利用灰色关联分析方法 ,得出优质饼干麦“德麦四号”的主要生物性状对产量的影响为 :千粒重 >基本苗 >株高 >穗粒数 >公顷穗数。经稳定性参数分析具有高产稳产、适应性广、抗“空壳”的特点 ,经品质分析各项指标已达到优质饼干小麦的标准 ,该品种已成为我州主栽品种。根据分析结果 ,提出相应的栽培措施 ,为今后更大范围的开发利用提供科学依据 Gray relational analysis method was used to conclude that the main biological traits of high-quality biscuit wheat “Demai IV” were as follows: 1000-grain weight> basic seedling> plant height> number of grains per ear> number of spikes per hectare. The analysis of stability parameters with high and stable yield, wide adaptability, anti-“empty shell” features, the quality of the indicators have reached the high quality biscuit wheat standards, the variety has become the main varieties in our state. According to the analysis results, put forward the corresponding cultivation measures for the future development of a wider range of scientific basis
