    Genome wide association mapping for stem water soluble carbohydrates in bread wheat (Triticum aestivum L.) under terminal water stress
    (CCSHAU, Hisar, 2020-11-26) Gaur, Arpit; Jindal, Yogesh
    Genomic assisted breeding is one way to improve drought stress tolerance in wheat. To uncover the genomic regions for grain yield, its attributing traits, water soluble carbohydrates (WSCs) and its components mainly fructans, a comprehensive multidisciplinary study was conducted with a diverse set of 302 bread wheat genotypes. All the genotypes were evaluated under complete irrigation, rainfed and complete water stressed condition for two consecutive crop seasons at three locations (Hisar, Karnal and Baramati). The study indicated significant effect of different water regimes and locations on the expression of traits and as much as 80% of yield reduction was reported under DT. Seven promising drought tolerant verities were identified on the basis of drought susceptibility index. In this study, correlation between yield and studied traits largely varied with environmental and water conditions. However, shorter plant height, longer grain filling duration, days to heading, thousand kernel weight (35-40 g) is the most favorable trait combination for obtaining high grain yield under studied conditions. Positive correlation of WSCs with grain yield was reported only for drought tolerant genotypes. High values of all the genetic components were reported for all the traits within environments, however in pooled over management these values ranged between low to moderate for most of the studied traits due to genotype x environment. Traits like plant height, peduncle length, spikelet per spike and thousand kernel weight were least influenced with genotype x environment interaction thus found suitable for selection of grain yield. Substantial genetic diversity was reported in the studied material which was attributed by each of the studied trait equally. With 35K Axiom array and applying compressed mixed linear model, 431 stable SNPs were identified for 20 studied traits in 1288986.92 cM genomic region of bread wheat. These SNPs explained ca. 30-53% of phenotypic variations. Of 431 stable SNPs 77 were showing pleiotropy for various traits. Five SNPs (AX-94583229, AX-94879209, AX-94759517, AX-94887053 and AX-94964616) for fructans and total non-structural carbohydrates, three (AX-94508292, AX-95257620 and AX-94456473) for days to heading and one (AX-94412521) for plant height were most significant. In functional analysis of significant SNPs, 249 genes were identified which were mainly involved in carbohydrate metabolism and repair mechanism. Only few were reported with direct involvement in stress responses. In an in silco study 104 genes (TaFruc) transcribing into stable protein associated with fructans metabolism were identified. All of these were involved in either hydrolase or transferase activities of glycosyl groups of soluble sugars. These genes were found expressive under different stress conditions, mainly water stress. To facilitate the future breeding programs a total of 189 SSR molecular markers and 60 micro RNAs have been predicted successfully for TaFruc genes.

    Effect of biomordants on dyeability of cotton fabric with natural dye
    (CCS HAU, Hisar, 2020-07) Neeta; Arya, Nisha
    Increasing concern about environmental pollution in all sphere of life has raised grave concern and heated debates around the world about the concept of ecology and environment. In the present time, commercially viable alternative methods for preparing and finishing cotton substrates based on the use of biomordants have emerged. Keeping in view the current scenario of environmental consciousness, the present study has been planned to assess the effect of biomordant on dyeing efficacy of cotton with natural dye substituting metal based mordant and salts. Standardization of biomordanting process for two biomordants i.e. harad and heena was done on the basis of dye absorption, colour strength and wash fastness rating for different concentrations and treatment conditions. The desized and scoured fabric were pre-treated with selected two biomordants and dyed with selected natural dye. Scanning Electron Microscopic (SEM) analysis of biomordanted fabric samples. SEM analysis demonstrated plain surface of biomordant treated sample. The colour coordinates, colour strength and colour fastness of the biomordant treated dyed samples were assessed. Various mechanical, performance and functional properties of the biomordant treated dyed fabric were also tested. Comparative analysis was also done between scoured fabric treated with biomordants and dyed with natural dye. The parameter optimized for biomordanting process of scoured fabric were pre mordanting stage with 5 and 10 per cent concentration, 1:30 M: L Ratio, 6 and 4 pH, 60° and 80°C treatment temperature and 60 and 45 minutes treatment time for heena and harad, respectively. Both the biomordant treated dyed samples exhibited good (4) to very good (4/5) colour fastness properties. The results revealed that among both the biomordants treated dyed fabrics, heena treated dyed fabric showed maximum increase in bending length (2.39 cm) and heena treated dyed sample showed highest increase in elongation (29.68%), crease recovery angle (113 degree), moisture regain (10 %) and wickability (3.86cm). The heena treated and Babool bark dyed fabric showed the highest UPF value (56.89) indicating excellent protection category while in harad treated dyed fabric UPF value was (48.76). The biomordants treated dyed fabrics showed bacterial resistance against E. coli (93.35%) and S. aureus (88.07%). Thus, it is concluded that biomordants treatment enhanced the dyeing efficacy of the cotton fabric with better colour fastness properties. The biomordant treatment and Babool bark dye improved the mechanical and performance properties of cotton fabric with very good to excellent protection from UV radiation and bacterial attack. Hence, the biomordants are suitable replacement materials for cotton fabric in textile wet processing due to their positive response towards environment and no harmful effect on fabric properties.

