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.

    Morpho-molecular characterization and hybridization studies in peach [Prunus persica (L.) Batsch
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Rajender Kumar; Dimri, D.C.
    The present investigation entitled “Morpho-molecular characterization and hybridization studies in peach [Prunus persica (L.) Batsch]” was performed at HRC, Patharchatta, G. B. Pant University of Agriculture & Technology Pantnagar and MBGE Laboratory of UCB, Haldi, Pantnagar, U.S. Nagar, Uttarakhand from January, 2021 to June, 2022. The whole study was completed in 3 different experiments. In the 1st experiment the low chill peach cultivars (12 Nos) maintained at HRC, Patharchatta were estimated for their morphological and biochemical characters. In the 2nd experiment the same peach cvs. as well as the high chill peach cvs. (29 Nos) collected from ICAR-NBPGR (RS), Bhowali, Nainital were characterized at molecular level. While, in the 3rd experiment the hybridization studies among selected low chill peach cultivars were carried out at HRC, Patharchatta and further hybridity was tested at MBGE Laboratory, UCB, Haldi. The results showed adequate amount of genetic variability among the different cultivars of low chill peaches. The fruiting characters namely; fruit length, diameter, weight and pulp: stone ratio varied from 39.14-66.30 mm, 32.82-62.63 mm, 30.24 to 123.70 g and 9.47-23.41, respectively. The ranges of total soluble solids (10.34-13.61 °Brix), titratable acidity (0.44-0.98%), ascorbic acid (9.58-14.58 mg/100g), total sugars (8.69-12.06%), anthocyanin (0.33-2.33 mg/100 g), total phenols (29.16-68.67 mg GAE/100g FW), flavonoids (6.79-61.90 mg/100 g) and antioxidant capacity (36.40-72.24%) was recorded among the various low chill peach cultivars. Among the various cultivars tested, Shan-i-Punjab was found to be most productive (20.52 kg/tree), while Saharanpur Prabhat estimated the highest yield efficiency (0.080 kg/cm2). Genetic diversity among 41 genotypes of low and high chill peaches was examined with 25 SSR primers, which indicated that beside two markers all showed polymorphism, resulted into 108 polymorphic bands. The highest polymorphic information content (PIC) was revealed by SSR marker BPPCT 033 (0.770) and lowest by MA020a (0.337). Jaccard’s similarity coefficients varied from 0.537 to 1.000 with an average value of 0.739. Among the 41 genotypes, the IC-360682 and IC-360683; IC-360691 and IC-360680 and; Totapari and IC-247431 were found to be the most similar with a similarity coefficients of 1.0, however, the minimum Jaccard’s similarity coefficient was found between IC-209014 and Red June (0.537). In hybridization studies, crosses were made between selected low chill peach cultivars. The maximum fruit set (76.74%) was noted for hybrid H2 (Saharanpur Prabhat × Pratap) and minimum (55.93%) in H5 (Sharbati Surkha × Pratap). Maximum fruit retention was registered in hybrid H4 (Sharbati Late × Florida Red) i.e., 71.15%, whereas, hybrid H2 showed minimum fruit retention (39.85%). Among 25 markers employed for hybridity confirmation, only 3 primers set (CPPCT-022, UDP96-005 and UDP98-407) were able to confirm the hybridity of the F1 seedlings. The cultivars identified to be promising in the investigation may prove to be potential genetic resource in low chill peach improvement programme. Further, SSR diversity may be used as a criterion for selection of parents in the improvement of peach using hybrid breeding programme.
