Aflatoxin contamination in groundnut under normal moisture and moisture stress field conditions

Abstract

Aflatoxin contamination of groundnut is a serious quality problem in many tropical and sub-tropical countries in the world. India is no exception to this because groundnut is cultivated in varied environmental conditions in different states of India. With an objective to find out aflatoxin contamination resistant genotype, a total of 66 groundnut genotypes were screened for aflatoxin contamination under normal moisture and moisture stress condition. Analysis of variance has revealed that there is significant variation among genotypes tested even at 1 per cent level of significance. Average aflatoxin contamination under moisture stress condition was increased by 11.53 per cent. Heritability was 98.28 per cent with a genetic advance over mean of 260.79 per cent under normal moisture and 97.33 per cent with a genetic advance over mean of 226.30 per cent. Some of the genotypes were identified with no aflatoxin contamination under both normal moisture and moisture stress conditions viz., Dh-86, Dh-101, Dh-216, Dh-246, SB-T2, SB-T13, SB-T14, VB-T31, K-9, ICGV-15119, Dh- 234 and J-11.
