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.

    Screening of wheat genotypes for multiple fungal resistance using functional markers
    (CCSHAU, Hisar, 2021-09) Garg, Bharat; Yashveer, Shikha
    In the present study, 58 wheat genotypes were characterized for grain yield, biochemical traits and functional markers. The wheat genotypes were sown in RBD (Randomized Block Design) design in two replications in the field of Wheat and Barley Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar, Haryana (India) during Rabi, 2019-2020 for the evaluation of ten yield and its component characters viz. plant height, number of tiller per meter, spike length, number of grain per spike, number of spikelet per spike, grain yield per meter, biological yield per meter, harvest index and 1000-grain weight. In this study 58 wheat genotypes were screened for morphological and biochemical traits, showed varied mean range signifying ample amount of variability present in the wheat genotypes Genetic variability of genotypes was assessed by PCV, GCV, heritability and genetic advance over mean. The values of GCV were lower than their corresponding PCV for all the characters studied, indicated the negligible effect of environment on the development of plants. The maximum value of the GCV & PCV was observed for the grain yield per meter (11.87) and number of spikelet per spike (16.65). Highest broad sense heritability was recorded for biological yield per meter (80.92) The positive and significant genotypic correlation for grain yield per meter was found with number of tillers per meter (0.503), spike length (0.217), number of grains per spike (0.332), biological yield per meter (0.864), harvest index (0.616). Thus, these component traits may be used in wheat breeding programme for further improvement in grain yield. For characterization of quality traits, various biochemical attributes were analyzed viz. total phenolic content, total flavonoids, proline content, glycine betaine, phenylalanine ammonia lyase (PAL) and tyrosine ammonia lyase (TAL) at vegetative and maturity stages. Total phenolic content range for vegetative stage is 0.41 to 4.74 mg CE/g and 1.07 to 6.17 mg CE/g in the maturity stage. Total flavonoids range for the vegetative stage, is 0.30 to 0.97 mg QE/g and 1.07 to 9.18 mg QE/g in the maturity stage. Proline content range for vegetative stage is 0.07 to 0.45 mg /g and 0.08 to 0.55 mg /g in maturity stage. Glycine betaine range for vegetative stage is 0.59 to 9.59 mg /g DW and 2.67 to 4.24 mg /g DW in the maturity stage. PAL activity range for vegetative stage is 4.15 to 6.23 μmole/h/g and 4.99 to 6.51 μmole/h/g in the maturity stage. TAL activity range for vegetative stage is 1.45 to 12.43 μmole/h/g and 1.74 to 12.10 μmole/h/g in the maturity stage. Total flavonoids content had high GCV and PCV in biochemical traits. On heritability analysis, Tyrosine ammonia lyase (TAL) had higher heritability. High heritability coupled with high genetic advance was found in characters such as total phenolic content, total flavonoids content, proline content, glycine betaine and TAL. These characters are recommended in selecting genotypes for screening for biotic and abiotic stress. For functional marker analysis, a total of 24 functional markers were used showed amplification. These selected primers are linked with specific fungal disease resistance gene and amplification of specific primer on wheat genotypes gave the idea of presence of that allele.
