Abstract
Correlation and regression studies on intensity of leaf diseases and grain yields have been carried out in 5 varieties of sorghum. A negative correlation existed between disease intensity and grain yields. The lowest negative regression coefficient was found in variety CK 60 B 1·63, 0·198 followed by 302 4·27, 1·01; Pila amla 5·7; PJ 4 K 10, 0·77; and Vidisha 60-1 25; in increasing order. The maximum loss sustaining ability was exhibited by 302 (55 and 37·96%), followed by Pila amla (31·01%), PJ 4K (26·46 and 19·28%), CK 60 B (23·10 and 20·16%) and Vidisha 60-1 (12·20%) in decreasing order.
