采用高产毒的黄曲霉孢子接种花生仁,测定接种后种子感染率和黄曲霉毒素的含量,对853份花生种质资源进行筛选鉴定。鉴定出701,702,超小粒1号和超小粒2号4个高抗黄曲霉素的花生品种(品系),其接种感染率3年平均依次为13.6%,14.1%,16.1%和13.7%,对照种桂花14号4年平均为95.2%。
Peanut kernels were inoculated with high-yielding Aspergillus flavus spores to determine the seed infection rate and aflatoxin content after inoculation, and 853 peanut germplasm resources were screened and identified. Four peanut cultivars (lines) with high resistance to aflatoxin were identified as 701,702, No. 1 and No. 2, respectively. The average inoculation rates for the three strains were 13.6%, 14.1%, 16 .1% and 13.7%, respectively. The average annual rate of osmanthus 14 was 95.2%.
