ABSTRACT
Cultivation of low genetic potential cultivars is one of the main factors which cause yield reduction in wheat. In this regard, the selection of new high yielding cultivars with better adaptability to local conditions is important for growth and yield associated traits. The highly varied performance of crop cultivars of the same species for growth and yield-related attributes is well documented. The present investigation investigated the performance of wheat cultivars under Tando Jam conditions. For this study, two-year field experiments were performed during October 2015-2017 (both seasons) applying randomized complete design with three replications. Performance of various wheat varieties for their yield and yield-related characters, including TD-1, Moomal-2002, Anmol-91, and Imdad-2005 were investigated. The results demonstrated that all the cultivars showed significantly varied performance for growth and yield-related traits. However, TD-1 and Moomal-2002 comparatively showed better performance for most of the investigated parameters. Cultivar Moomal-2002 performed better for vegetative traits viz; seed emergence (m-2), tillers plant-1, plant height (cm) and biological yield (kg ha-1). However, TD-1 proved to superiority in yield-related contributes such as spike length (cm), spikelets spike-1, grains spike-1, 1000 grain weight (g), and grain yield (kg ha-1) under both seasons. Among all cultivars, Imdad-2005 revealed the lowest values for all the scored traits. Based on the finding of the current study, it is concluded that the wheat cultivars TD-1 and Moomal-2002 performed better in terms of growth, yield, and yield characters as compared to the rest of the cultivars in both years. Therefore, wheat cultivars TD-1 and Moomal-2002 may be grown under the agro-ecological conditions of Tandojam, Sindh, Pakistan.
