摘要 为了了解长江中下游地区新育成小麦品种的生产应用价值,应用Francis-Kannenberg基因型分组法、线性回归分析法、适应性参数法和高稳系数法对参加2016—2017年度国家长江中下游冬麦组的13个小麦品种的丰产稳产性进行了研究。结果表明,较对照品种‘扬麦20’增产2%以上的小麦品种有8个,占61.5%,但丰产稳产的小麦品种较少,只有‘微红225’和‘扬辐麦2049’,仅占15.4%。FrancisKannenberg基因型分组法、线性回归分析法和适应性参数法对品种稳定性的评价结果基本一致。相关分析表明,高稳系数与平均产量呈极显著正相关,与标准差、变异系数、回归系数和适应性参数呈显著或极显著负相关。 To understand the production and utilization value of newly developed wheat varieties in the middle and lower reaches of the Yangtze River,the high and stable yield ability of thirteen wheat varieties in the regional trail of the middle and lower reaches of the Yangtze River during 2016-2017 were analyzed with the methods of Francis-Kannenberg genotype-group technique,Eberhart-Russell linear regression model,adaptability parameter and high stability coefficient.The results showed that there were eight varieties(accounting for 61.5%)with a yield increase of more than 2%compared with the control variety‘Yangmai 20’,but there were fewer varieties with high and stable yield,only‘Weihong 225’and‘Yangfumai 2049’,accounting for 15.4%.The results of Francis-Kannenberg genotype-group technique,linear regression model and adaptability parameter for the evaluation of stability of the wheat varieties were basically the same.The correlation analysis showed that high stability coefficient(HSC)had extremely and significantly positive correlation with the average yield,and significantly negative correlation or extremely and significantly negative correlation with standard deviation,coefficient of variation,regression coefficient and adaptability parameter.
