Abstract

The analysis of harvested grain samples of wheat grown in different agroclimatic zones of India was done at Karnal and other cooperation centre from 1991–92 to 1994–95 crop seasons. A total, 18,895 samples of grains from farmers' fields and grain ‘mandles’ and about 4,000 samples from experimental fields were collected and examined for the presence of Karnal bunt and black point infected grains. The incidence of Karnal bunt varied in different agroclimatic zones and wheat srains from states like Karnataka, Maharashtra, Gujarat, Bihar, Assam, Manipur, higher hills of Uttar Pradesh (Now in Uttaranchal) Himanchal Pradesh (except Poanta valley) were free from Kamal, bunt whereas low incidence was detected in Madhya Pradesh, Rajasthan, southwestern Haryana, Delhi and western Uttar Pradesh except farm districts (0.01–17.2%). The samples collected from experimental fields had lower percentage of infected samples as compared to those collected from farmers' fields and rnandies. The grain samples collected from states like Karnataka, Maharashtra, Gujarat, Bihar and higher hills of H.P. and U.P. (now Uttaranchal were found free from Karnal bunt from 1991–92 to 1994–95 crop seasons in spite of the fact that seeds from the endemic areas like Haryana and Punjab was planted in these states thus indicating presence of unfavourable weather conditions for Kamal bunt development (warmer temperature and dry conditions) at flowering stage of wheat. The black point was present in all the states but its incidence was higher in the states having warmer and dry weather as compared to hilly regions.
