Problems solved by technology

In addition, the drought resistance performance of millet in different growth periods is often different. Only the research on drought resistance in each growth period, that is, the whole growth period, can meet the actual production needs. large, which limits its research and development, and drought often affects all growth stages of millet. Only by breeding varieties with strong drought resistance throughout the growth period can they be easily accepted by farmers

Embodiment 1

[0029] This example relates to a method for breeding drought-resistant high-quality millet.

[0030] Among the rich and diverse variety resources and the breeding intermediate materials selected by each unit and the popularized varieties, the traits that meet the requirements of the breeding objectives are distributed to varying degrees, but the comprehensive traits of most farm varieties (the comprehensive traits include: yield traits, agronomic traits, Economic traits, quality traits, and stress resistance) are poor, and it is difficult to achieve high-yield breeding goals. The materials in the spring valley area often cannot adapt to the local climate, exhibit premature aging and low yield, and are difficult to use. Most of the intermediate breeding materials and popularized varieties have relatively low comprehensive traits. it is good. Therefore, it is determined to select parental materials mainly from intermediate materials and popularized varieties, taking into account...

Embodiment 2

[0071] This example relates to the identification of the main traits of the selected varieties obtained in Example 1.

[0072] In order to ensure the excellence of the varieties, authoritative organizations are entrusted to conduct appraisals on drought resistance, disease resistance, and nutritional quality, and to carry out examination (appraisal) or registration in accordance with the state's management methods for varieties.

[0073] (1) Regional test output identification, the identification results are shown in the following table (Table 7):

[0074] Table 7. Summary results of national millet regional experiment yield

[0075]

[0076] It can be seen from the above table that the two-year average yield per mu of the selected variety of the present invention is 320.9kg, which is 6.33% higher than that of the control "Jigu 19", ranking second among all the tested varieties.

[0077] Through the identification of the National Millet Variety Appraisal Committee, the sel...

Abstract

The invention discloses a breeding method of drought-resistant high quality millets. The breeding method adopts a flood and drought parallel and pedigree technology combined continuous directional breeding technology to clarify the property screening criteria of every breeding generation in order to obtain the drought-resistant high quality millets. The breeding method is adopted to directionally breed seven consecutive generations of a millet hybrid progeny and carry out specific breeding and property breeding combination on different progenies according to the variation range of the high yield, the drought resistance and other properties and other heritability characteristics of the millets in order to cultivate a new millet specie with high drought resistance, nourishing and high quality in the whole growth period based on excellent comprehensive properties.

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 is getting worse year by year, which seriously restricts the current agricultural development. Millet has strong drought resistance. With the improvement of breeding level and the increase of promotion, high-yield varieties, high-quality varieties, and drought-resistant varieties are being recognized by people. However, due to adverse factors such as drought and disease, the yield potential of millet varieties is far from If it can be brought into full play, the average per unit yield of millet is still not high, and the yield potential is still great. [0003] Years of research have shown that the drought ...
