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.

    Twin Study on Empirical Intervention to Unravel Nature and Nurture of Intelligence
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-09) Annu; Dhanda, Bimla
    The aim of present twin study was to assess the influence of genetic and environment on intelligence of twins. A sample of 150 pairs of twins in the age groups of 3-6 years was attained from 55 villages of Bhiwani district and Hisar district of Haryana state. Intelligence of twins was assessed with help of Stanford Binet Intelligence Scale (Terman and Merrill, 1960), whereas home environment of twins was assessed by using the Home Observation for Measurement of the Environment (HOME) (Caldwell and Bradley, 1984) and preschool environment of twins assessed with the help of Early Childhood Environment Rating Scale (Thelma et al. 2005). The findings on heritability estimates showed that the influence of genetic on intelligence of twins was more than the environment in both districts. The results of heritability estimates also revealed that the contribution of genetic on intelligence of twins was more in the age group 5-6 years followed by 4-5 years and 3-4 years. The significant associations of intelligence were found with the variables, namely, mother‘s education and occupation, father‘s education and occupation, family size, family income and caste of twins boosted the intelligence of twins. The preschool environment of twins was also significantly associated with intelligence of twins in both Bhiwani and Hisar district. The intervention programme was also enhanced the intelligence of twins from 3-6 years in both Bhiwani and Hisar district. The twin research clearly concluded as the influence of genetic on intelligence of twins was more as compared to environmental factors and impact of genetic increases with increase in age of twins. Home environment of twins was also influential factor for the development of intelligence in twins of both districts.

    Biochemical changes in genetic and induced systemic resistance due to infection of Albugo candida (Pers. ex. Lev) in Indian mustard
    (CCSHAU, Hisar, 2020-03) Annu; Rathi, A. S
    White rust disease incited by Albugo candida is an important disease of Indian mustard (Brassica juncea) in India particularly in northern and North eastern states. Keeping in view the enormous losses caused by the pathogen, the present investigation has been devised on biochemical changes due to infection of Albugo candida in different Indian mustard genotypes, induction of systemic resistance by non conventional chemicals, identification of slow white rusting genotypes and role of micronutrients in defence against white rust under laboratory, screen house and field conditions at Chaudhary Charan Singh Haryana Agricultural University, Hisar. The results of biochemical analysis revealed that total phenolic content, PO, PPO, PAL and chitinase activity were found higher in healthy leaves of resistant genotypes (BIOYSR, EC399299) as compared to moderately resistant genotypes (EC399301, DRMRIJ-31) and susceptible genotypes (RH 30, RH 8812) at 35-40 DAS. There was steep increase in all the biochemical constituents at the time of disease initiation ie. at 45-50 DAS. However, increase was more in inoculated environment as compared to uninoculated environment. At maximum disease severity i.e.70-75 DAS, there was decline in all the biochemical constituents in all genotypes under both the environments. Decrease was more in susceptible genotypes indicating the exhaustion of these biochemical constituents which otherwise consider necessary to trigger genetic resistance through pathways. Efficacy of six non conventional chemicals were tested with different concentrations for induction of resistance against white rust. None of the non conventional chemical completely controlled the white rust disease even at higher concentration of 100 μg/ml. However, a maximum control was also recorded by BTH at 100 μg/ml concentration after six weeks of challenge inoculation by the pathogen followed by SA in both the variety (RH 30 and RH 0749) under screen house conditions. BTH has shown maximum induction of phenolic content, PO, PPO, PAL and chitinase activity at three days after inoculation (DAI) in both the varieties at 100 μg/ml concentration followed by SA. However, MgSO4 has shown minimum induction of these activities at three DAI in both the varieties.Out of 22 Indian mustard genotypes screened for identification of slow white rusting component, 9 genotypes exhibited longer incubation and latent periods, minimum number of pustules per leaf, minimum size of pustule, minimum sporulation, minimum disease severity and minimum AUDPC indicating slow white rusting behaviour. Among the different treatments of mcronutrients alone and in combinations, soil application of Gypsum + Borax + CuSO4 + Na2MoO4 at 30 DAS as basal dose recorded minimum white rust severity of 31.1% and staghead incidence of 4.44% and highest seed yield of 2228.55 kg ha-1 as compared to the 45.83% white rust severity and 6.09% staghead incidence and seed yield of 1779.79 kg ha-1 in control. Maximum number of primary branches per plant (5.83), secondary branches per plant (12.33), main shoot length (90.93 cm), siliquae on main shoot (62.60) and seeds per siliquae (12.53) were also observed with above treatment. Plant height, siliqua length, oil content and 1000 seed weight did not vary significantly among all the treatments.
