马铃薯的退化,主要是由于马铃薯感染了某些病毒,从而导致产量逐年下降,严重地影响着马铃薯生产。据科学试验和生产实践证明:利用无毒或少毒的种薯做种,能显著地提高产量。我们于1973～1977年在马铃薯株系选、留种工作中,采用指示植物鉴定、马铃薯X病毒抗血清鉴定,选出的马铃薯优良株系比劣株系增产一倍半到两倍。利用抗血清鉴定是一种选优汰毒的有效手段。在马铃薯无病原种生产过程中,对各
The degradation of potatoes is mainly due to the fact that some viruses are infected by the potato, which leads to a year-by-year decline in output, which seriously affects the potato production. According to scientific experiments and production practices have proved that: the use of non-toxic or less toxic seed species, can significantly improve the yield. In 1973-1977, we selected indica plant identification and potato virus X virus antisera to identify and select the best potato lines to double or double the yield of inferior potato lines. The use of antisera identification is an effective means of optimizing the elimination of poison. In the potato-free pathogen production process, each
