The goal of the study was to determine whether the heterotic influence and phenotypic link between a numbers of yield variables in F1 hexaploid wheat hybrids could be controlled (Triticum aestivum L.). Our research trail was held at the Botanical Garden of Sindh Agricultural University's Department of Plant Breeding and Genetics in Tandojam, Pakistan. Six parental varieties (Sunhri, PBGST2, Sarsabz, TD1, TJ83, and Moomal) and nine F1 hybrids (TJ83 x TD1, PBGST2 x TD1, TJ83 x Moomal, TD1 x Moomal, TD1 x Sarsabz, Sarsabz x Sunhri, and TJ83) were supplied with material seed by the Department of Plant Breeding. After eight characters were evaluated, the experimental fields were selected and put into a randomised complete block design with four repetitions. The hybrids differed considerably (P 0.01) for every trait examined with the exception of plant height and maturity up to 75% of the time, whereas the parents showed no differences in grain yield. There was significant heterosis in the F1 hybrids, as seen by the mean square of the parent and the hybrid. Overall, maturity was important up to 75% of the time, even if it was negatively correlated with the majority of production metrics, meaning that genotypes with early maturation produced lower yields. The spikelets spike-1, seed index, and harvest index in plant-1 were all adversely connected with plant height, however grain yield was significantly and favourably correlated with all yield indices. These findings showed that choosing plants that produce more grain could be based on one or more yield components.
