13. Evaluation of advance bread Wheat lines in preliminary Wheat yield trial
Main Article Content
Abstract
Development of superior crop varieties is the prime objectives of all plant breeding programs. Fourteen bread wheat lines selected from 20th Semi Arid Wheat Yield Trials received from CIMMYT-Mexico. The experiment was planted in randomized complete block design with three replications at Barani Agricultural Research Station, Kohat during 2013-14. Data were recorded on days to heading, days to maturity, plant height, tillers m-2 and grain yield. Analysis of variance revealed highly significant differences among genotypes for all the traits studied. Seven entries viz. E-304 (4033 kg ha-1), E-311 (4844 kg ha-1), E-314 (4222 kg ha-1), E-325 (3889 kg ha-1), E-360 (4456 kg ha-1), E-384 (4533 kg ha-1) and E-388 (4300 kg ha-1) out yielded check cultivar KT-2010 (1455 kg ha-1) and will forwarded for multi-location testing to be released as new variety for rainfed areas.
