Heijingu breeding method

Abstract

The invention provides a Heijingu breeding method. Spring triticale 76 is used as a female parent to be respectively hybridized with Zhoumai No.18 wheat and Xiaoyan No.6 wheat as male parents to respectively obtain generations F1 and F2; the plants of the generation F1 are planted; the F1 is subjected to back crossing with the Zhoumai No.18; the hybridization generation F3 is subjected to anther culture to obtain a germ line F3; then, the generation F3 is planted for self crossing to obtain F4 seeds; the plants of the generation F2 are planted; the F2 is used for performing first back crossingwith the Xiaoyan No.6 wheat; the hybridization generation F5 is subjected to anther culture; after the plants are transplanted to the field, single strain selection is performed to obtain the germ line F5; the generation F5 is planted; fertile plants are selected for self crossing; purple black seeds are harvested to obtain F6 seeds; the generations F4 and F6 are hybridized; hybridization seeds of the purple black seeds are harvested. The Heijingu line cultured by the breeding method provided by the invention has excellent yield and obvious disease agricultural characteristics; the trace element content is much higher than that of triticale.

Description

technical field [0001] The invention relates to breeding technology, in particular to a breeding method of Heijingu. Background technique [0002] Triticale is the staple food in people's daily life and the main food material for the energy source of the human body. The white flour processed from ordinary black wheat mainly contains protein, crude fiber, carbohydrates, fat and other ingredients. However, in common triticale, its nutrients, especially the trace elements necessary for the human body, are low. According to research, the protein content of common black wheat is only 11.1%, the total amino acid content is only 10.2%, and the content of trace elements such as iron, calcium and potassium is only slightly higher than that of common wheat. The current triticale varieties have unsatisfactory yield traits, low disease resistance, and low content of nutrients such as amino acids and trace elements, which can no longer meet people's requirements for nutrition and food ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems that the domestic triticale yield is not high, the nutritional value is not high, and the disease resistance is not strong, the present invention alleviates the current situation that the contradiction between the supply and demand of triticale is more and more prominent, and proposes a breeding method of black gold valley. The Heijingu black wheat strain bred not only has high yield, but also has strong lodging resistance, and is rich in types and contents of trace elements and amino acids
