ThesisItem Open Access Evaluation of advanced wheat lines for stripe rust resistance and grain quality(CCSHAU, Hisar, 2019-08) Bhawna; Bhawna; Yadav, Neelam R.; Yadav, Neelam R.Biofortification of staple foods like wheat without any yield penalty is of utmost importance. Advanced lines introgressed with Gpc-B1 allele were used in the study. The Gpc-B1 allele co-segregated with Yr36 yellow rust resistance gene in all the advanced lines. All WH711-derived advanced wheat lines confirmed for the Yr36/Gpc-B1 allele. Seven advanced lines (WL-8-1, WL-8-2, WL-8-3, WL-8-5, WL-8-6, WL-8-7, WL-8-8) were confirmed for Yr18 while six advanced lines (WL-8-1, WL-8-2, WL-8- 6, WL-8-7, WL-8-8, WL-8-9) were positive for Yr17 gene. All five PBW343-derived advanced lines confirmed for the Yr36/Gpc-B1 allele presence. Three advanced lines (PL-8-2, PL-8-3, PL-8-4) displayed the presence of the Yr18 gene. Two advanced lines (Pl-8-3, PL-8-5) confirmed presence of the Yr17 gene. All the advanced wheat lines derived from WH711 as well as from PBW343 displayed very high levels of resistance against yellow rust and better agronomic characteristics than the parents. Positive correlation was observed in yield and yield related traits. The hectoliter weights of PBW343-derived lines indicated their superiority in terms of good flour recovery than PBW343 and comparable to the checks. WH711- and PBW343- derived advanced wheat lines show better gluten quality and high quantity in sedimentation test. Gpc-B1 allele introgression provided high GPC in WH711 derived advanced wheat lines. Iron and zinc contents of both WH711-derived and PBW343-derived advanced wheat lines were at par when compared to either parent and checks, indicating successful bio fortification of both micronutrients. Two of the WH711-derived lines are being further tested in IPPSN/station trials.ThesisItem Open Access Studies on effect of post-harvest treatments and storage conditions to enhance shelf life of ber (Ziziphus mauritiana L.)(CCSHAU,HiSAR, 2020) Bhawna; Goyal, R.KThe present experiment entitled “Studies on effect of post-harvest treatments and storage conditions to enhance shelf life of ber (Ziziphus mauritiana L.)” was conducted in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2019-20. Fruits were treated with post-harvest treatments viz. lemongrass oil 0.1%, til oil 2%, Aloe vera 100%, salicylic acid 1mM, calcium chloride 2%, citric acid 0.5%, sodium nitroprusside 1mM and control. Fruits were stored at room temperature as well as cold storage conditions. The minimum loss in weight, decay loss and maximum colour, specific gravity, sugars and total chlorophyll content were recorded in fruits treated with Aloe vera 100%. The maximum fruit firmness was observed in fruits treated with Aloe vera 100% and salicylic acid 1mM whereas, maximum ascorbic acid was observed in calcium chloride 2%, salicylic acid 1mM and Aloe vera 100% treated fruits at room temperature storage. The minimum loss in weight, decay loss and maximum fruit firmness, specific gravity, organoleptic quality and total chlorophyll content were maintained by fruits treated with Aloe vera 100% under cold storage conditions. The maximum ascorbic acid content, total soluble solids and sugars were observed in fruits treated with calcium chloride 2% under cold storage conditions. The maximum free radical scavenging activity was observed in fruits treated with salicylic acid 1mM under both room and cold storage conditions. Loss in weight and decay loss increased with prolongation of storage period whereas, ascorbic acid content, acidity, fruit firmness and specific gravity decreased with the advancement of storage period under both storage conditions.ThesisItem Open Access Chemical parameter of plantago ovata forsk and asparagus racemosus willd seeds(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 2003) Bhawna; Khabiruddin, M
