摘要
大豆孢囊线虫病在我市危害严重,一般减产30％一50%,重者绝产。自1984～1992年进行了抗大豆孢囊线虫病的品种间杂交育种选育和示范工作,并选育出 84-51新品系。该品系生育期 96—98天,植株直立,株高1m以上,抗病、耐涝、耐旱、高产。1992年在胶州、莱西、即墨试验示范3000亩,增产幅度为61.1％～100％。
The soybean cyst nematode (SCN) is very serious in Qingdao, It makes 30%～50% reduction in yeild, even more seriously no yeild .The cross breeding for SCN was carried out from 1984 to 1992, A mew strain 84-51 was selected. lt's growth period is 96～98 days, stem upright, about 1 m high, SCN-resistant, waterlogging-resistant, dronght-resistant, high yeild.
