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.

    Correlation and path analysis in tea [Camellia sinensis (L). O. Kuntze]
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Bhaskar, Jitendra; Roy, D.
    The field experiment was conducted on five varieties at Tea Research Station, Kausani, Uttarakhand to understand nature and magnitude of variation present among the tea germplasm and to characterize the different clones. Data were recorded on ten characters for each genotype. The phenotypic coefficient of variability was highest for surface area of bush followed by weight of the bud and number of plucking points but lowest for length of the 1st leaf of the shoot. Genotypic coefficient of variability was highest for surface area of bush followed by weight of the bud and number of plucking points and lowest for length of the 1st leaf of the shoot followed by width of 1st leaf of the shoot. 100 seed weight, length of mature leaf, weight of the bud and number of plucking points showed high heritability. The genetic advance was high for 100 seed weight followed by number of plucking points and weight of the shoot. Comparison of mean showed that T-78 Vs Kangrajat, BSS-449 Vs Kangrajat and UPASI-9 Vs Kangrajat, combinations are genetically diverse. Comparison of variance shows that AV-2 and Kangrajat are genetically diverse genotypes. Comparison of both mean and variance shows that AV-2 and kangrajat are genotypically most diverse genotypes. Correlation coefficients at the genotypic level reveal that only three pair of traits, namely, number of plucking points and weight of the shoot, surface area of bush and width of 1st leaf of the shoot, length of mature leaf and width of the mature leaf showed positive and significant phenotypic correlation. Surface area of bush showed negative and significant correlation with weight of the shoot. Path analysis revealed that only four traits, namely, length of the mature leaf, width of the mature leaf, number of plucking points, and width of the 1st leaf of shoot showed high, positive and direct effect on weight of the shoot. Correlation and path analysis revealed that in tea, traits, number of plucking points, length of mature leaf, width of mature leaf and width of 1st leaf of the shoot can be considered important for improving the weight of shoot in tea.

    Study of variability in tea [Camellia sinensis L. (o) kuntze]
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-07) Biswas, Subhrajit; Roy, D.
    The field experiments were conducted on eight genotypes at Tea Research Station, Kausani, Uttaranchal to understand nature and magnitude of variation present among the tea germplasm and to characterize the different clones and select the promising ones. Data are recorded on thirteen characters viz. for each genotypes. Sufficient genetic variation is there for twelve characters except width of the 1st leaf of the shoot. number of primary branches, number of secondary branches, surface area of bush, length of mature leaf, width of mature leaf, Leaf Area Index (LAI), weight of the shoot, weight of the bud, length of the shoot, length of the 1st leaf of the shoot, width of the 1st leaf of the shoot, 100 seed weight, number of plucking points. Number of primary branches, number of secondary branches, surface area of bush, weight of bud showed high phenotypic coefficient of variation. Number of primary branches, number of secondary branches, surface area of bush, weight of the bud, width of the 1st leaf of the shoot and number of plucking points showed high genotypic coefficient of variation. Number of primary branches, number of secondary branches, surface area of bush, length of mature leaf, width of mature leaf, weight of the shoot, length of the shoot, length of the 1st leaf of the shoot, 100 seed weight and number of plucking showed high heritability. Number of secondary branches and width of the 1st leaf of the shoot showed high genetic advance. Correlation coefficients at the phenotypic level reveals that eight pairs of traits showed high, positive and significant phenotypic coefficient of correlation. Among these three traits showed high, positive and significant phenotypic coefficient of correlation with the character number of plucking points. Path analysis revealed that number of secondary branches to be the direct contributors towards number of plucking points. Number of primary branches and surface area of bush also contributed indirectly towards number of plucking points. So number of plucking points can be increased by increasing secondary branches, surface area of bush and primary branches.

    Evaluation of f4 progenies of a wide cross involving mungbean (cv. BDYR-1) and blackgram (cv. DPU 88-31) for yield and yield components
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-06) Sharma, Hariom Kumar; Singh, D.P.
