Evaluation of elite sorghum accessions for multiple disease resistance uri icon

abstract

  • Several plant diseases reduce grain and fodder yields of sorghum (Sorg/jum bicolor) and its stover quality (Bandyopadhyay et al. 2001). Participatory rural appraisal studies In India by Rama Devi et al. (2000) Indicated that sale of crop residues to perl-urban milk producers accounted for approximately 50% of the income from sorghum cropping In rural areas of the Deccan Plateau of Andhra Pradesh, Karnataka and Maharashtra, and diseased residues command much lower price In the fodder market. Adverse effects of foliar and panicle diseases on quality and quantity of sorghum grain, fodder and residues have recently been reported (Bandyopadhyay et al. 2000, 2001). Most sorghum diseases can be effectively managed through host-plant resistance. The objective of this study was to Identify resistance to multiple diseases in the selected agronomic elite landrace accessions and breeding lines of sorghum. In this article we report both agronomic features and multiple disease resistance of some of the accessions for their possible use in resistance breeding program
