[0021] Example 1 Breeding method of high-quality red amaranth new variety

[0022] (1) Introduce the original variety group in the first year - Guangdong farmhouse red amaranth;

[0023] (2) Screening of brightly colored and mutated individual plants: in the second spring, using the low-temperature ecological climate conditions in early spring in Suzhou area, adopting greenhouse-covered cultivation techniques, spring sowing of local resources of red amaranth was introduced, and three generations were selected to select single plants with beautiful colors to obtain color-stable plants. Tie;

[0024] (3) Identification of heat resistance: in the summer of the second year, using the high-temperature ecological climate conditions in Suzhou area in summer, and adopting the cultivation technology of greenhouse covering and shelter from rain, the obtained stable strains were identified for three generations of heat resistance, and stable strains of heat resistance were obtained;

Abstract

The invention belongs to the technical field of crop breeding and discloses a breeding method for a high-quality new red spinach variety. The method comprises the steps that a Guangdong red spinach farm variety is introduced, single plants are optimized in a greenhouse in spring and summer according to the appearance, the yield, the content of nitrate and the stress resistance index, wherein the color of leaves serves as an important index in the early stage; a strain garden is built, and two generations are obtained in each year; then, consecutive selection is carried out, heat resistance, a high yield, low nitrate content and the leaf color are combined, and the vegetable new red spinach variety stable in yield, high in heat resistance, rose red in color and glossy is obtained.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, and specifically relates to a method for breeding new varieties of high-quality red amaranth. Background technique [0002] Amaranth, Amaranthaceae, Amaranthus is an annual herb, Latin name: Amaranthus tricolor, with thick stems, green or red.
