National Symposium on Strategic Issues in Plant Pathological Research held at Department of Plant Pathology, CSK HP Krishi Vishvavidayalaya, Palampur on November 24–25, 2011
The MYMV resistant genotypes were screened during Kharif 2008, 2009 and 2010 at various locations in Himachal Pradesh i.e. Dhaulakuan (MYMV, anthracnose and powdery mildewPM), Palampur (Anthracnose and PM) and Bajaura (Cercospora leaf spot, CLS). One hundred genotypes were free from MYMV whereas, 17 genotypes were resistant (DR=2–3) to MYMV. None of the genotypes were free from anthracnose and Cercospora leaf spot. Genotypes IC 11668, IC 53020, IC 61092, IPU 99–374, JB 233, JBT 32/82, PLU 1016, MS/31, PLU 1025, PLU 363, PLU 493, PLU 557, TU 95-1, UC/TRC 1401 and VB 17 with disease reaction ‘2’ were highly resistant to anthracnose whereas, genotypes IP 01–376, IPU 99–213, JKU 98-3, PLU 190, PLU 197, PLU 223, PLU 552, SDC 3175 and UG 407 with disease reaction ‘3’ were resistant. Genotypes IPU 244, IPU 2K 21, IPU 99–192, IPU 99–229, IPU 99–23, NDS 341, PLU 3435, PLU 874 were moderately resistant to Cercospora leaf spot. Eight genotypes i.e. IC 131044, PLU 710, GAR J 209, IC 343936, UTTARA, PDU 1, PLU N716 and IPU 99–266 were free from powdery mildew (PM) whereas, genotypes G 163, 48C-T4, PLU 461, V 20/35, CN 806, IC 336975 and SK 44 with disease reaction (1–1.5) were highly resistant. Genotypes IPU 244, IPK 2K 21 and, IC 131044, PLU 710, IC 343936 showed multiple resistance to MYMV and CLS and, MYMV and PM, respectively. However, combine resitance to two or more than two pathogens was noticed in number of test accessions
