The genetics of resistance against rust disease caused by Melamspora lini in linseed or flax was studied in F1, F2, BC1 and BC2 generations of a susceptible variety T-397, crossed with a resistant variety Surbhi. On the basis of the segregating ratio obtained in F2 and backcross generations of the cross, T-397 × Surbhi ., (3:1) in F2 and (1:1) in BC1 revealed that single dominant gene is responsible for resistance against rust in these linseed genotypes under study. | Inheritance of gene conferring resistance to rust (Melampsora lini) disease of linseed (Linum usitatissimum L.) in North West Himalayas
