Screening of Mustard Cultivars/ genotypes against systemic infection caused by Albugo candida(Pers. Ex. Lev.) Kuntz

Abstract

Indian mustard is an important oil seed crop of India. Many factors are attributed to its low productivity. Among them White rust/white blister of mustard is most important. In the present study 47 genotypes were screened against white rust under natural conditions during the Rabi season 2020-21. The categorization of mustard cultivars have been carried out on the basis of percent stag head formation using a 0-9 scale. Out of 47 genotypes two (PM26 &ChhutkiSarsho) were found resistant, 12 (NRCHB101, JM3, Kalawati, Local2, DRMR1665, Farm Sona, Pusa Vijay, Karuna, Super Kala Sona, Super Maha Gold G9, Maya & RH406 ) were moderately resistant, 18 (Rohini, Mahiko, RGN73, Rohini, PM28, Gold Star, Local1, PM30, US126, Pusa Mahak, Pusa Tarak, Mustard2541, RVM3, Kaalia, PM0031, Radhika, Vasundhara & Basanti) were susceptible and 15 (Varuna, Divya203, NRCDR02, Kala sona, PM11, Pusa26, PBR210, YBH402, DRMRIJ31, DRMR150-35, Ganga, RH0119, Sej02, MS2, Pitambari) were found highly susceptible. None of the genotypes were found to be Immune or highly resistant.
