台湾每年进口玉米三百万吨以上,省产玉米最高生产量是1986年达27万余吨。不论进口或省产玉米,均易感染黄曲菌,对畜产颇有危害。而黄曲菌在玉米生长田间及贮藏期间均能感染,因此要从育种方面探索解决黄曲毒素的办法。世界上有关黄曲菌的育种始于1970年,由于黄曲菌天然感染极为分散而变异极大,因此分离抵抗基因型比较困 Taiwan imports more than 3 million tons of maize annually, and the maximum output of maize produced in Taiwan was 27 million tons in 1986. Regardless of the import or production of corn, are susceptible to yellow aspergillus, quite dangerous to livestock. However, the yellow aspergillus can infect both during the field of corn growing and during the storage period. Therefore, we should explore the solution to the toxoid from breeding. Breeding of the yellow aspergillus in the world began in 1970, because of natural infection of the yellow aspergillosis extremely variable and extremely variable, so the isolation of resistant genotypes more sleepy
