Abstract: Cotton leaf curl disease occurred throughout the province of Punjab during the year 1996, but there were patches where it was less severe and other patches where it was very severe. Nine varieties were planted in Mian Channun project area. CIM-240 was predominant variety through out cotton growing region of the Punjab There were varietal differences in both incidence and severity. To eliminate the possibility of varietal effects on the spatial pattern, kriging was done with only those fields planted with CIM-240. There were not enough points to give a broad coverage of the area, but the basic spatial pattern of incidence was the same as when all varieties except CIM-1100 are included in the analysis. Any influence of variety was evidently randomly distributed across the landscape so that the spatial pattern of the disease on CIM-240 was similar to the spatial pattern on all the varieties combined. This might not always be so in years when there are strong regional differences in the selection of varieties. There was a strong correlation (r = 0.962) between incidence and severity and the spatial pattern of severity was quite similar to that of incidence.
