Combining Ability Analysis of Quality Protein Maize Inbred lines
The present study was aimed to assess the general combining ability of parents and specific combining ability of their crosses for yield and quality traits. Nine inbred lines were crossed with three testers using line × tester mating design. Nine lines, three testers and 27 F1s were evaluated along with two checks in this study for grain yield per plant, grain protein content, tryptophan content and lysine content during Rabi 2021-22 and Spring 2022. Total 41 genotypes (27 crosses, 9 lines, 3 testers and 2 checks) were evaluated in Randomized Block Design with three replications at experimental farm of BAC, Sabour. Based on general combining ability analysis parents L4, L6, L9 were found as good general combiner for grain yield & quality traits in rabi season. L1, L2 and L3 were accompanied with significant GCA in desired direction for tryptophan and lysine content in spring season. Among the crosses L2 × T1, L7× T3 and L3× T1, L9 × T3 exhibited highly significant and desirable SCA effects for grain yield per plant in rabi and spring season respectively. L3× T3 possessed highly significant SCA effects for protein, tryptophan and lysine content in spring season. Therefore, these crosses can be utilized for developing high yielding good quality hybrid varieties in maize. There was preponderance of non-additive gene action in the inheritance of all the traits.
In silico Prediction of Antiviral Activity of Andrographis paniculata Against NDV2K35 strain of Newcastle Disease Virus
The present study focused on molecular docking analysis of active principles of Andrographis paniculata with NDV2K35 proteins, a strain of Newcastle disease virus. The 3D structures of NDV2K35 proteins (receptors) viz. Haemagglutin-Neuraminidase protein (HN), Fusion protein (F), Matrix protein (M), Phosphoprotein (P), Large polymerase protein (L) and Nucleocapsid protein (N) were downloaded from Uniprot database, modelled using Swiss model analysis and validated by RAMPAGE: Ramachandran plot analysis. The active principles of Andrographis paniculata (ligands) viz. andrographolide, neoandrographolide and 14-deoxyandrographolide were downloaded from PUBCHEM, a database for chemical molecules. The docking analysis was carried out using Accelrys Discovery Studio 4.0 Client software. The results revealed that andrographolide interacted with all except M protein. The dock score of neoandrographolide was more than andrographolide with all the proteins but it failed to interact with F and M protein. The compound 14-deoxyandrographolide interacted with all proteins except F protein but the dock scores were comparatively less. The active principles were further screened for in silico pharmacokinetic and pharmacodynamic properties using Swiss ADME, a standard online tool and PASS online server. The active principles exhibited good GI absorption with bioavailability of 55 % and acted as substrate for p-gp. Of the three, neoandrographolide inhibited CYP3A4 which indicates the possibility for drug interactions. Toxicity analysis showed comparatively higher toxicity for neoandrographolide. Thus, andrographolide can be considered as a better choice for developing antiviral drug against Newcastle disease virus. However, the synergistic effect of all the three may possess better antiviral activity in vivo and needs further study.
Enhancing lentil yield and income of farmers through cluster frontline demonstration in Bundelkhand
Studies were conducted in the villages of Chachawali in the Niwari district of the rainfed Bundelkhand region of Madhya Pradesh during 2020–21; Anora in the Lalitpur district, and Semra and Bilati Karke in the Jhansi district of the rainfed Bundelkhand region of Uttar Pradesh from 2021–22. There were 15 front-line demonstrations in Chachawali, Anora, Semra, and Bilati Karke villages of the lentil variety IPL 316: five in Chachawali, five in Anora, two in Semra, and three in Bilati Karke. Each farmer had the opportunity to participate in a demonstration on a one-hectare plot of land. The goal was to improve lentil cultivation technology. Improved technologies included, among other things, high yielding variety, balanced fertilizer use (based on soil tests), and integrated disease and pest management. Chachawali, Anora, Bilati Karke, and Semra villages, in that order, got an average of 1235, 1285, 1408.33, and 1462.5 kg ha-1 from the demonstrations. There was an increase of 27.58, 23.58, 15.84, and 27.37% over the local yield. The average extension gap in Chachawali, Anora, Semra and Bilati Karke village was 2.65, 2.45, 3.13, and 1.92 q/ha, respectively, while the technology gap were 2.45, 2.15, 0.38, and 0.92q/ha, with the technology index being 16.33, 14.33, 2.5, and 6.11 percent in that order. The case study produced an average net return of Rs. 22525.9, 30112.0, 30247.0, and 3565.0 from the villages of Semra, Chachawali, Anora, and Bilati Karke, in that order, while the mean B:C ratio was 1.3, 2.1, 2.0 and 2.2. The data showed that superior varieties, packaging, and processing used in the frontline demonstration programme have contributed to increase in pulse productivity and profitability in the region.
PSV 512: A New High Yielding Dual Purpose, Early Duration Sorghum Variety PSV 512 for Telangana
The Sorghum culture PSV 512 (CSV 15 x SF 94006) recorded grain yield of 3586.6 kg/ha and fodder yield of 9198 kg/ha with superiority of 21.03 % and 7.86 % over the check PSV 1. The entry was also tested in All India level of AICRP testing with grain yield of 3349.4 kg/ha with superiority of 16.72%, 6.98 %, 21.02 %, 15.25 % over national checks of CSV 17, CSV 20, CSV 23 and CSV 27. It is early maturing variety (104 days) with semi compact symmetric panicle and grains are elliptic shaped with Grey-yellow colour endosperm. It is moderately resistance to shoot fly and stem borer pests and moderately resistant to grain mold disease. This entry is having higher consumer preference due to its low fat content in grains (2.81) and protein content of 10.81%. Hence, the promising culture PSV 512 has been proposed for new release during 2021 and released as Palem Jonna 1 for general cultivation in Telangana for both rainfed and irrigated condition.
Spatio-Temporal change detection Over a Decade in Panchkula District of Haryana, India
Geospatial technology provides economic, generic and detailed Land Use and Land Cover (LULC) products. Multi-date LULC products opportunitate change detection. Decadal temporality exposes patterns and trends of the settlement growth, infrastructure developments, forest cover change and agricultural land use. Study was done to evaluate LULC changes in Panchkula district of Haryana from 2010 to 2020. Quantification of spatial and temporal dynamics of land use/cover changes was accomplished over supervised classification of time series satellite images of IRS-P6 LISS-III for 2010 and Sentinel-2 (A & B) MSI for 2020 by applying post-classification change detection techniques in the GIS environment. Expansion of land cover was observed for built-up, water bodies and agriculture while reduction for wastelands, forest and grazing lands. Economic development due to Chandigarh region, micro-climate change in lower Shivalik and population increment were analyzed responsible for the detected change. Biophysically low-quality land parcels were marginalized without obtaining optimum economic marginality. High urban sprawl rate and deforestation highly impacted soil and environment resulting in degradation of habitat quality. This study illustrates the change over a decade from 2010 to 2020 covering the whole district of Panchkula, Haryana.
