Breeding method for high-resistant white glutinous millet variety

Abstract

The invention discloses a breeding method for high-resistant white glutinous millet variety and belongs to the technical field of resistance breeding for special millets. In the method, a white glutinous millet variety, a drought-resistant variety, a millet blast resistant variety, a downy mildew resistant variety, a kernel smut resistant variety, an herbicide resistant variety and a rust disease resistant variety are employed as parents; hybridization and multiple cross pyramid are carried out, and then through multiple generation of identification on resistance and screening on seed coat color, selenium content and agricultural and yield characters, the white glutinous millet variety having the grain character of white and glutinous grains and being drought-resistant, herbicide-resistant and diseases-resistant can be bred. The variety has good quality, high nutritional value, good resistances and high yield, reduces usage amount of pesticides, reduces labor intensity, increases yield and reduces environment pollution, thereby increasing incoming of farmers.

Description

technical field [0001] The invention specifically relates to a method for breeding high-resistant white glutinous millet varieties, and belongs to the technical field of special millet resistance breeding. Background technique [0002] Millet is a traditional crop in northern my country and one of the important food crops, occupying an important position in agricultural and animal husbandry production. my country's millet planting area and output both rank first in the world, and the planting area accounts for 80% of the world's millet planting area. Millet is a traditional drought-resistant crop. It has outstanding characteristics such as drought resistance and barrenness, high water use efficiency, wide adaptability, rich and balanced nutrition, and high forage protein content. As the drought becomes more and more severe, people's dietary structure needs to be adjusted urgently, and animal husbandry continues to develop. Under the circumstances, millet will play an import...

Problems solved by technology

Millet rust is also a major disease in millet production. Rust fungi are obligate parasites. With the large-scale promotion and application of single disease-resistant varieties, it can lead to the emergence of physiological races with stronger pathogenicity, causing the varieties to lose disease resistance. It causes huge economic losses in production, and also makes scientific research and breeding work in a passive state. The key to long-term and effective control of this type of disease is to continuously explore and utilize new resistant source materials and breed new rust-resistant varieties.
