Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Biochemical and molecular attributes of the diverse genetic pool of Brassica juncea var. rugosa (pahari rai) for identification of elite germplasm having potent bioactivity
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) Adhikari, Ankur; Punetha, Himanshu
    Brassica juncea var. rugosa (pahari rai), a broad leafy cruciferous vegetable is an essential and easy source of nutrition with numerous health-promoting factors. Eighteen different germplasms of Pahari rai and two checks (Pusa saag and Kranti) have been cultivated during seasons 2019-20 and 2020-21. Germplasm had totally different selected agro-morphological traits. PCA analysis depicted that PC1 (35.25%), PC2 (18.71%) and PC3 (17.09%) contributed to the morphological variability among the germplasms for the traits under study. Tocher method divided all germplasms into four different clusters as per morphological characters. A biplot between PC1 & PC2 showed, germplasm IC-399826 is within the ace of origin were more stable and less diverse, whereas IC-597821, IC- 298019 and IC-276011 are away from the origin, which were less stable and more diverse. Genetic diversity and population structure of cultivated germplasms using 100 SSR primers subjected to Darwin 5 software. A total of 74% SSRs resulted in polymorphic amplicons. UNJ-based dendrogram grouped all the 18 germplasm along with two checks into two distinct clusters. PCA of genetic diversity showed that the first and second principal components accounted for 29.25% and 14.7% of the total variation. Phytochemical and antioxidant activity of leaf extracts showed the highest phenolic (6.45±0.045 mg GAE g-1), flavonoid (6.32±0.06 mg QE g-1), ODP (4.66 ± 0.52 mg CE g-1) and tannin (3.46 ± 0.02 mg tannic acid g-1) content were observed in the EEC-25 leaf methanolic extract. The highest protein content in EEC-25 (400.97±16.5 μg QE g-1) followed by IC-524259 (380.09±17.22 μg QE g-1) and IC-350800 (379.23±18.26 μg QE g-1). The foremost concentration of carbohydrates was observed in germplasms IC-363758 (31.47±0.31 mg glucose g-1), IC-410471 (31.12±0.18 mg glucose g-1) and EEC-25 (26.45±0.19 mg glucose g-1). In-vitro antioxidant potential viz., total antioxidant content was observed highest in EEC-25 methanolic leaf extract (41.91±0.28 mg AAE g-1), FRAP activity in EEC-25 (5.91±0.68 mg AAE g-1), maximum DPPH free radical scavenging activity in IC- 597933 (IC50=21.45±3.4 μg mL-1), ABTS free radical scavenging activity in IC-524259 (94.17±0.48 μg mL-1), superoxide radical scavenging activity of methanolic extract of PR-15 (IC50=124.37 μg mL-1), highest metal ion chelating activity of EEC-25 methanolic extract (IC50=52.22 μg mL-1), maximum reducing power activity in EEC-25 and IC-399839, all being significantly different (p≤0.05) from each other. Positive correlations have been observed among the total antioxidant, total phenolic, total flavonoid content, ODP, DPPH and FRAP. Pahari rai was observed to be a rich source of MUFA and PUFA. An essential metric for assessing the nutritional value of various edible oils is the ω6:ω3 ratio was observed to be maximum in IC-350800 (2.53), IC-338535 (2.34) and IC-410471 (2.19). Micronutrient analysis Pahari rai leaf observed to be the rich source of essential minerals such as Mn, Fe, Zn, Ca, Cu and Mg. The anti-inflammatory activity among the elite accessions the IC-350800 (IC50 =25.19±1.06 μg mL-1) was observed to be the maximum. No zone of inhibition was evident against selected human pathogenic bacteria using methanolic leaf extracts of elite accessions of Pahari rai. Invitro cytotoxicity in MDBK and Vero against the selected methanolic leaf extracts (IC-524259, EEC- 25, IC-597933, IC-350800 and Pusa saag) was non-significant. Results clearly revealed the presence of significant amounts of phytochemicals, antioxidant activities and in vitro anti-inflammatory activities in leaves of Pahari rai. The multiutility of this leafy vegetables against numerous pathological ailments was attributed to pharmacological activities of phytochemicals and for the development of functional food for human consumption.
