Method of improving Huaxi gray radish new variety breeding

Abstract

The invention discloses a method of improving Huaxi gray radish new variety breeding. The method uses Huaxi gray radish seeds as breeding materials and builds a gray radish breeding material garden to conduct observation for every plant and at regular interval, the phenological period, the yield, the properties and the disease resistance are observed, and the field management and survey are conducted; the fleshy roots of the Huaxi gray radish have two types of milk white and faint yellow during breeding, the field disease plants and the mixed plants are cleared to conduct the group harvest and autumn sowing, the mixed plants are cleared again, the plants with same properties are preserved and harvested in a mixed mode, the plants with the fleshy roots being milk white are screened, the screened plants are planted in a separated mode, the plants are harvested and sowed after purification and rejuvenation, and good plants selected from the plants obtained from the autumn sowing are harvested independently, threshed in a mixed mode and used as protospecies seeds of a new variety obtained from breeding.

Description

technical field [0001] The invention relates to the technical field of vegetable breeding, in particular to a method for improving the breeding of new varieties of Huaxi gray radish.
