A kind of breeding method of waxy corn and white waxy corn inbred lines

Abstract

The invention discloses a method for breeding waxy corn and white waxy corn inbred lines. Wherein, the method for breeding waxy corn inbred lines includes the following steps: using one of the waxy corn varieties as the female parent and the other waxy corn varieties as the male parent to form multiple hybrid combinations. Select one of the hybrid combinations, collect the pollen of other hybrid combinations and mix them evenly in equal amounts. The selected hybrid combination is pollinated by uniformly mixed pollen, and target hybrid seeds of the pollen and the selected hybrid combination are obtained. According to the preset target traits, the target hybrid seeds are self-bred to obtain a stable waxy corn inbred line. In the above breeding process, adding the step of selecting and retaining white kernels can realize the breeding of white waxy corn inbred lines. Through hybridization and mixed pollen pollination, excellent genetic resources are gathered, so that the bred inbred lines can adapt to various ecological types, have outstanding high temperature and low temperature resistance, and have strong disease resistance and stress resistance.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for breeding waxy corn and white waxy corn inbred lines. Background technique [0002] With the improvement of people's living standards and the strengthening of health awareness, people have put forward new requirements for the types, nutritional components, appearance, color and health functions of fresh waxy corn products. Fresh and delicious waxy corn products are deeply loved by consumers due to their unique flavor, rich nutrition, health care and leisure. In addition, they are suitable for fresh-keeping processing and can be supplied year-round, and the market demand continues to expand. [0003] In addition, due to the short growth period of fresh waxy corn, relatively simple cultivation, and significant economic benefits, its cultivation area continues to expand. [0004] However, with the volatile climate in recent years, new requirements have been added...