    The present investigation was carried out in Augmented Design during kharif season of 2005 with one hundred progenies of a wide cross (BDYR-1 × DPU 88-31), their parents and two checks (mungbean cv. Pant M-4 and blackgram cv. Pant U-35) at Crop Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttaranchal. The wide cross was made in kharif 2001. The observations were recorded on days to first flower, plant height, primary branches/plant, clusters/plant, pods/cluster, pods/plant, pod length, seeds/pod, 100-seed weight and grain yield/plant to study phenotypic variability, character association, genetic divergence and genetic relationship using SDS –PAGE. The ANOVA revealed highly significant genetic differences among check varieties for all the characters studied. In mungbean type of progenies the high values of P.C.V. were observed for grain yield/plant, clusters/plant, pods/plant and primary braches/plant while in case of backgram type of progenies high values of P.C.V. were noticed for cluster/plant, pods/cluster, pods/plant and seeds/pod. Amongst mungbean type of progenies only progenies no. 6 was significantly superior for cluster/plant. Amongst blackgram type of progenies, progeny no. 70 was significantly superior than best check for days to first flower, pods/cluster, pod length and seeds/pod. Character association study revealed highly significant and positive association of grain yield/plant with pods/cluster (0364) and pods/plant (0.364). Metroglyph and Index score analysis revealed maximum variability for different characters in fifth group which comprised of 60 progenies. The highest index score of 23 was observed for progeny no. 77. The protein profiling studies revealed genetic relationship among the progenies. Most of the progenies studied were generically different from their parents. Progenies showed parental type as well as recombinant type of bands Therefore, it can be concluded that transgresive segregants for important yield characters can be obtained by inter specific hybridization between mungbean and blackgram.

    Studies on genetic diversity, characters association, diseases and seed protein profiling of cowpea [Vigna unguiculata (L.) Walp.]
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-06) Madheshia, Sunil Kumar; Pandey, I.D.
    The present investigation was carried at Seed Production Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar, Uttaranchal, India during Zaid and Kharif seasons of 2005. The study was aimed to (1) evaluate the extent of genetic variability. (2) study the pattern of genetic divergence. (3) assess the nature and magnitude of correlation among different characters. (3) screening the cowpea lines for multiple disease resistance. (4) assess the genetic variation in the cowpea lines with help of SDS-PAGE (5) identify the germplasm lines, which may serve as potent donors for some important quantitative characters and qualitative characters. The experimental material was comprised of an accession of 51 advanced improved lines of cowpea (received from International Institute of Tropical Agriculture, Nigeria) and 1 commercial variety In Zaid season, seed yield per plant showed highest PCV (74.28%) followed by stover yield per plant (72.73%) while in Kharif season, stover yield per plant showed highest PCV (69.87%) and followed by number of pods per plant (60.29%) and seed yield per plant (56.26%). The clustering pattern in Zaid and Kharif seasons, 2005 revealed that the genotype pairs IT 98K-205-10 and IT 97K-461-4, Com.1 and IT 97K-461-4, Com.1 and IT 98K-205-10 were showing maximum divergence. Therefore, these pairs can said to be diverse pairs and hybridization between these may result into new recombinants of desirable types. In the present study, number of pods per plant and pod length were positively and directly related to seed yield per plant during both the seasons and may be considered as most important characters for seed yield improvement in cowpea through selection, as these characters have positive correlation among themselves besides the seed yield. On the basis of disease scoring, the genotypes IT 00K-1218, IT 99K-1056 and IT 97K-643-1 were found resistant against all the six diseases studied over both the seasons. In SDS-PAGE experiment, specific protein bands have been observed for different genotypes of cowpea. Therefore, SDS-PAGE techniques can be used for identification as well as determination of purity of genotypes/cultivars of a crop. This diversity in storage proteins provides the genetic basis for identifying the genotypes and used in several crop plants for determining the genetic identity and purity. The electrophoretic banding pattern of genotypes is used to discriminate the morphologically similar genotypes.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Budhalakoti, Neha; Tewari, Salil Kumar