    (CCSHAU, Hisar, 2020-07) Swati Rani; Upendra Kumar
    Strawberry (Fragaria × ananassa Duch.) is the most important fruit worldwide. Micropropagation is mainly for the clonal multiplication.Strawberry cvs. Grenada and Petaluma were micropropagated for rapid shoot and root multiplication. Meristematic part and leaf primordia is source of explants. Foe the sterilization process, the explants were dipped in two to three drops of Tween 20 per 100 ml for 10 minutes with distilled water, 0.5% Bavisitin & Streptocycline for 30 mintues with antimicrobial supplement and 0.1% HgCL2 for 2 minutes gave the maximum aseptic cultures. After the surface sterilization of meristemetic part of plants 3-5 mm long was used as a explant. Multiplication stage results indicate that highest auxiliary buds were observed when MS medium supplemented with 1 mg/l and 1.5 mg/l BAP in Petaluma and Grenada. At rooting stage, it was clear visually that MS medium supplemented with 0.5 mg/l of BAP with 1.5 mg/l of IBA in both the cultivars gave the best results of enhanced number roots with higher length and number shoots with higher length per explants. The best result for root multiplication indicating the use of IBA with ( 1.0, 1.5 mg/l) concentration as compared to other treatments.The highest response for the shoot multiplication was obtained with MS containing 1.5 mg/l and 1.0 mg/l BAP respectively. The present research is very useful in commercializing the new cultivars of strawberry into north Indian conditions which gives higher yield of fruits.

    In silico identification and physical mapping of gene(s) responsible for β-glucan in Bread Wheat (Triticum aestivum. L)
    (CCSHAU, Hisar, 2020-07) Dhamija, Aryan; Upendra Kumar
    Dietary fibers from plant cell wall are an essential component of healthy foods. Higher intake of dietary fiber reduces the risk of diet related chronic disease like type 2 diabetes, obesity and also improves gastrointestinal health. In human diets, cereal fiber is the largest contributor to total dietary fiber consumption. The soluble dietary fiber (1-3) (1-4) mixed linked β-D-glucan from cereal grains is a valuable component of a healthy diet. In the present investigation, the gene responsible for β-glucan in hexploid wheat was identified using both in silico and molecular methods.The in silico analysis confirmed that CslF6 gene in wheat was located on the chromosome 7A. Sequence similarity search was conducted between HvCslF6 and wheat survey sequences displayed a similarity of 96% with chromosome 7A. The structure of this gene had 3 exons and codes for a protein of 945 amino acids. Homology modeling of putative CslF6 protein was described as Probable cellulose synthase A catalytic subunit 8.Different cytogenetic stocks of Chinese spring revealed that CslF6 gene was located on centromeric region of 7AL (FL=0.29). Identified CslF6 in wheat can be utilized to make β-glucan efficient wheat and can be used in biofortification program.

