Abstract: |
Cultivation of Brassica vegetables specially cauliflower and cabbage is one of the important income generating livelihood options to the farmers. Clubroot disease (Piasmodiophora brassicae Woronin) is causing huge losses in cabbage and cauliflower production. Use of resistant varieties is the easiest, safest and cheapest method to combat with disease. No resistant varieties against this disease have been identified yet in Nepal. During 2005 to 2007, seedling screening of different Brassica vegetables collected from local market and Agriculture Research Stations was conducted under screenhouse at Khumaltar. Likewise, during 2008-2010 a set often resistant cauliflower and cabbage hybrids from Syngenta Seeds were verified for seedling and adult plant resistance in screenhouse and in infested farmers' field at Bhaktapur. A scale of 1-6 was used for assessing the c/ubroot severity. Of the Brassicas evaluated. radish genotypes and broad leaf mustard cv. Marpha Chaudapat were found resistant. Cauliflower hybrids: Clopton A, Clap/on B, Clarify A, Clarify B and cabbage hybrids: Teki/a, Kilazol, Kilaherb, Kiloton and Kilaxy were found highly resistant (score I) while susceptible cauliflower check Milky Way scored more than 3. Cauliflower hybrid, Tetris was found moderately resistant. Marketable curd yield of those resistant hybrids of cauliflower and cabbage ranged from 22 to 39 Kg and 20 to 27 Kg per 5 m1 respectively. The use of those resistant hybrids could be the non chemical tool for the management of clubroot disease. However, seed should be made available in the market through concerned agencies. |
