Breeding method for drought-resistant high-quality millet

Abstract

The invention discloses a breeding method for drought-resistant high-quality millet. The method adopts a continuous directed breeding method combining parallel floods and droughts with a pedigree method to define character screening criteria for each breeding generation so as to breed a variety of drought-resistant high-quality millet. The technical scheme disclosed in the invention is as follows:the continuous seven-generation directed breeding of millet hybrids by using the method disclosed in the invention is performed, and based on the high yield, drought resistance and variation range and heritability of other characters of the millet, the combination of specific breeding methods and breeding characters is conducted on the different generations, so that new millet varieties with thehigh drought resistance and high nutrition quality are bred on the basis of excellent comprehensive characters.

Description

technical field [0001] The invention relates to the technical field of millet variety breeding, in particular to a drought-resistant and high-quality millet breeding method. Background technique [0002] The Xiagu region of North China is an important distribution center for millet production. Drought is one of the bottlenecks affecting local agriculture, and the drought tends to worsen year by year. In addition, the lack of distinctive varieties seriously restricts the current agricultural development. The key to getting rid of poverty and becoming rich is to develop characteristic agriculture that meets market demand based on the local area. [0003] Millet has strong drought resistance and is an advantageous and characteristic crop in our province. In recent years, with the improvement of breeding level and the intensification of popularization, high-yield varieties, high-quality varieties, and drought-resistant varieties are being recognized by people. The yield of mill...

Problems solved by technology

In recent years, with the improvement of breeding level and the intensification of popularization, high-yield varieties, high-quality varieties, and drought-resistant varieties are being recognized by people. The yield of millet in Hebei Province has increased significantly. The yield potential of millet varieties is far from being brought into play, the average per unit yield of millet in the province is still not high, and the yield potential is still great

[0004] Most of the studies on drought resistance of millet focus on the research on drought resistance at the germination stage and seedling stage, and are evaluated by the survival rate or the degree of inhibition, which is suitable for basic research on a large number of materials and does not involve yield issues. In actual production, Yield is still very important. The drought resistance identification of the whole growth period has a long cycle, high requirements for facilities, and great work intensity. There are few experiments in this area, but drought often affects all growth stages of millet. Therefore, only by breeding varieties with strong drought resistance throughout the growth period can they meet the actual needs of production and be easily accepted by farmers
