In the breeding method, the crop characters are stable and fast, and the new variety is easily and fast bred; the bred strain has the characteristics of lodging resistance, high yield, high thousand grain weight, wide adaptability and the like.

Description

Breeding method of bare barley with double edges

Technical Field

The invention relates to the field of crop breeding, in particular to a breeding method of bare barley with double edges.

Background

Erlenmeyer barley is a subspecies of the common barley species, known under the name H.vulgare ssp. The ears are flat, the content of starch in the double-ridge-skin barley grains is high, and the quality of malting is good. However, the naked barley planted at present is mainly multi-ridge naked barley, and has low yield and poor lodging resistance.

Disclosure of Invention

The invention aims to provide a method for breeding bare barley with double edges aiming at the defects in the prior art.

In order to achieve the purpose, the technical scheme provided by the invention is as follows: a breeding method of bare barley with double edges comprises the following steps:

1) using double-arris beer barley Favawei as a female parent and Tibet double-arris naked wild barley ZYM0981 as a male parent, and carrying out artificial hybridization and matching to obtain Favawei multiplied ZYM0981 hybrid F1 'generation plants, and sowing 2 rows in F1' generation;

2) taking a high-quality stable barley strain 9810 as a female parent, taking Favaviet multiplied ZYM0981 hybrid F1' generation plants obtained in the step 1) as male parents, manually hybridizing and matching, and sowing F1 generation seeds in the next year;

3) f1 generation obtained in the step 2), sowing 2 rows, uniformly mixing and harvesting after maturation, air drying and storing to obtain F2 generation;

4) sowing 50 rows of F2 generations obtained in the step 3), sowing the seeds at 1.5m, sowing the seeds at 0.25m, sowing the seeds at 6.0cm, sowing 26 seeds in each row, sowing the seeds in 2 rows of various standard varieties before and after combination, selecting a large number of single plants in the field, harvesting the single plants, and performing air drying and storage to obtain F3 generations;

5) the F3 generation obtained in the step 4), the single plant is sown for 2 rows, the row length is 1.5m, the row spacing is 0.25m, the plant spacing is 6.0cm, 26 seeds are sown in each row, 2 rows of various standard varieties are combined, the single plant is selected and then harvested, the air drying and the storage are carried out, the F4 generation is obtained,

6) obtaining the F5 generation and the F6 generation, namely repeating the operation of the step 5), and finally obtaining the F7 generation;

7) the F7 generation obtained in step 6), a stable naked barley line was selected and designated as naked barley line 0406-17.

Further, in the above-mentioned breeding method of bare-grain barley with two edges, in the artificial hybridization process of step 1) and step 2), each plant only needs to make 1 ear and more than 5 ears when castration, and when the seeds are mature, the seeds are harvested in a mixed manner, and stored in an air-dried manner, so as to obtain hybrid seeds of F1' generation and seeds of F1 generation respectively.

Further, in the above-mentioned breeding method of barely-hulled barley, in the steps 4) to 6), selecting a single plant is selecting a single plant with a plant height of 80cm, lodging resistance, a grain number per ear of more than 20 grains, a thousand grain weight of more than 42 g and bare grains from filial generations.

The invention has the beneficial effects that: the breeding method of the bare barley with the double edges has the advantages of high speed and easy selection. In the breeding method, firstly, the scalper barley method Waviet and the scalper naked wild barley ZYM0981 are selected as parents for hybridization assembly, the character is stable and fast, and a new variety is easily and fast bred; secondly, selecting high-quality, high-yield, wide-adaptability and high-combining ability malva with skin barley as a female parent, and the bred line has the characteristics of lodging resistance, high yield, high thousand grain weight, wide adaptability and the like; and selecting the wild naked barley ZYM0981 in Tibet as a male parent, so that the bred strain can be better suitable for the naked barley (highland barley) planting area in China.

Detailed Description

Example 1:

a breeding method of bare barley with double edges comprises the following steps:

1) using double-arris beer barley Favawei as a female parent and Tibet double-arris naked wild barley ZYM0981 as a male parent, and carrying out artificial hybridization and matching to obtain Favawei multiplied ZYM0981 hybrid F1 'generation plants, and sowing 2 rows in F1' generation; in the artificial hybridization process, each plant only needs to make 1 spike and more than 5 spikes during castration, and when grains are mature, the seeds are mixed, harvested, dried and stored to obtain F1' generation hybrid seeds;

2) taking a high-quality stable barley strain 9810 as a female parent, taking Favaviet multiplied ZYM0981 hybrid F1' generation plants obtained in the step 1) as male parents, manually hybridizing and matching, and sowing F1 generation seeds in the next year; in the artificial hybridization process, each plant only needs to make 1 spike and more than 5 spikes during castration, and when grains are mature, the seeds are mixed, harvested, air-dried and stored to obtain F1 generation seeds; the barley strain 9810 is a high-generation stable strain material which is bred by self, and 94D-11 which is introduced abroad is taken as a female parent, (sweet beer No. 2 multiplied by sweet beer No. 4) is taken as a male parent for hybridization to obtain a progeny;

In the steps 4) to 6), selecting single plants is to select single plants with plant height of 80cm, lodging resistance, grain number per ear of more than 20 grains, thousand grain weight of more than 42 g and naked grains from filial generations.

The breeding process is shown in Table 1.
