Abstract: The performance of ten biblends, each grown in a 1:1 genotypic ratio was compared with the performance of the involved five bread wheat genotypes grown in pure stands. Land Equivalent Ratio (LER) was calculated by using the concept of de Wit and van den Berg (1965). Most of the biblends exhibited reduction in biomass and grain yield per plant than their respective mid component of pure stand. However, two biblends, Rohtas 90 - Chakwal 86 and 6500 - Chakwal 86 showed significant increase of 9.40 and 16.36 percent for biomass yield (LER values of 1.10 and 1.16) and 14.26 and 18.73 percent for grain yield per plant (LER values of 1.15 and 1.19), respectively. It was concluded that varietal mixtures do have potential as a means of increasing crop yield but identification of correct genotypic combination is essential.
