Durum wheats are reported to carry leaf rust resistance genes which are different from the Lr genes identified in Triticum aestivum and very effective against highly virulent races prevalent in the Indian sub-continent (Pasquini et al 1979; Sharma et al 1986; Roelfs, personal communication). These genes can be used to broaden the genetic base of leaf rust resistance in bread wheats. Although successful transfer of genes from durum wheats have been achieved earlier for the improvement of Triticum aestivum (McIntosh et al 1967; McIntosh and Dyck 1975), an altered expression of some genes due to change in ploidy level has also been reported (Kerber 1983; Dyck 1987). We report here the transfer of resistance from two highly resistant durums CPAN 6051 and CPAN 6073 to a susceptible hexaploid wheat Agra Local and comparison of the hexaploid derivatives with two commonly grown hexaploid wheats.
