油莱黑胫病是澳大利亚油菜籽生产中的一个严重问题。越夏的黑胫病菌,秋初散放病孢子,从而使幼苗感染致病,后期茎杆基部折断,严重影响产量。澳大利亚种植的油菜品种,均系由加拿大引入,这些品种多为感病品种。1975年以前,澳大利亚新南威尔士瓦加地区的油菜籽试验地,所有的由加拿大引进的品种,均感病死亡,只有欧洲的芸苔型油菜品种存活下来。但是,欧洲的芸苔型油莱是冬性品种,生长期长达9个月。为此,科研人员将欧洲油菜作为育种材料,培育生长期只有7个月甚至更短的抗病品
Leggi blackleg is a serious problem in the production of rapeseed in Australia. More summer of black-thrip bacilli, early autumn scattered sick spores, so that seedlings infected with disease, the late stem base broken, seriously affecting the yield. Australia rape cultivars are grown, all imported from Canada, these varieties are mostly susceptible varieties. Prior to 1975, all rapeseed cultivars introduced in Canada in the Vaga region of New South Wales, Australia were susceptible to death and only the rapeseed varieties of Europe survived. However, the European Brassica oleracea is a winter-type cultivar that grows up to 9 months. To this end, researchers will use rape as a breeding material, cultivate the growth period of only 7 months or even shorter anti-disease products
