Evaluation of Some Improved Wheat (Triticum aestivum L.) Genotypes for Growth and Yield Potential

Abstract

An experiment was conducted at the Research Farm of the Department of Genetics and Plant Breeding of Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during 2015-2016 to study the performance of the selected wheat variety based on some morphological traits. Twenty four wheat varieties were used in the experiment where they were collected from Wheat Research Centre, Bangladesh Agriculture Research Institute, Dinajpur. The experiment was conducted in randomized completely blocked design with three replications. Different yield contributing traits like thousand grain weight (g), number of grains per spike, number of spikelet’s  per spike, days to anthesis, heading days, plant height (cm), days to maturity and grain yield (g/plot) were assayed. The result of the analyses of variance for all the traits showed significant differences among the genotypes. The experimental result demonstrated that the variety PYT-15, BARI Gom 25 and PYT-12 performed better among the tested genotypes in relation to yield and yield contributing traits and those could be recommended for further popularization in different wheat growing regions of Bangladesh.
