Abstract
Variation in plant traits is considered as drivers of species evolution and of a greatest importance to plant breeders. The selection of the exotic wheat cultivars for high yield and their resistance to rust disease is of prime importance nowadays, which in result reduces the environmental impact and the total cost of lethal fungicides. Present study keeping the importance in view was carried to evaluate seven exotic wheat genotypes received from CIMMYT, Mexico; which were then compared to two local wheat cultivars (control). Significant (p<0.05) differences between the genotypes and control wheat cultivars were documented in terms of yield, yield related traits and resistance to the leaf rust disease. Cultivar G-193 not only appeared with higher yield but also had lowest AUDPC%-days values, demonstrating its higher resistance to the rust diseases. The study hence concludes with strong recommendations for cultivation of Cultivar G-193 among other cultivars.

Highlights
The selection of genotypes with wide range of adaptability to different climatic conditions with more high yielding traits i.e. tillers per plant, spikelets per spike, number of grains per spike and grain weight per spike has an prime importance in carrying a successful wheat breeding program [1, 9. 10, 11]
The experimental plant material consisting of seven wheat genotypes i.e. G-186, G-187, G-188, G-189, G-191, G-192 and G-193 were acquired from CIMMYT (Mexico) by Institute of Plant Sciences, University of
Morphological characteristics The results of ANOVA revealed significant differences (p≤0.05) for morphological, yield and yield related attributes and are in harmony with the results published by Baloch et al [3], who observed considerable genetic variations regarding yield and its associated traits among 19 exotic wheat cultivars under agro-ecological condition of Tandojam, Sindh, Pakistan
