Breeding method for purple waxy corn inbred line

Abstract

The invention relates to a breeding method for a purple waxy corn inbred line. The breeding method comprises the following steps of: (1) hybridizing waxy corn varieties including the Beijing sweet and purple waxy corn No. 2 used as a female parent with the Jiangsu waxy corn No. 5 used as a male parent to obtain a hybrid cluster, and selfing a Beijing sweet and purple waxy corn No. 2 single plant to obtain a selfed cluster; (2) selecting and reserving a purple corn seed from the hybrid cluster, planting the selected corn seed to obtain a female parent, and hybridizing the female parent with a male parent which is obtained by planting a purple seed which is selected from the selfed cluster to obtain hybrid seeds; and (3) planting the hybrid seeds, bagging, selfing the plants, selecting and reserving purple seeds continuously, planting the selected purple seeds, selecting superior individual plants by combining the stress resistance and qualitative characters, and selfing 4-5 generations of the superior individual plants continuously to breed a stable purple waxy corn inbred line ZN-01. The breeding method can ensure that all the developed hybrid seeds have the characteristics of high quality, high stress resistance, wide application range and good commodity performance.

Description

technical field

[0001] The invention relates to a method for breeding purple waxy corn inbred lines, and belongs to the technical field of breeding new varieties of crops. Background technique

[0002] Since fresh waxy corn is a new type of food rich in nutrition, healthy and safe, and it is easy to cultivate and has obvious benefits, the cultivation area is expanding year by year. However, with the improvement of people's living standards, new requirements have been put forward for the color and quality of waxy corn. Requirements, there are relatively few high-quality varieties that meet consumer demand on the market. Breeding of high-quality waxy maize inbred lines is the prerequisite for new varieties. Therefore, it is particularly important to breed purple waxy maize inbred lines with high quality, good resistance and good commerciality. It can be compared with white waxy and purple waxy maize. The inbred lines have produced new varieties of Huanuo and Ziwao corn to mee...

Embodiment Construction

[0016] The seeds of Jingtian Zihuanuo No. 2 and Suyunuo No. 5 used in the present invention are commercially available.

[0017] The specific steps of applying the method of the present invention to select and breed the purple waxy corn inbred line ZN-01:

[0018] The first step: cross the waxy corn variety Jingtian Zihuanuo 2 as the female parent and Suyunuo 5 as the male parent to obtain hybrid ears, and self-cross the single plant of Jingtian Zihuanuo 2 to obtain selfed ears;

[0019] The second step: select the purple seed in the hybrid ear to be the female parent after planting, and hybridize with the purple seed in the selfed ear to be the male parent after planting to obtain hybrid seeds;

[0020] The third step: plant the hybrid seeds obtained in the second step and bag them for self-crossing, continue to select purple seeds for planting, and combine stress resistance and quality traits to select excellent single plants for continuous self-crossing for 4 to 5 generatio...
