The access to hybrid maize is very limited for Nepalese farmers. In order to identify high yielding maize hybrids, eighteen maize hybrids were tested under coordinated varietal trial using randomized complete block design in two replicates in 2007/08 to 2008 /09 during winter seasons at National Maize Research Program, Rampur, Chitwan, Nepal. The results showed that, among studied traits, hybrids exhibited significant differences for tasseling, silking and grain yield in both years. The hybrid namely L3/L2 produced the highest grain yield (7.2 t/ha) followed by L1/L3 (6.4 t/ha) and P UTU-20/AG-27 (5.9 t/ha), respectively. The results indicated that these hybrids were promising; they should be tested under on-farms and promoted for general cultivation in Terai region of Nepal. http://pubs.sciepub.com/wjar/2/1/4/wjar-2-1-4.pdf maize hybrid grain yield and winter season