    The present study was carried out in the Forest Genetics Lab, Department of Genetic and Plant Breeding. G. B. Pant University of Agriculture and Technology, Pantnagar, U. S. Nagar (Uttaranchal). Two species of Bamboo, Bambusa vulgaris (Green) and Dendrocalamus membranaceus were taken and micropropagation studies were made using nodal portion as explant. Two Factor Complete Randomized Design analysis was performed to find significance of data and means were taken to screen out treatments giving significant results throughout the study. For sterilization of the explant 0.1% of HgCl2 (Mercuric chloride) for 15 min was found to be the best for both the species then nodal segment were cultured on MS medium supplemented with (15-25 μM) BA for bud break, both the species showed maximum and significant bud break response at 25μM BA treatment. After subculturing the propagules were put for shoot multiplication and concentration of 15μM BA was proved to be the best for shoot multiplication. Shoot multiplication fold was found to be the best in the combination of BA and kinetin at (10μM BA + 15μM kinetin) treatment in Bambusa vulgaris and combination of (5μM BA + 15μM kinetin) was found to be the best in Dendrocalamus membranaceus. Combination treatment of BA and IAA at (10μM BA + 3μM IAA) was found to be the best for shoot multiplication in Bambusa vulgaris and concentration of (10μM BA + 2μM IAA) was found to be the best for shoot multiplication in Dendrocalamus membranaceus. In-vitro rooting was studied using different auxins viz. IBA, NAA and IAA where NAA at 20μM was found to be the best finally the plant with robust roots were taken for hardening.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Joshi, Dinesh Chandra; Roy, D.
    The present investigation was carried out during 2004-05 at Horticultural Research Centre, Patharchatta of G.B. Pant University of Agriculture and Technology, Pantnaagr. The experimental material comprised of a population of papaya. The objective was to study the variability in population. Observations were recorded on 63 selected plants for 9 plant and fruiting characters namely number of fruits per plant, fruiting length, height to first fruit, fruit weight, pulp thickness, fruit diameter, pul[p colour, cavity size and total soluble solids. Analysis of variance revealed significant differences among all the selected 63 plants for all the eight characters except pulp colour which was not analysed . Wide range of mean values for all the eight traits showed immense variability present in the population for these traits which provided scope for selection. Phenotypic correlation coefficients were calculated between eight pairs of traits on the basis of overall selected plants. Most of the characters were found positive and significantly correlated with each other. Cavity size was the trait which showed positive and significant correlations with other traits viz., fruit number, fruiting length, fruit diameter and total soluble solids. Phenotypic correlations which were calculated between five pairs of fruiting traits on individual plant basis showed almost similar results but some different results were also obtained.

    Biochemical and molecular characterization of wheat genotypes for biscuit quality
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Singh, Chitra; Jaiswal, J.P.
    Wheat is the dominant grain of world commerce. India ranks 2nd in wheat production in the world and is self sufficient. However, its share in export market is negligible. It has a great potential to emerge as a reliable exporter of what and wheat products provided serious emphasis is given on the development of product specific varieties. The present investigation deals with evaluation of 40 genotypes for biscuit making quality on the basis of different quality attributes viz. protein content (%) and sedimentation value (cc) and high molecular weight glutenin subunits (HMW-GS). Eighteen genotypes with protein content of < 11 % and sedimentation value of < 40 cc were found superior for biscuit making quality. SDS-PAGE analysis showed that Glu-1 score ranged fro 4-7 in low protein genotypes and subunit 2 + 12 at Glu-1 D locus appeared to be related with biscuit quality. Ten low protein genotypes were evaluated for biscuit spread ratio and RAPD pattern. Biscuit spread values and diameter values were obtained in the range of 5.1 to 8.3 and 7.2 cm to 8.3 cm respectively. RAPD analysis of ten low protein genotypes was done by using four random primers viz., UBC 552, UBC 535, UBC 337 and UBC 386. However, no primer was able to amplify unique loci and only primer UBC 552 gave polymorphic loci. Thus, primer specificity was essential to characterize wheat genotypes for the biscuit making quality at the molecular level.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Arora, Shakti; Singh, S.P.
