Problems solved by technology

[0003] The present invention aims at the problem that the currently promoted varieties are mainly rice-type varieties used for cooking porridge with low glutenin and dietary fiber content, and poor processing applicability in processing staple foods, and designs a kind of millet variety suitable for staple food processing. Breeding and cultivation methods, cultivating millet varieties with high glutenin and dietary fiber content suitable for staple food processing, is of great significance for improving the ductility of millet and promoting diversified breeding of millet

Embodiment Construction

[0023] The method of the present invention will be described in detail below.

[0024] The varieties popularized in Xiagu District of North China are often based on the high-quality rice type suitable for porridge, with low glutenin and crude fiber content, which is not suitable for staple food processing.

[0025] In 2009, 10 millet varieties with high gluten content, such as Yugu No. 9 and Gufeng No. 1, were screened out, and more than 100 hybrid combinations were configured. In 2012, 5 materials with higher gluten content and better agronomic properties were screened out. In 2013, a yield comparison test was carried out, and an excellent line G239 with high gluten content and good agronomic traits was screened out.

Abstract

The invention discloses a method for breeding and cultivating millet varieties suitable for staple food processing, which belongs to the technical field of crop breeding and cultivation. The steps of the breeding method include: (1) using millet materials with high glutenin content and high crude fiber The millet material of content content carries out sexual hybridization, obtains the F1 generation seed; (2) will obtain the F1 generation seed continuous selfing 3-5 generation, therefrom select the millet seed of high glutenin, high crude fiber; (3) step (2) ) The selected millet seeds are subjected to processing suitability evaluation and determination, and the millet seeds suitable for processing are selected therefrom; (4) The millet seeds selected in step (3) are multiplied to obtain the millet varieties suitable for staple food processing. The invention also provides a cultivation method for millet varieties. The invention obtains the millet variety Jigu T6 with a gluten content of 17.13g / 100g and a crude fiber content of 2.5%, which promotes the breeding of special millet varieties suitable for food processing and the development of staple food products , Drive the development of millet industrialization.

Description

technical field [0001] The invention belongs to the technical field of crop breeding and cultivation, and relates to a method for breeding and cultivating millet varieties suitable for staple food processing. Background technique [0002] Glutenin and gliadin together form gluten, which endows dough with elasticity and extensibility. It is an important factor determining the viscoelasticity of dough and plays an important role in determining the quality of wheat processing, especially glutenin plays a decisive role in the quality of wheat deep processing ( Kasarda, 1976). With the increase of gluten content, gluten, sedimentation value, and stability time all increase significantly (Zhao Naixin et al., 1998). The glutenin content in millet is 1.10-1.94g / 100g (Liu Jingke et al., 2014), and the glutenin content in wheat is 2.32-7.74g / 100g (Zhao Naixin et al., 1998). Low gluten content is one of the reasons for the lack of gluten and poor processing applicability of millet. ...
