摘要
以长江中下游冬播麦区扬麦系列(扬麦13、扬麦16、扬麦18、扬麦20、扬麦21)为材料,在忻定盆地春播条件下于2018、2019两年进行大田试验,利用平均产量、比对照增(减)百分比、变异系数、高稳系数及回归系数对南引品种扬麦系列进行丰产性、稳产性及适应性分析;对品种产量及产量构成因素进行统计分析,比较扬麦系列在引种前后的变化趋势。结果表明:冬麦春播条件下扬麦系列品种的丰产性,稳产性及适应性具有较大差异。其中,扬麦21和扬麦20表现较为突出,两品种每年的平均产量都在400 kg/亩左右,显著高于其他品种,其产量构成因素较为协调;而扬麦16表现最差,其平均产量亦连续两年位列南引品种扬麦系列之末。扬麦20和扬麦21是两个丰产性,稳产性及适应性都表现较好的南引品种,在忻定盆地春麦生产区有良好的推广前景。
With five good winter wheat cultivars(Yangmai 13,Yangmai 16,Yangmai 18,Yangmai 20,Yangmai 21)selected from the middle and lower reaches of the Yangtze River as test materials,under the condition of spring sowing in Xinding basin,field experiments were carried out in 2018 and 2019.Using average yield,percentage increase(decrease),variation coefficient,high stability coefficient and regression coefficient to analyze the high yield,stable yield and adaptability of Nanyin Yangmai series;Using difference significance to analyze the relationship between yield and yield components,and simply analyze the change rule of Nanyin Yangmai series before and after introduction.The results showed that under the condition of winter wheat spring sowing,the performances of high yield,stable yield and adaptability of different varieties in Yangmai series were quite different.Among them,Yangmai 21 and Yangmai 20 showed outstanding performance,which is related to the more prominent or coordinated yield components;Yangmai 16 showed the worst performance,with its output ranking last for two consecutive years.Therefore,Yangmai 20 and Yangmai 21 are two wheat varieties with high yield,stable yield and good adaptability,which are suitable for spreading in Xinding basin and have a good application prospect.