    The experiment was conducted with 10 diverse genotype as female parents viz. RAURDL-02-01, PR-2001-65, RK03-1, Basanti, Bio (E)-2, PRQ-2003, Varuna, Pusabold, SEJ-2 and Bhagirathi and three testers viz. Kanti, B-85 and PR(B)-2003-6 as male parents at Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar. The parents and 30 F1s were evaluated in randomized block design with three replications for eighteen important quantitative traits. GCA and SCA variances were found to be significant for most of the characters. The higher magnitude of SCA than GCA exhibited involvement of non-additive give action for all traits. Pusabold, RAURDL-02-01 and Varuna were found to be best combiners. Majority of crosses showed moderate to high range of heterosis for all the characters. Economic heterosis was found maximum for seed yield per plant (200 to 215 per cent) and minimum for days to maturity (-6.65 to 7.612 per cent) in the desired direction. Economic heterosis was exhibited by all the crosses. PRQ-2003 Kanti, RK03-1 Kanti, and PR-2001-65 Kanti were best cross combiners obtained for seed yield per plant, earliness and oil content, respectively. The study resulted into the identification of cross combinations for desirable traits.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Singh, Rajendra; Pant, D.P.
    The experiment was conducted with seven diverse genotypes of Brassica compestsis var. yellow sarson viz. PYS-9808-1, PYS-2005, PYS-2009-1, YSBNC-1, MYSL-221, and YSCN-14& B-9 at Crop Research Centre, G.B.Pant University of Agriculture and Technology, Pantnagar. The parents and their 42 Fi's including reciprocals were evaluated for seventeen important yield and quality traits. The results revealed significant differences among genotypes for all the characters.Number of secondary branches per plant, number of siliquae per plant and stearic acid showed high GCV/PCV.High heritability in broad sense was observed for days to 50% flowering, days to 100% flowering, days to maturity, number of secondary branches per plant, number of siliquae per plant, leaf angle, number of seeds per siliqua, palmitic acid, stearic acid, oleic acid, linoleic acid., linolenic acid, eicosenoic acid and erucic acid. Highest genetic advance observed for number of secondary branches per plant and number of siliquae per plant. 1000 seed weight was significantly and positively correlated with number of siliquae per plant while negative correlation with days to 50% flowering and number of secondary branches per plant. Number of seeds per siliquae showed positive and significant correlation with number of secondary branches per plant number of siliquae per plant showed positive and significant correlation with number of primary branches per plant while it showed significant and negative correlation with days to 50% flowering and days to 100% flowering. Days to 100% flowering showed positive and significant correlation with days to 50% flowering. Erucic acid was positively and significantly correlated with oleic acid while it showed negative and significant correlation with palmitic acid and linoleic acid. Eicosenoic acid showed positive correlation with oleic acid while stearic acid was negatively correlated with Palmitic acid. For some of the characters gca variances were found to be significant while sea variance showcd significance for some characters. The higher magnitude of gca than sea exhibited involvement of additive genetic variance for some traits and rest traits showed higher magnitude of sea, where non- additive gene action was involved. The reciprocal variances were also found to be significant for some traits and were even more pronounced on both gca and sea for some traits. PYS-2009-1 was found to be best general combiner followed by B-9 and PYS-2005. Majority of crosses showed a moderate to high range of heterosis for all the traits. Economic heterosis was found maximum for number of siliquae per plant (205-276%) and minimum for day to maturity (4.00-5.00%) YSBNC-1xYSCN-14(days to 50% flowering, days to 100% flowering, oleic acid), PYS-9808-1xPYS-2009-1(days to maturity, number of secondary branches per plant) and YSBNC-1 xB-9 (number of primary branches per plant and number of siliquae per plant) were the best heterotic crosses.
