Correlations Among Leaf Blight Resistant Parameters and Yield Contributing Characters of Sorghum

摘要

Sorghum, Sorghum bicolor (L.) Moench is the third most important cereal crop cultivated extensively in India after wheat and rice. Several destructive diseases affect sorghum grain and fodder yield and their quality. Recently, the occurrence of blightis widespread in tropical climates including India (Bandyopadhyay, 1999). The disease is prevalent and actively widespread particularly in the states of Andhra Pradesh, Haryana, Maharashtra, Madhya Pradesh, Karnataka, Tamil Nadu and Rajasthan (Sundaramet al., 1972). A disease intensity of 32 to 69 per cent (Anon., 1979) has been reported with a loss of 45 per cent in grain yield (Sharma, 1978).
