    Genetic analysis of natural variability in Sesame (Sesamum indicum L.)
    (CCSHAU, Hisar, 2023-07-24) Rohit; Subhash Chander
    The study was carried out to investigate genetic variability and to assess genetic diversity in 50 sesame genotypes. During kharif 2022, the experiment was conducted in Randomized Block Design with three replications at the experimental area of Oilseeds Section, Department of Genetics and plant breeding, CCS Haryana Agricultural University, Hisar. Each genotype was sown in single row of 3-meter length with spacing of 30 x 15 cm and evaluated for twelve quantitative characters. Analysis of variance showed highly significant differences in the material for all the studied characters. Highest genotypic and phenotypic coefficient of variation was found for seed yield/plant followed by secondary branches/plant, number of capsules/plant, number of primary branches/plant and number of seeds/capsule. High heritability coupled with genetic advance was observed for number of primary and secondary branches/plant, number of capsules/plant, number of seeds/capsule and seed yield/plant. The seed yield/plant showed a significant positive correlation with plant height, number of primary branches/plant, number of capsules/plant, number of seeds/capsule, capsule length, capsule width and 1000-seed weight, and negative correlation with days to 50% flowering, days to maturity and oil content. Path analysis revealed that primary branches/plant and capsule length had positive effects on seed yield/plant while negative effect was shown by days to 50% flowering and oil content. The D2 analysis classified all the genotypes into five clusters. Cluster II had the highest number of genotypes followed by cluster III and cluster I. The highest inter-cluster distance was observed between clusters I and II. Maximum contribution towards genetic divergence was due to secondary branches/plant (20.94%) followed by primary branches/plant (19.51%) and seed yield/plant (17.59). In conclusion, the genotypes NIC-17274-C and NIC-7897 (Cluster I), NIC-8394 (Cluster III) and HT-2 (Cluster IV) should be used in hybridization programme for improvement of seed yield and oil content in sesame.

    Impact of seed treatments on quality of different aged seeds of oat (Avena sativa L.)
    (CCSHAU, Hisar, 2023-07-20) Rohit; V.S. Mor
    The present studies entitled “Impact of seed treatments on quality of different aged seeds of oat (Avena sativa L.)” were carried out at Laboratory and field of Department of seed science and technology, CCS HAU, Hisar. The seed treated with Azotobacter+Phosphate solubilizing bacteria enhanced the seed quality in terms of all parameters of fresh, one year old and two year old seed lot of oat and Chlorpyrifos and their combinations showed negative effect on seed quality. Among the three years seed lots, highest performance were observed in freshly harvested seeds for various seed quality parameters i.e radicle emergence (88.69%), speed of germination (54.33), standard germination (93.46%), seedling length (40.94 cm), seedling dry weight (12.37mg), vigour index-I (3,829.30), vigour index-II (1,156.93), field emergence index (9.75), seedling establishment (69.96%) and plant height (28.75cm) at 30 days whereas, the maximum enhancement in standard germination and vigour indices was observed in one year seed lot and the minimum was observed in fresh seed lot. The correlation study shows that the field emergence of oat had positive and significant correlation with germination percentage, seedling length and seedling dry weight. The seedling establishment was also found significantly correlated with vigour index-I, vigour index- II, field emergence and speed of germination. Similarly, field emergence index was significantly correlated with vigour index-I, seedling length, vigour index- II, seedling dry weight, germination percentage and non-significant with speed of germination. The seedling establishment of oat in the field was found to have significant positive correlation with most of the seed quality parameters such as germination percentage, seedling length and seedling dry weight but negative correlation with radicle emergence.

    Study on professional aspirations of agriculture graduates
    (CCSHAU, 2018) Rohit; Mehta, S.K.
    The present study was carried out at CCS Haryana Agricultural University, Hisar during 2017-18 to analyze the aspirations of agriculture graduates. The data were collected from all the students of final year during the academic year 2017-18, having a total sample of 160 respondents using pre-tested interview schedule through personal interview method. The standardized scales with partial modifications and appropriate schedule were developed and used in the study. The specific objectives of the present study were (1) To study personal and socio-economic characteristics of the agriculture graduates (2) To know the aspirations of the agriculture graduates (3) To find out the correlation between personal attributes of the agriculture graduates and their aspirations. The 11 important independent variables namely, caste, gender, marital status, stream of education at 10+2 level, academic performance, land holding, parental occupation, annual income, social participation, mass media exposure and allied activities and aspirations comprised educational aspirations, job aspirations, social aspirations, economic aspirations and professional aspirations which were the dependent variables. It was observed that majority (74.30%) of the students were male sex and belonged to the non-reserved caste (54.90%) and came from nuclear family (86.30%). Almost all the students were unmarried and only one student found was found married. Majority (61.10%) of the students had medical as stream of education at 10+2 level, more than half of the respondents (56.60%) obtained between 70.1- 80 per cent and 35.40 per cent of the students had small size of land holding. Whereas majority (36.60%) of the respondents‟ parental occupation was government service and 44.60 per cent of them had total annual income between (Rs. 5,70,001 to 8,35,000). Almost all the students (98.00%) were found no member of any organization, most of the respondents gave preference to Internet as their prime mass media exposure tool followed by books and journals. The findings also revealed that majority (63.40%) of the agriculture graduates had medium level of participation in allied activities. Majority (68.50%) of the students had medium level of aspirations and 76.40 per cent of them aspired to pursue higher education in agriculture and to work in educational and research institutions (28.60%). However, more than half (55.40%) of the respondents aspired to earn Rs. 50,000 to 60,000 monthly, while nearly half (48.00%) of the students aspired to get social recognition and maximum number (42.30%) of the students aspired to become a renowned scientist. It is observed from the study that the caste, subject at 10+2 level, family type, land holding and social participation could not show any significant relationship with the aspirations of the agriculture graduates. The variables i.e. gender and marital status were negatively associated with the aspirations of the agriculture graduates. Allied activities were found significantly associated with the aspirations of the agriculture graduates. Whereas variables such as academic performance, annual income and mass media exposure of the students were positively and highly significantly related with the aspirations of the agriculture graduates.
