Food security is a pressing issue globally. The burgeoning world population is estimated to increase to 8.5 billion by the year 2025. It would demand food supplies which are to be doubled to meet the needs (Mujeeb-Kazi and Rajaram, 2002). Among the agricultural crops,wheat is of utmost importance as it is a source of feeding the major proportion of the world population. Wheat improvement, like any other crop, has relied on genetic diversity for enhancing its productivity. Several types of genetic resources such as landraces, wild progenitors, and translocations and substitution lines carrying alien segments are promising to augment the genetic diversity in bread wheat cultivars.
