 generations, and then selecting offspring with uniform traits for continuous selfing for 5 generations.

Abstract

The invention particularly relates to a breeding method for a high-yield resistant type mung bean. The method comprises the steps of (1) adopting T62-2 as a female parent and white-green 522 as a male parent, and subjecting the female parent and the male parent to artificial hybridization to obtain an F1 generation; (2) subjecting the F1 generation and T62-2 to back-crossing to obtain a BC1F1 generation; (3) subjecting the BC1F1 generation to selfing, selecting a later generation neat and uniform in phenotypic expression, and subjecting the selected later generation to successive inbreeding and breeding to obtain a mung bean strain. The mung bean strain bred through the above method is high in yield, strong in disease resistance, and excellent in comprehensive properties.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding high-yield and disease-resistant mung beans. Background technique [0002] Jilin Province has a long history of mung bean cultivation, and it is grown all over the province. 80% of them are located in Baicheng and Songyuan in the west. The average annual planting area of ​​mung beans in the province is more than 1.5 million mu, and the annual output exceeds 200,000 tons. Due to the low investment in mung bean production and extensive field management, farmers have grown mung beans mainly from local varieties for a long time, and the yield per unit area is only about 1000 kg / ha. [0003] At present, in the production of mung bean, the varieties are mixed, the yield is low, and the phenomenon of being easily infected by diseases and insect pests is serious. It is urgent to replace the high-quality varieties. Contents of the invention [0004] Aiming at the d...
