Post flowering stalk rot is a serious biotic compulsion to corn production in subtropical or tropical areas. It is a disease which is incited by multiple infectives, among them Fusarium verticillioides and M. phaseolina are the utmost that involved in pith decaying, wilting and drying in early age of plants in India’s subtropical regions. Almost all the maize cultivars have exhibit a crucial level of disease incidence at tessling and silking stage. A systematic breeding programme for screening on PFSR initiated in India, collaboration with Indian Institute of Maize Research (IIMR), Ludhiana and Asian Regional Maize Program of CIMMYT. In the process of these programme, genotypes screening was carried out at ‘hotspot’ location in Udaipur, Rajasthan for PFSR, inoculated through toothpick method were using artificially the promising maize genotypes, repeatedly, resistant plants were selfed to acquire resistant cultivars. After considerable regular screening, Fusarium stalk rot, 150 maize germplasm were screened in field. Eight genotypes namely AH1625, BAU-MH-18-2, GGMH-114, GK 3207, CMH-12-686, CAH 1511, ADH 1619, and FQH-148 reveal highly resistant genotypes with disease score of 1.0-2.0. previously mentioned genotypes may be convenient for resource use in breeding for resistant to PFSR disease.

Throughout the years, maize genotypes AH1625, BAU-MH-18-2, GGMH-114, GK 3207, CMH-12-686, CAH 1511, ADH 1619, and FQH-148 pick up as highly resistant response with disease score of 1.00-2.00. These genotypes show beyond doubt useful for utilization for breeding programmers to resistant response against the post flowering stalk rot disease with maximum yield in subtropical India and specially in southern Rajasthan for higher grain yield in maize
