Description

METHOD OF EVALUATING QUALITY TRAIT STABILITY OF WHEAT
TECHNICAL FIELD
The present disclosure relates to the technical field of ag- ricultural breeding, in particular to a method of evaluating qual- ity trait stability of wheat.
BACKGROUND ART
The quality of wheat is affected by both genotype and envi- ronment. In different growing environments, quality traits of wheat are different, and the materials of different genotypes are also affected by the environment to a different degree. Therefore, the risk of wheat production can be reduced by finding and using varieties less affected by environmental factors and with stable genotype regulation and expression. At the same time, the selec- tion and utilization of varieties with stable expression of quali- ty traits is also crucial for processing enterprises, and is a matter of great concern to processing enterprises.
In recent years, more and more attention has been paid to the quality stability of wheat. The stability analysis method used is basically multi-year multi-point testing and quality testing. Alt- hough the effect is reliable, it is time-consuming and labor- intensive, and the progress of quality breeding and improvement is greatly limited. In view of this, it is of great significance to provide a rapid, reliable and comprehensive method for evaluating the quality stability of wheat.
SUMMARY
In view of the above deficiencies, the purpose of the present disclosure is to provide a method of evaluating quality trait sta- bility of wheat, and the method has the characteristics of rapidi- ty, high accuracy and comprehensiveness.
In order to achieve the above object, the present disclosure adopts the following technical solutions:
A method of evaluating quality trait stability of wheat pro-
vided in the present disclosure includes following steps:
Sl, preparing to-be-tested wheat samples and reference varie- ties before a normal sowing season of the wheat; 32, setting up the to-be-tested wheat samples and the refer- ence varieties in 31 into experiment groups according to cross- influence of sowing date factor, sowing density factor and fertil- ity level factor, and keeping field management for each of the ex- periment groups consistent; and 33, non-destructively detecting crude protein content, starch, wet gluten, sedimentation value and grain hardness by a near-infrared whole grain quality analyzer after the samples in S2 are harvested, performing data processing and analysis, and evalu- ating quality trait stability of the to-be-tested wheat samples.
Further, the reference varieties in step S81 include recog- nized (or more influential) high-gluten certified varieties, medi- um-gluten certified varieties or weak-gluten certified varieties under local ecological conditions.
The purpose of setting reference varieties in the present disclosure is to set a scale. Quality traits are easily affected by environmental changes, and index values fluctuate greatly, therefore, the influence of uncertain factors can be effectively controlled and the objectivity and effectiveness of evaluation are ensured by selecting recognized varieties.
Further, in step S2, a test site is required to have uniform soil, fertilizer and water conditions, drill or broadcast, and fixed seedlings, the plot area is 1.5 to 3 square meters, which ensures that more than 0.5kg of seeds can be harvested, and exper- iments are designed according to random groups, and can also be adjusted according to needs and specific circumstances.
Further, at least two factors of the sowing date factor, the sowing density factor and the fertility level factor are included when setting up the experiment groups according to cross-influence in S2.
Further, the sowing date factor includes early sowing (20 to 60 days before normal sowing), normal sowing and late sowing (20 to 60 days after normal sowing), which can also be adjusted ac- cording to an actual local reproductive period.
Further, the sowing density factor includes high sowing den- sity (1.5 to 3.5 times of normal sowing density), normal sowing density and low sowing density (0.3 to 0.8 times of the normal sowing density), can also be adjusted according to the actual lo- cal sowing conditions, which can also be adjusted according to the actual local sowing situation.
Further, the fertility level factor includes high fertility level (1.5 to 2.5 times of normal fertility level), normal fertil- ity level and low fertility level (0.3 to 0.8 times of normal fer- tility level), which can also be adjusted according to local actu- al conditions.
Further, the data processing and analysis in S3 includes a mean value of amplitude variation and mean trend for both the to- be-tested wheat samples and the reference varieties under influ- ence of different factors.
Further, the evaluating quality trait stability of the to-be- tested wheat samples in S3 includes quality stability evaluation of a single experiment group and comprehensive quality stability evaluation.
Further, in the quality stability evaluation of a single ex- periment group, the quality trait stability of the to-be-tested wheat samples is measured by comparing differences of a same index between the to-be-tested wheat samples and the reference varieties under different treatment factors and levels, specifically includ- ing: regarding the stability as good when under influence of dif- ferent factors, the mean trend of the to-be-tested wheat samples and the reference varieties is consistent and a difference in a mean value of amplitude variation of the to-be-tested wheat sam- ples and the reference varieties is consistent; regarding the sta- bility as general when under the influence of different factors, the mean trend of the to-be-tested wheat samples and the reference varieties is consistent, but the difference in a mean value of am- plitude variation of the to-be-tested wheat samples and the refer- ence varieties is large (the mean value of amplitude variation ex- ceeds 1045); and regarding the stability as poor when under the influence of different factors, the mean trend of the to-be-tested wheat samples and the reference varieties is not consistent, and the difference in a mean value of amplitude variation of the to- be-tested wheat samples and the reference varieties is large (the mean value of amplitude variation exceeds 1045).
Further, the comprehensive quality stability evaluation is specifically: considering the comprehensive quality stability of to-be-tested wheat varieties to be good when the quality stability evaluation of all single experiment groups of the to-be-tested wheat varieties is good stability; considering the comprehensive quality stability of the to-be-tested wheat varieties to be good when the quality stability evaluation of all single experiment groups of the to-be-tested wheat varieties comprises good stabil- ity and general stability and does not comprise poor stability; considering the comprehensive quality stability of the to-be- tested wheat varieties to be general when the quality stability evaluation of all single experiment groups of the to-be-tested wheat varieties is general stability; and considering the compre- hensive quality stability of the to-be-tested wheat varieties to be poor when the quality stability evaluation of all single exper- iment groups of the to-be-tested wheat varieties comprises poor stability.
In conclusion, the present disclosure has the following ad- vantages: 1. In the method of evaluating quality trait stability of wheat provided in the present disclosure, the effects on crude protein content, starch, wet gluten, sedimentation value and grain hardness are investigated from the factors of sowing date, sowing density and fertility level, and the quality stability evaluation of a single experiment group and the comprehensive quality stabil- ity evaluation of the to-be-tested wheat samples are carried out, which is more conducive to the accuracy and stability of the eval- uation system. 2. The evaluation method of the present disclosure is simple and convenient to operate, fast in speed, intuitive in results and strong in practicability, thereby the selection of wheat varieties can be effectively guided.
