甜椒是重要的夏、秋蔬菜之一,在周年供应中也占有重要地位。近年来,北京地区由于病毒病严重,产量逐年降低。据市菜蔬公司统计,1977年的甜椒平均亩产比1970年降低63%,直接影响了甜椒生产和市场供应。1976年和1978年,我们在北京郊区开展了甜椒病毒病发生情况的调查和毒原鉴定工作,这对于进一步开展甜椒品种抗病性鉴定和抗病育种工作有着重要意义。现将初步结果整理如下: Pepper is one of the important summer and autumn vegetables, also occupy an important position in the annual supply. In recent years, due to the serious virus disease in Beijing, the output has been decreasing year by year. According to the statistics of the vegetable company, the average yield of bell peppers in 1977 was 63% lower than that in 1970, which directly affected the production and market supply of bell peppers. In 1976 and 1978, we investigated the occurrence of bell pepper virus disease and the identification of virulence in the suburbs of Beijing, which is of great significance for the further development of disease resistance identification and disease resistance breeding of bell pepper varieties. The preliminary results are now organized as follows:
