Abstract

High yielding crop varieties are the need of time as the population is accelerating with an exponential rate. Genetic variability can be exploited to screen improved crop varieties to address the scarcity of food. We investigated the agro-morphology in seven bread wheat genotypes collected from International Wheat and Maize Improvement Centre Mexico (CIMMYT); Pakistan Atomic Energy Commission (NIA) Tando Jam and Wheat and Research Institute (WRI) Sakrand.  The experimental study was conducted at Wheat Research Institute (WRI), Sakrand Sindh, Pakistan. The agro-morphological study of wheat is important for the enhancement of yield production. Phenotypic correlation was calculated in all traits. Results indicated the number of grains per spike had positive and significant correlation to grain yield per spike. The days for maturity showed positive and significant correlation with plant height. The grain filling period indicated positive and non- significant correlation to days for maturity, spike length, grain yield per spike, plant height, number of grains per spike. Grain yield per spike had negatively non-significant correlation to harvest index. It is concluded from this study that most promising genotypes ESWYT-136, ESWYT-104, ESWYT-123, and SKD-1 were morphologically different from each other and are recommended for breeding programs and cultivation.
