小麦品种抗绣稳定性常受绣菌生理小种变异和区系消长的影响。每年結合銹菌圃观察和从全国各地采集一定数量的夏孢子世代标样,在一定条件下,在鑑別寄主上加以測定和分析,从而了解绣菌小种发生变化的情况。 1962年全国小麦秆绣病輕度流行,田间一般发病甚輕。当年共采得十五个省的秆锈菌标样620个,經保存后繁殖存活而参加鑑定的标样有 The stability of wheat varieties resistant to embroidering is often affected by the variation of race and its growth and decline. Combined with the observation of rusty nursery garden and the collection of a certain number of standard samples of summer spore generation from all over the country, it is determined and analyzed on the identification host under certain conditions so as to understand the changes of the small species of the embroidered plants. 1962 wheat stalw embroidery mild prevalence in the field is generally mild. In the same year, a total of 620 stalk samples of stalk rust were collected from the 15 provinces, and the samples that survived after being preserved for identification were
