    Analysis of diversity for micronutrient content and DNA fingerprinting in Greengram [Vigna radiata (L.) Wilczek]
    (2009) Jyoti; Yadav, Neelam
    Vigna radiata (L.) Wilczek, commonly called mungbean or greengram is the third most important pulse crop of India occupying nearly 3 million hectare. Mungbean provides inexpensive, low flatulence and easily digestible protein available in several edible forms that complements staple rice diet in Asia. India is the primary greengram producer and contributes about 75% of world production. Iron and Zinc are important micronutrients for human health whose deficiency causes anemia and malfunctioning of immune system. Commercial cultivars contain low levels of iron and zinc and it is important to assess genetic -IIvariability in available germplasm for improving micronutrient content in commercial cultivars. The present study was undertaken to study RAPD polymorphism among 16 mungbean genotypes using 33 decamer primers in PCR reaction. A total of 148 amplified bands were produced out of which 142 were polymorphic and 6 were monomorphic. For the genotypes studied, upto bands were produced with an average of 6.16 bands per primer. The size of amplified bands ranged from 150-3000 bp. Some unique bands were also produced, which could be used to distinguish these genotypes. The similarity coefficients between different genotypes ranged from 0.40-0.89 with an average similarity value of 0.65. At an arbitrary cut-off at 60 per cent similarity level on a dendrogram, the mungbean accessions were categorized into two major clusters. Satya and Asha were found to genetically similar. ML776 showed high iron and zinc content while Satya was poor in iron as well as zinc content. OPB7 primer showed 900 bp amplified product in ML776 that was found absent in Satya. These two genotypes can be used in developing population for linkage mapping. The results indicated that RAPD markers were efficient for identification of Vigna radiata genotypes and for determination of the genetic relationships among them.

    Protective clothing for textile industrial workers
    (CCSHAU, 2010) Jyoti; Pruthi, Neelam
    Textile industry is known as backbone of Indian economy also provide several threats to its workers, while performing various activities. All the health problems can be solved by variety of method and use of appropriate protective clothing is one of effective method to prevent the workers from being exposed to health problem. To achieve the objectives of he study, it was inducted in two phases. In phase 1 to develop protective clothing for workers of textile industry and to assess their suitability and acceptability Delhi cloth Mill of Hisar and Bhiwani textile mill of Bhiwani were selected. Hundred respondents from different section of textile industry were selected to gather information regarding health and clothing related problems. In second phase protective clothing were designed. The sketched designs were evaluated by Judges and two designs of each article were selected for construction. Protective clothing/accessories selected were: Beak shape mask, cap mask, hood masks, scarf mask, shirt (Male) coverall for male, coverall for female, waist level apron, foot cover and foot cover with pajama. The selected articles were stitched and each article was given to five respondents for three trials. After three trial, suitability and acceptability was assessed. The result highlighted that scarf mask, hood mask for female and cap mask, hood mask for male was found suitable as these gave protection against fiber dust stick on head, neck and inhalation of fiber dust particles. But acceptability of scarf mask for female and cap mask for male was highly acceptable as compared to hood mask because of excessive heat in the industry and with the use of hood mask identification of the workers is difficult. Coverall with Chinese collar, pockets and elastic at wrist level in sleeves was found to be highly suitable and acceptable as compared to waist level apron, while male shirt with Chinese collar, elasticized cuff, pockets in front were found highly suitable and better than coverall. In case of pajama with foot cover and knee length foot cover, knee length foot cover was fond to be highly suitable and acceptable as compared to pajama with foot cover.

    Studies on the effect of growing media on seed germination and seedling growth of papaya (Carica papaya L.)
    (CCSHAU, 2016) Jyoti; Beniwal, B.S.
    The present study entitled “Studies on effect of growing media on seed germination and seedling growth of papaya (Carica papaya L.)” was carried out at experimental orchard of Department of Horticulture, CCS Haryana Agricultural University, Hisar during the rainy season of 2015. Different growing media combinations comprising of sand, garden soil, sand + garden soil (1:1), sand + vermicompost (2:1), sand + FYM (1:1), garden soil + vermicompost (2:1), garden soil + FYM (1:1) with and without cocopeat were prepared and filled in polyethylene bags. The experiment comprising of fourteen treatments was carried out in completely randomized (factorial) with three replications under two growing conditions viz. polyhouse and open conditions during rainy season. Five representative plants were randomly selected from each replication to record data on the various parameters. It was observed that garden soil + vermicompost (2:1) + 2 cm top layer of cocopeat gave minimum days for germination, highest rate of emergence, germination, germination index and maximum number of leaves, stem girth, seedling height, root length, root fresh weight, shoot fresh weight and plant fresh weight under open field condition. Highest survival and minimum days to transplanting were also observed in soil + vermicompost (2:1) + 2 cm top layer of cocopeat under open field conditions. The interaction between growing media and growing conditions was found nonsignificant.

