通过对两个小麦遗传群体 (“望水白”/“Alondra”和“苏麦 3号”/Alondra)在南京、苏州、建阳、武汉 4个地点连续两年 (1999～ 2 0 0 0年 )的抗赤性鉴定资料分析发现 ,抗、感性稳定品种的抗赤性以及遗传群体内个体抗、感趋势和病小穗率的频率分布均较一致。但无论是同一年份的不同地点间 ,还是同一地点的不同年份间 ,遗传群体内个体抗赤性的相关系数极小。这使小麦抗赤性分子标记的QTL分析受到影响。文章对抗赤性鉴定方法和抗赤性评价问题进行了讨论 ,提出了用于抗赤性分子标记分析的抗赤性方法的建议
Through two successive generations of two wheat genetic groups (“Alondra” and “Alondra” and “Alondra”) in Nanjing, Suzhou, Jianyang and Wuhan for two years (1999 ~ 2000) ) Analysis showed that resistance and susceptibility of stable varieties of anti-redness and genetic resistance within the individual groups, trends and the frequency of disease spike frequency are more consistent. However, the correlation coefficient of individual resistance to resistance in the genetic group is very small, no matter in different locations in the same year or in different years in the same location. This affected the QTL analysis of wheat anti-scarce molecular markers. This paper discusses the methods of evaluating the redness and the evaluation of the resistance to redistribution, and puts forward the suggestion of the anti-redness method
