Evaluation of Elite Sorghum Accessions for Multiple Disease Resistance
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.

The international crops research institute for the semi-arid tropics
Abstract The semi-arid regions of the world are spread over 48 countries on four continents and cover a total area of nearly 20 million square kilometres. About 500 million people live there. Modern technology has only lightly touched the farmer of the semi-arid tropics. He uses little fertiliser; the soils he tills are often eroded and depleted of nutrients. The power he uses almost always is animal or human. His own productivity and that of his animals is generally low for a number of reasons, including disease and undernourishment. The most restrictive of his natural resources is water—limited in amount and distributed during a short rainy season in unpredictable and frequent heavy downpours. ICRISAT was created to help the 500 million people of the semi-arid tropics. The initials stand for the International Crops Research Institute for the Semi-Arid Tropics. The Institute was started in 1972 and is located at Hyderabad, India, centre of the semi-arid tropics.
