1980年初,北京作物学会在平谷县召开了1979年小麦年会。会上除交流总结了一年来小麦各项试验研究成果和丰产经验外,还围绕当前郊区小麦品种工作中的问题进行了热烈的讨论。大家认为,解放以后,特别是从1957年以来,北京郊区不断推广和更换小麦良种,对全市小麦增产起了很大促进作用。1966年以后,育种工作由于受到林彪、“四人帮”的干扰破 In early 1980, the Beijing Crops Society convened the 1979 Wheat Annual Meeting in Pinggu County. In addition to exchanging and summarizing the results of wheat experiments and high yielding experiences in the past year, the conference also held heated discussions on the issues concerning the current work on wheat varieties in the suburbs. We believe that since the liberation, especially since 1957, the popularization and replacement of wheat seeds in the suburbs of Beijing has played a significant role in boosting the output of wheat in the city. After 1966, the breeding work was broken by the intervention of Lin Biao and the “gang of four.”
