abstract: Groundnut (Arachis hypogaea) currently ranks first among oilseed
crops in China in terms of annual production, average crop
and oil yield, and total crop value. Aflatoxin contamination has
been a crucial concern for food safety and market competitiveness
in groundnut products in most warm regions where heat
and drought stresses are generally serious. Genetic enhancement
for resistance to aflatoxin has been regarded as the most
cost-effective approach to reduce contamination risk in this
crop. Based on continuous evaluation of groundnut germplasms,
including the core collections from China, ICRISAT and USA,
several lines have been identified as resistant to Aspergillus infection
or aflatoxin production. Recently, more research efforts
have been made in identifying materials with shell resistance to
Aspergillus infection, through cooperation with ICRISAT. Efforts
have also been made in identifying and enhancing germplasm
lines with diverse resistance components or mechanisms. Several
ICRISAT breeding lines have been used in improving aflatoxin
resistance of groundnut in Chinese institutions. An elite cultivar
developed at OCRI-CAAS, Zhonghua 6, with desirable resistance
to aflatoxin production, bacterial wilt and pot rot has been
extensively used in central China. Through RNA-seq profiling, it
was found that relative higher resveratrol content in Zhonghua 6
was a key mechanism for its reduced aflatoxin production under
high infection pressure of Aspergillus sp.
