Farmers' field trials were conducted for three consecutive years during 2014-16 rainy seasons at two locations, one in each Dhanusha and Mahottari districts of Nepal to identify farmers preferred high yielding rice genotypes for irrigated ecosystem. A total of ten rice genotypes were evaluated in a randomized complete block design with three replications.  The tested genotypes were significantly different (P=0.01) for growth duration and grain yield. The genotypes IR87615-9-3-1, IR78875-207-B and HUA 565 produced significantly higher grain yields across the locations and produced grain yield of more than 4 t ha-1. The high yielding and farmers preferred genotypes were IR87615-9-3-1, HUA565 and Ciherang Sub1. The findings of the study show that these promising genotypes need to be disseminated to other locations of similar agro-climatic conditions to offer varietal options to the farmers.
