Breeding for aflatoxin resistance in groundnut: A review

Abstract

Aflatoxin contamination is the most important disease of groundnut affecting human health and international trading. Easiest method to control the aflatoxin is to develop resistant cultivar. Development of improved varieties resistance to AFs is difficult due to unavailability of high level of resistance lines, unavailability of proper screening technique, the genetics of resistance against AFs not properly understood, no correlation between various resistance types, high G x E interaction etc. Indirect selection through various trait like drought tolerance, phenol content etc. can use for selection of AFs resistance cultivar because they have correlate with it. Non-conventional methods (like transgenic method, molecular markers, protein markers for screening etc.) can help to understand resistance mechanism and development of resistant cultivar.