    Interaction of Sesbania rhizobia with different species of Sesbania and kharif legumes
    (CCSHAU, Hisar, 2020-11) Jeniffer Christeena Masih; Gera, Rajesh
    Sesbania is an important wild legume as it can grow in wide range of soils like alkaline, waterlogged and acidic soils. It has high nitrogen fixation properties due to its association with rhizobia in both root and stem nodules. Rhizobia from wild legume like Sesbania may function as excellent plant growth promoting bacteria.Therefore, the present research was carried out to study the interaction of Sesbania rhizobia with different species of Sesbania and kharif legumes. A total of 25 Sesbania rhizobial isolates, which includes five isolates each from Sesbania aculeata, S. sesban, S. grandiflora, S. rostrata (root nodulating and stem nodulating), were included in the present investigation. Out of which 21 rhizobial isolates were obtained from departmental culture collection and 4 rhizobial isolates were isolated from soils collected from different locations of India using trap plant method. All the rhizobial isolates were able to produce IAA and ammonia, however, 92, 48 and 48 % rhizobia had the ability for phosphate solubilization, bacteriocin and siderophore production, whereas, 60% of rhizobia were able to utilize ACC. All the rhizobial isolates showed the presence of nifH and nodC genes. Five rhizobial isolates namely SSKr(ii), SGMg, SAUd(i), SRKr(iv)/r and SRTn/s from each Sesbania species were selected on the basis of different plant growth promoting traits, nodulation efficiency and amplification of nodC and nifH gene, to study their effect on different Sesbania species, mungbean and pigeonpea under sterilized conditions. The rhizobial isolates; SRKr(iv)/r (root nodulation) and SRTn/s (stem nodulation) were found to be most efficient isolates on the basis of nodule number and fresh nodule weight in cross nodulation within Sesbania species and other legumes. These isolates were also tagged with gfp gene to study their colonization on different parts of Sesbania rostrata. Recovery of GFP marked strains from root, root nodules, stem and stem nodules was 95 to100%. However, recovery of gfp marked strains from the surface of root and root nodules varied from 92 to100% while on the surface of stem and stem nodules, it ranged between 25 to 33%. Rhizobial isolate; SRKr(iv)/r showed good nodulation efficiency in all four Sesbania species and pigeonpea as compared to other rhizobial isolates under unsterilized conditions. Nodule occupancy of GFP marked strains; SRKr(iv)/rGFP+ and SRTn/sGFP+ under unsterilized condition was found to be 33-54 and 92% in case of root and stem nodules, respectively of Sesbania rostrata.

    Biochemical changes in genetic and induced systemic resistance due to infection of Albugo candida (Pers. ex. Lev) in Indian mustard
    (CCSHAU, Hisar, 2020-03) Annu; Rathi, A. S
    White rust disease incited by Albugo candida is an important disease of Indian mustard (Brassica juncea) in India particularly in northern and North eastern states. Keeping in view the enormous losses caused by the pathogen, the present investigation has been devised on biochemical changes due to infection of Albugo candida in different Indian mustard genotypes, induction of systemic resistance by non conventional chemicals, identification of slow white rusting genotypes and role of micronutrients in defence against white rust under laboratory, screen house and field conditions at Chaudhary Charan Singh Haryana Agricultural University, Hisar. The results of biochemical analysis revealed that total phenolic content, PO, PPO, PAL and chitinase activity were found higher in healthy leaves of resistant genotypes (BIOYSR, EC399299) as compared to moderately resistant genotypes (EC399301, DRMRIJ-31) and susceptible genotypes (RH 30, RH 8812) at 35-40 DAS. There was steep increase in all the biochemical constituents at the time of disease initiation ie. at 45-50 DAS. However, increase was more in inoculated environment as compared to uninoculated environment. At maximum disease severity i.e.70-75 DAS, there was decline in all the biochemical constituents in all genotypes under both the environments. Decrease was more in susceptible genotypes indicating the exhaustion of these biochemical constituents which otherwise consider necessary to trigger genetic resistance through pathways. Efficacy of six non conventional chemicals were tested with different concentrations for induction of resistance against white rust. None of the non conventional chemical completely controlled the white rust disease even at higher concentration of 100 μg/ml. However, a maximum control was also recorded by BTH at 100 μg/ml concentration after six weeks of challenge inoculation by the pathogen followed by SA in both the variety (RH 30 and RH 0749) under screen house conditions. BTH has shown maximum induction of phenolic content, PO, PPO, PAL and chitinase activity at three days after inoculation (DAI) in both the varieties at 100 μg/ml concentration followed by SA. However, MgSO4 has shown minimum induction of these activities at three DAI in both the varieties.Out of 22 Indian mustard genotypes screened for identification of slow white rusting component, 9 genotypes exhibited longer incubation and latent periods, minimum number of pustules per leaf, minimum size of pustule, minimum sporulation, minimum disease severity and minimum AUDPC indicating slow white rusting behaviour. Among the different treatments of mcronutrients alone and in combinations, soil application of Gypsum + Borax + CuSO4 + Na2MoO4 at 30 DAS as basal dose recorded minimum white rust severity of 31.1% and staghead incidence of 4.44% and highest seed yield of 2228.55 kg ha-1 as compared to the 45.83% white rust severity and 6.09% staghead incidence and seed yield of 1779.79 kg ha-1 in control. Maximum number of primary branches per plant (5.83), secondary branches per plant (12.33), main shoot length (90.93 cm), siliquae on main shoot (62.60) and seeds per siliquae (12.53) were also observed with above treatment. Plant height, siliqua length, oil content and 1000 seed weight did not vary significantly among all the treatments.

