Problems solved by technology

[0002] Saline-alkali land, especially inland saline-alkali land, is mostly mixed with salinization and alkalization, and the degree is very complicated, so that researchers still have to confuse saline-alkali, which is generally called saline-alkali land. Most of the laboratories use a single salt, alkali or several A simple mixture of salt and alkali, unable to obtain the real composition of Daejeon saline and alkali
[0003] Many laboratories in the world have obtained salt-tolerant barley varieties under laboratory conditions, but lost their salt tolerance when cultivated in saline-alkali soil

Embodiment 1

[0029] The method steps of efficient screening of saline-alkali-tolerant barley germplasm of the present invention are as follows:

[0030] 1. For 1710 germplasm resources from different sources, laboratory screening was carried out according to the method of the above step 1, and as a result, 617 laboratory-level 1 highly salt-tolerant materials were obtained.

[0031] 2. Select 80 representative materials from the laboratory grade 1 high salt-tolerant materials obtained above and carry out field screening in two representative saline-alkali lands according to the method in the above step 2. The screening results are not completely consistent, and they are screened by statistical analysis. Saline-alkali-resistant materials were found in both places. As a result, high-saline-alkali-tolerant materials such as Zhongchuan barley and Mei 97-1338 were screened out.

[0032] Through continuous planting in the two places, the selected high saline-alkali-resistant materials have shown...

Abstract

The invention provides a method for efficiently screening saline-alkaline tolerant barley germplasm, which comprises the following steps of: firstly, performing saline-alkaline tolerant screening on barley germplasm resources in a seed germination period through a laboratory, greatly eliminating a batch of germplasm, and relieving field selection pressure; then selecting local representative saline-alkali soil, meanwhile, screening barley germplasm resources with high saline-alkali tolerance in the germination period in the field, and barley resources suitable for being planted in the local saline-alkali soil can be screened out. By means of the method, a batch of barley germplasm resources with high saline-alkaline tolerance suitable for local planting are selected and screened out withintwo years, and precious parent resources are provided for barley saline-alkaline tolerance breeding.

Description

technical field [0001] The invention relates to a method for efficiently screening saline-alkali-tolerant barley germplasm. Background technique [0002] Saline-alkali land, especially inland saline-alkali land, is mostly mixed with salinization and alkalization, and the degree is very complicated, so that researchers still have to confuse saline-alkali, which is generally called saline-alkali land. Most of the laboratories use a single salt, alkali or several The simple mixture of salt and alkali cannot obtain the real composition of Daejeon saline and alkali. [0003] Many laboratories in the world have obtained salt-tolerant barley varieties under laboratory conditions, but lost their salt tolerance when cultivated in saline-alkaline soil. Contents of the invention [0004] In order to solve the existing methods in the prior art, the present invention provides a method for efficiently screening saline-alkali-tolerant barley germplasm. The invention can easily select t...
