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.

    Studies on host-pathogen interaction and epidemiology of stripe rust of bread wheat incited by Puccinia striiformis f. sp. tritici West.‖

    The experiment entitled, ―Studies on host-pathogen interaction and epidemiology of stripe rust of bread wheat incited by Puccinia striiformis f. sp. tritici West‖ was conducted at CCS Haryana Agricultural University (CCS HAU), Hisar and ICAR-Indian Institute of Wheat and Barley Research, Karnal and its Regional Station, Flowerdale, Shimla., during Rabi season of 2022-23. In present investigation, eleven genotypes and four varieties namely, SABWGPYT-2005, SABWGPYT-3017, SABWGPYT-1015, SABWGPYT-2041, SABWGPYT-1009, SABWGPYT-1004, SABWGPYT-1026, SABWGPYT-1039, SABWGPYT-2044, SABWGPYT-2040, SABWGPYT-1010, WH1270, WHD948, WH896 and WH1124 showed higher degree of slow rusting/adult plant resistance. There were 31 genotypes and 1 variety which showed promising slow rusting/adult plant resistance to stripe rust at field conditions of Karnal and Hisar. Four wheat genotypes and one variety namely, SABWGPYT-2046, SABWGPYT-1009, SABWGPYT-1004, SABWGPYT-2016 and WH896 were found very resistant to pathotypes (46S119, 110S119, 110S84 and 47S103). A total of one hundred ten wheat germplasm were screened for 44 Yr genes with 54 specific linked Primer sets. Among 44 Yr gens, 32 genes were amplified the loci associated with Yr genes. Genes, Yr32 (0.9%), Yr18 (1.81%), Yr65 (4.54%), Yr36 (5.45%), Yr44 and Yr61 (6.36%) and Yr57 (10%) showed low frequency in wheat germplasm, while Yr5 and Yr35 (95.45%), Yr64 (92.72%), Yr46 (91.91%), Yr7 (89.09%), Yr67 (88.18%), Yr51 (86.36%) and Yr62 (85.45%) were most frequent in wheat germplasm. Temperature greatly influenced the stripe rust urediospores germination. The maximum per cent spore germination was 62.44, 56.72 recorded in case of pathotype 46S119 and 110S119 respectively at 12°C and it was 56.28 per cent for pathotype 110S84 at 15°C. Weather parameters significantly influence the stripe rust development and rust progress was greatly affected due to temperature, relative humidity and rainfall. In month of February maximum development of stripe rust was observed at Karnal and Hisar. The positive correlation of stripe rust severity was observed with temperature (maximum and minimum), relative humidity (evening) and total rainfall. Regression analysis indicates the variability in stripe rust severity up to 87 percent with average temperature at Karnal and 85 percent at Hisar, respectively.
