Abstract
Maize genotypes were screened at research field of National Maize Research Program, Rampur, Chitwan on 20 maize genotypes during 2015 and 2016 summer season with the objective of identification of resistant genotypes against southern leaf blight caused by Bipolaris maydis. Field experiment was laid out in randomized complete block design with three replications. Disease scoring was done as percentage of leaf area infected using 1-5 rating scale. In both the years among the tested genotypes, disease severity and grain yield varies significantly. None of the genotypes reacted for resistant whereas four genotypes; 05SADVI, BGBYPOP, RAMS03F08 and RML-32/RML-17 were moderately resistant over the years. For grain yield most of the tested genotypes produced comparatively lower grain yield however RML-32/RML-17 was superior for grain yield (3.1 t/ha) over the years. Int. J. Appl. Sci. Biotechnol.

Highlights
Maize (Zea mays L.) is an important food and feed crop among cereal crops in the world
Site Selection The field experiment was conducted during summer season of 2015 and 2016 at National Maize Research Program (NMRP), Rampur, Chitwan, Nepal located between 84o19′ E longitude and 27o40′ latitudes and 282 m above the sea level
The highest mean grain yield was recorded from RML-32/RML-17 (3.1 t/ha) with moderate level of disease severity (2.3)
Summary
Maize (Zea mays L.) is an important food and feed crop among cereal crops in the world. Maize is the world’s widely grown cereal and primary staple food crop in many developing countries It is the principle food crop in the hills and feed for terai of Nepal. The area of this crop is increasing and establishing as a commercial commodity due to its higher yield potentiality among major crops and its ever increasing use in feed especially for poultry in terai regions of Nepal. It has a very high yield potential than any other cereals and is popularly known as 'queen of cereals' (Singh, 2002). Yield reduction up to 50% was recorded when race 'O' inoculated into susceptible line (Fisher et al, 1976; Gregory and Nelson, 1978)
