Evaluation of linseed germplasm for resistance against rust (Melampsora lini): EVALUATION OF LINSEED GERMPLASM FOR RESISTANCE AGAINST RUST

Two hundred germplasm lines of linseed were screened against rust disease caused by Melampsora lini at two hot spot locations viz., Kangra, Himachal Pradesh and Kanke, Jharkhand for three consecutive rabi seasons of 2011-12 to 2013-14. Thirty four entries were highly resistant, 21 were resistant, 19...

Description
Summary:Two hundred germplasm lines of linseed were screened against rust disease caused by Melampsora lini at two hot spot locations viz., Kangra, Himachal Pradesh and Kanke, Jharkhand for three consecutive rabi seasons of 2011-12 to 2013-14. Thirty four entries were highly resistant, 21 were resistant, 19 were moderately resistant, 12 were moderately susceptible and rest of them were susceptible to highly susceptible to rust against the naturally occurring races of Melampsora lini in the Kangra valley of Himachal Pradesh. At Kanke, out oftwo hundred entries evaluated, thirty seven entries were highly resistant, 27 were resistant, 28 were moderately resistant, 23 were moderately susceptible and remaining were susceptible to highly susceptible to rust. Twenty genotypes namely Jabalpur local, KP-13B, Mayurbanj local, MS-3, OP-2-2, Polf-2, Polf-16, KL-1, LC-2014, LC-2127, LCK-9119, LCK-9303, LCK-9320, LCK-9324, SJKO-10, EC-384154, H-43, H-5, ES-44 and LC-2002 had disease score of 0at both the locations and were rated as highly resistant.
