Abstract

The experiment was conducted to find out the resistant varieties/lines against clubroot and Alternaria leaf spot diseases of mustard at the Plant Pathology Division, RARS Jamalpur, Bangladesh during the Rabi season of 2024-2025 with sixty-two (62) varieties and lines of Mustard collected from Oilseed Research Centre (ORC) and Plant Genetic Resources Centre (PGRC), Joydebpur, Gazipur-1701, Bangladesh. To screen for clubroot and Alternaria leaf spot diseases and to evaluate yield and yield-contributing characteristics, sixty-two mustard varieties and lines have been studied. Twenty-one varieties and lines among them exhibited 1.05 to 12.48% clubroot infected plants. Based on the disease severity scale, out of 62 varieties and lines, 41 had no clubbing, 10 had a few minor clubs, 9 had moderate clubbing, and 2 had severe clubbing. According to these results, the defense mechanisms of sixty-two mustard varieties and lines against clubroot disease vary in severity. Seed yield per hectare ranged from 455.60 kg to 2972 kg. The highest seed yield per hectare (2972 kg) was noted in Mustard BD-9955, followed by Mustard BD-9352 (2733 kg), Daulat (2670 kg), Mustard BD-9345 (2328 kg), Mustard BD-9340 (2106 kg), and the lowest in Mustard BD-9956 (455.60 kg). Additionally, a screening for Mustard Alternaria leaf spot was performed. Alternaria leaf spot disease severity ranged from 0.00 to 6.67% among 62 mustard varieties and lines.

Keywords: Mustard Varieties and Lines, Clubroot and Alternaria Leaf Spot, disease incidence (%), disease severity (%), disease severity status, seed yield (kg/ha).
