Abstract
This research work was performed to evaluate the performance of six wheat varieties including Mehran, TD-1, Kiran, Moomal, TJ-83 and Khirman for yield and its associated traits during 2013-14at Botanical Garden, Department of Plant Breeding and Genetics, Faculty of Crop Production, Sindh Agriculture University Tandojam. All the varieties were also examined for correlation coefficient among yield and its interlinked characters. The results revealed that yield and its associated traits of wheat varieties like plant height, grains spike-1 , spike length, spikelets spike-1 , seed index and grain yield plant-1 differed significantly (P0.05). The variety Mehran-89 produced plants of maximum height (96.81cm), spikelets spike-1 (20.45), grains spike-1 (62.95), tillers plant-1 (5.80) and grain yield plant-1 (9.18 g), and spike length was maximum (11.94 cm) in Kiran-95, while the value for seed index was highest (23.51 g) in variety TD-1.The correlation coefficient for yield and its contributing traits of wheat varieties showed a positive and significant (P < 0.05) association of plant height and grains spike-1 (r = 0.5541); spike length v/s spikelets spike-1 (r = 0.5986), spike length v/s grains spike-1 (r = 0.6667), spikelets spike-1 v/s grains spike-1 (r = 0.5592) and tillers plant-1 v/s grain yield (r = 0.8145); while negative and significant (r = - 0.5085) correlation was calculated between plant height and seed index.