    Development and Nutritional Evaluation of Value Added Products from Shiitake (Lentinus edodus) Mushroom
    (CCSHAU, 2015) Jyoti; Sindhu, Sangeeta C.
    The present study delineates information pertaining to the nutritional evalution of Shiitake mushroom (Lentinus edodes) and development, nutritional evaluation and shelf life studies of products. Moisture content in Lentinus edodes was found to be 90.31 per cent. Crude protein, crude fat, ash and crude fibre content respectively were 20.90, 0.95, 7.20 and 8.06 per cent. Minerals analysis revealed total iron, zinc, phosphorus and calcium content in mushroom to be 5.01, 10.09, 960.66 and 41.41 mg/100g respectively. HCl extractability for iron, zinc, phosphorus and calcium were 94.78, 70.89, 14.89 and 53.74 per cent respectively.The total carbohydrate, total soluble sugar, reducing sugar, non- reducing sugar and starch in L.edodes were 62.89, 4.72, 0.48, 4.24 and 5.84 per cent respectively.The total dietary fibre, soluble and insoluble fibre content were 32.33, 1.93 and 30.29 g/100g respectively. L.edodes mushroom had a polyphenol content of 201.34 mg/100g and in vitro protein digestibility 80.53 per cent. Mushroom powders were prepared using different treatments.The mushrooms were either blanched or kept unblanched. These were further subjected to different chemical treatments including KMS or Citric acid/H2O2 before drying (solar/oven).The yield of powder obtained after drying ranged from 1.89 to 6.90 per cent in different treated and untreated dried mushroom powders. Oven drying after KMS treatment of unblanched mushroom resulted in highest yield of mushroom powder while solar drying after treatment with H2O2 of unblanched mushroom yielded minimum powder. All treatments were effective in producing organoleptically acceptable powders. The overall acceptability score of dried mushroom powders ranged 2.60 to 5.18 on six point hedonic scale. In our study, various treatments reduced the crude protein content by upto 13.38 per cent; maximum reduction was brought about in blanched H2O2 treated solar dried powder. The crude protein content in dried powders ranged between 18.12 to 20.92 per cent. All blanched mushroom powders had significantly (P≤0.05) lower crude protein content as compared to their unblanched counter parts irrespective of other treatments involved. All the treatments significantly (P≤0.05) improved the in vitro protein digestibility of mushroom powders. The in vitro protein digestibility was highest (85.94%) for blanched KMS treated oven dried mushroom and lowest(82.48%) for unblanched citric acid treated oven dried powder as well as unblanched H2O2 treatment solar dried powder. Blanched mushroom powders had significantly (P≤0.05) higher in vitro protein digestibility as compared to unblanched counter parts irrespective of other treatments involved. Antimicrobial activity of treated and untreated powder was studied against B.subtilis, E.coli, S.typhi and S. aureus in aqueous and alcoholic extracts. No significant results were achived with alcoholic extracts. Aqueous extracts exhibited inhibition zones against all test microorganisms. Blanched KMS treated solar dried Shiitake powder provided maximum zone of inhibition against S. aureus (28mm). On the basis of organoleptic acceptability of different dried powders citric acid solar dried powder were used for the development of various mushroom products i.e. Mushroom pickle, Mushroom chutney, Instant soup mix, Ready to use mushroom curry and biscuits. All the developed products were acceptable to the panel of judges. The storable products were stored and evaluated for a period of 30 days at room temperature. Mushroom curry could be stored only upto 15 days with no deterioration in any parameter. All other products could be successfully stored up to 30 days.

    Phenotypic and genotypic diversity in pearl millet [Pennisetum glaucum (L.) R. Br.] germplasm lines
    (CCSHAU, 2015) Jyoti; Dev Vart
    Phenotypic and genotypic diversity in pearl millet [Pennisetum glaucum (L.) R. Br.] was studied in a set of 48 maintainer lines using 30 morpho-agronomic traits (16 qualitative and 14 quantitative) and 22 SSR markers. Significant mean sum of squares indicated sufficient variation in the lines. Leaf sheath length, number of productive tillers/plant, plant height, 1000 grain weight, grain yield/plant had high GCV, PCV, heritability and genetic advance as % of mean. Correlation coefficient analysis revealed that days to 50% flowering, spike length, number of productive tillers per plant, 1000 grain weight, dry and green fodder yield were significantly and positively correlated with grain yield per plant. Path coefficient analysis revealed that days to 50% flowering, spike length, number of productive tillers/plant had high significant direct contribution towards grain yield/plant. First five principal components explained 81.02% of accumulated variability. D 2 analysis led to formation of seven clusters. The highest inter-cluster distance was found between clusters 1 and 7. Based on Principal Component and factor analysis, genotypes HMS 43B, HMS 45B, HMS 60B, ICMB 97111, Tift 23 D 2B etc. showed high grain yield and high number of productive tillers/plant and plant height. Genotyping of maintainer lines with 22 polymorphic SSR markers lead to formation of 8 groups. Three out of 22 polymorphic primers showed PIC value of more than 0.70. Phenotypic and genotypic clustering showed that some genotypes grouped together in the two data sets.