    Molecular approaches for detection and forecasting of wheat yellow rust
    (CCSHAU, Hisar, 2020-03) Rizwana Rehsawla; Yadav, Neelam R.
    Yellow or stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a devastating airborne disease that affects bread wheat in the major wheat growing regions of India. The understanding of the origin, evolution, pathogenicity, avirulence/virulence behaviour of Pst is very important for the development of more effective management strategies to combat the disease spread. To understand inter and intraspecific phylogenetic relationship among Indian Pst pathotypes, multigene sequence analysis was done. Molecular marker study along with sequencing technology was used to collect information, which was more effective than virulence characterization. The molecular diversity analysis among 13 different Pst pathotypes showed two major cluster formations at similarity coefficient of 0.78. Sometimes, all three wheat rust or two rusts in combination occur simultaneously in the field. Under such conditions identification and differentiation of the yellow rust is needed for precise identification and high throughput DNA based detection protocols. To address this problem PCR based markers were developed which can specifically detect and differentiate Pst from two other rust species of Puccinia and other wheat pathogens. DNA-based methods such as conventional PCR have revolutionized plant disease detection; they are not very reliable at asymptomatic stage. Therefore, a simple and reproducible LAMP assay was developed which could detect the pathogen at an early stage i.e. 3rd day of post infection without any visible sign of pathogen attack on the leaf sample using LAMP primers available in public domain. Four novel sets of LAMP primers from ketopantotate reductase gene were also designed for Pst detection which worked successfully. Biosensing by electrochemical and SPR for the detection of yellow rust was also undertaken. Electrochemical based sensing was done using different sequences of Pst specific genes as probes. Linear response over wide DNA concentration range from 10 pg/μl to 115ng/μl was obtained with a high sensitivity, accuracy and reproducibility. The lowest detection limit was observed for microRNA like RNA 1 gene i.e. 10 pg/μl. Electrochemical DNA based biosensing was developed to distinguish between the yellow rust susceptible and resistant wheat genotypes using TaATG8j gene sequence. Linear response over wide DNA concentration range from 1 ng/μl to 50 ng/μl was obtained with detection limit of 4 pg/μl. The SPR biosensor demonstrated high specificity and long shelf life thus promising its application in Pst diagnosis. The developed biosensor exhibited a high sensitivity (0.18°/ (ng/μl)), good linearity, low detection limit (1 ng/μl) and high specificity over a wide concentration range of DNA (1–150 ng/μl).

    To evaluate the compatibility and efficacy of post-emergence herbicidal combinations tank mixed with zinc and iron sulphate against weeds in wheat (Triticum aestivum L.)
    (CCSHAU, Hisar, 2020-07) Jitender; Amarjeet
    Wheat (Triticum aestivum L.) is one of the major cereal food crops of the world. Weeds are one of major biotic factors affecting wheat production significantly and now a days, micronutrients deficiency is also being observed in mostly wheat growing areas. Very less information is available regarding compatibility of herbicides with micronutrients. Field experiment was conducted at RRS, Bawal during Rabiseason of 2018-19 to evaluate the compatibility of post-emergence herbicidal combinations with Zn or/and Fe. Experiment consisted of 18 treatments replicated thrice, was laid outin Randomized Block Design. Four herbicidal combinations viz. clodinafop + metsulfuron@ 60 g/ha, sulfosulfuron + metsulfuron @ 32g/ha, mesosulfuron + iodosulfuron @ 14.4 g/ha, pinoxaden + carfentrazone @ (50 + 20g/ha) were evaluated for compatibility with Zn {ZnSO4(0.5%) + urea (2.5%)}, Fe {FeSO4 (0.5%)} and with both Zn as well as Fe {ZnSO4 (0.5 %) + urea (2.5 %) + FeSO4 (0.5 %)}. The results of experiment revealed that all four herbicidal combinations studied were found compatible with Zn and Fe as well. Tank mixing of herbicidal combinations with Zn or Fe exhibited a bit improvement in growth and yield of wheat. While, tank mixing of both Zn and Fe with herbicidal combinations showed significant increase in growth parameters and subsequently grain as well as biological yield of wheat as compared to sole application of respective herbicidal combination. Among all the treatments, application of mesosulfuron + iodosulfuron (14.4 g/ha) + ZnSO4 (0.5%) + urea (2.5%) + FeSO4 (0.5%) was observed as most productive with highest grain yield (5655 kg/ha) and profitable with highest net returns (Rs. 60973/ha) and B:C (1.88).Satisfactory weed control was observed with all the treatments of herbicidal combinations Tank mixing of Zn and Fe improved the efficacy of herbicidal combinations by improving competitive ability of wheat through better growth resulting into higher weed control efficiency. The uncontrolled weeds caused 34 per cent loss in grain yield.
