Method for breeding distinguished germ plasm of high-grade triticale rich in chrome

Abstract

A method for culturing the specific germplasm of high-quality Cr-enriched black wheat 'Jizi 439' includes such steps as hybridizing between Australian black wheat 14928 as female parent and 95-5031 as male parent, hybridizing between the hybrid F1 as female parent and tetraploid hard-grain wheat 190268 as male parent, rescue of F0 embryo, indoor passage, choosing new line Ai-8 from F3 generation, hybridizing between said Ai-8 and Luozhen 1, anther culture of the hybrid F1 generation, treating the calli by slow radiation, and transplanting the regenerated plants in field.

[0001] The invention relates to a method for cultivating a chromium-rich, high-quality triticale specific germplasm, which belongs to the field of agricultural research. Background technique

[0002] With the improvement of people's living standards, a significant decrease in labor intensity and changes in eating habits, the incidence of diabetes has risen rapidly and is showing a younger trend, posing a serious threat to life and health. Before 1980, the incidence of diabetes in my country was only 0.3% of the total population.
