Abstract
Multilocation testing of the Coordinated Varietal Trial (CVT) of wheat genotypes were conducted at different hill research stations of Nepal Agricultural Research Council (NARC) during the normal planting season of 2012/13 and 2013/14. Twenty genotypes including two check varieties were included in Randomized Complete Block (RCB) design with three replications in the experiment. Data on the different yield attributing traits were recorded. Highly significant difference (p<0.01) among the genotypes for the days to heading, days to maturity, plant height, thousand grain weight and grain yield was observed in 2012/13. Wheat genotype BL 4061 had the highest grain yield with 3802 kg/ha followed by NL 1153 (3736 kg/ha), NL 1159 (3733 kg/ha), NL 1154 (3674 kg/ha) and NL 1156 (3462 kg/ha). In 2013/14 also a highly significant difference among the tested genotypes for all the recorded traits was observed and these genotypes were stable for the yield and yield attributing traits. The most promising genotypes for the grain yield was NL 1153 (5816 kg/ha) followed by NL 1178 (5760 kg/ha), NL 1156 (5454 kg/ha), NL 1159 (5259 kg/ha) and NL 1179 (5075 kg/ha). From the yield and other yield attributing trait wheat genotypes NL 1055, NL 1153, NL 1159, NL 1156 and NL 1179 need to be tested under farmers’ field for further confirmation and release as variety.
