On the basis of differential seedling reaction of HUW-12 and WH-322 against various brown rust races and comparing it with all the thirty Lr genes, the resistance genes present in these two varieties were postulated. Screening, of F2 seedlings derived from the crosses with susceptible Agra Local indicated the number of resistance genes present in these culuvars. The F2 population of crosses WH-322 × Lr10 and HUW-12 × Lr14a failed to segregate. It is concluded that HUW-12 has Lr14a and WH-322 has Lr1O, in addition to another unidentified Lr gene.
