Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Variability, epidemiology and management of Tilletia indica Mitra, the incitant of Karnal bunt of wheat
    (CCSHAU, Hisar, 2019-11) Mamta; Rajender Singh
    Karnal bunt disease of wheat continues to be a potential threat to production and trade of wheat. The present study was planned to study cultural, morphological, molecular and pathogenic variability in Tilletia indica, epidemiology and management of this disease. On the basis of cultural and morphological characteristic, the largest teliospore size was observed in Bhiwani isolate, whereas Kapurthala isolate was having the smallest size. Different Karnal bunt isolates colony colour were white, yellowish white, creamy, creamish yellow and creamish white whereas, culture colony growth pattern of isolates were erect, compact, clustering, crustose, appressed, spreading and leathery. Maximum teliospore germination, primary sporidia formation and secondary sporidia production was recorded at 18°C in Pantnagar isolate. Best teliospore germination occurred at pH 6.0 followed by pH 5.0 Maximum coefficient of infection was expressed in HD2967 followed by DPW 621-50. Pantnagar isolate exhibited maximum mean coefficient of infection followed by Bhatinda and the least was observed in Mahendergarh isolate. Pantnagar isolate was most virulent as well as had maximum sporulation. Karnal bunt resistant reaction in three differentials namely HD 29, HD 30 and Aldan were noted. In molecular variability twelve molecular markers were tested against 10 Karnal bunt isolates and characterized into 3 major groups. Karnal bunt incidence had significant correlation with maximum temperature, rainy day and total rainfall during earhead emerging stage Two hundred seventy nine genotypes showed less than 5 coefficient of infection against Karnal bunt thereby expressing resistant reaction and 221 genotypes were susceptible having more than 5 per cent coefficient of infection under artificial inoculation condition. Maximum disease control was obtained by propiconazole 25% EC (0.1%) application, followed by combination of propiconazole 25% EC (0.05%), neem seed kernel and Trichoderma harzianum.
