Technical Regulation for Evaluating Drought and Stress Resistance of Winter Wheat Varieties at Filling Stage in Rain-fed Agricultural Areas
In order to further promote the rapid screening and popularization of drought to lerant wheat varieties and improve the efficiency of drought to lerance breeding,the evaluation rules of drought to lerant wheat at filling stage were clarified by multi-year and multi-point determination of wheat stomata characters of flag leaf under field production conditions in semi-arid rain-fed agricultural areas.By combining with the principal component analysis and membership function value method,a comprehensive evaluation method for drought tolerance of winter wheat was summarized from aspects such as the applicable range,normative references,terms and definitions,technical principles,basic requirements,field management,stomatal trait investigation and analysis,calculation of evaluation indicators,and classification of evaluation levels.
