Genetic Analysis of Homogenous and Heterogeneous Populations in Mungbean [Vigna Radiata (L.) Wilczek]

Paper ID- AMA-11-12-2023-12768

Combining ability analysis for yield and yield components of mungbean (Vigna radiata L. Wilczek) was conducted using an 8 x 8 diallel mating system both in F1 and F2 generations. Both gca and sca mean squares were significant for all the eleven characters in F1 and F2 generations, former being more pronounced for clusters per plant, pods per cluster, pods per plant, pod length, seeds per pod, 100-seed weight and seed yield per plant in F1 and for all the characters except days to maturity, seeds per pod and 100-seed weight in F2. The parent K 851 was a good general combiner for seed yield per plant, days to maturity, plant height, primary branches per plant, clusters per plant, pods per plant and seeds per pod in both generations. While Pant-M 4 was good general combiner for seed yield per plant, plant height, pods per cluster and pods per plant over generations. Parents RMG 62 and Asha were the best combiners for early flowering. GM 4 had good general combining ability for seed yield in F1, but for pod length and 100-seed weight in F1 and F2. The crosses showing high sca effects for seed yield also had significant and positive effects for at least two important yield components.

An Assessment of India’s Export Potential of Silk and Silk Products Covered Under Chapter 50

Paper ID- AMA-11-12-2023-12767

An assessment of Export Potential was done using ITC’s (International Trade Centre) Methodology for the Indian product category ‘Silk’ falling under chapter 50, at HS four and six-digit levels. Comparisons were also made with Italy and China, the next two close competitors of India in this product category. The analysis proves that the industry needs an overhaul in terms of establishing better production units with the right and innovative technologies. India’s export potential could be high only for two product categories HS 5003 (Silk waste, incl. cocoons unsuitable for reeling, yarn waste, and garneted stock) and HS 5007 (woven fabrics). The latter has good export potential but India cannot harness it, due to poor market access in many countries. The bilateral relationships may improve India's access in these markets, especially Vietnam and Korea. China is ahead due to its first-mover advantage and immense investment in technologies under changing market conditions. India needs to invest in technologies for the upliftment of the sector. India’s National Silk Policy looks promising given right monitoring mechanisms work to ensure its grassroots-level implementation and the commitment of state governments. Further Geographical Indicators must be promoted widely and database management for the public eye will help in gaining worldwide attention.

Assessment of greengram (Vigna radiata L. Wilczek) genotypes for Aluminium toxicity tolerance and Phosphorus Uptake Efficiency (PUE) under Hydroponic condition

Paper ID- AMA-08-12-2023-12761

Thirty-two genotypes of greengram were examined for their tolerance to aluminium (Al) toxicity using the growth response and haematoxylin staining techniques. Root staining score, post-staining root regrowth, and root and shoot length were the main characteristics to determine Al toxicity tolerance. With the exception of the root staining score, there was significant variation in the greengram genotypes' tolerance to Al toxicity. During screening with varied concentrations of Al, the amount of 150 µM Al produced the best discrimination power between the genotypes of greengram. Based on the score, genotypes could not be distinguished well using root staining. On the other hand, greengram genotypes for aluminium tolerance at the seedling stage were distinguished by the root regrowth that occurred after staining. When exposed to 150 µM aluminium concentration, the genotypes Pusa 1031, Pusa Ratna, and MH-421 showed long root regeneration (1.38, 1.20, and 1.10 cm, respectively), whereas Meha and Pusa 1431 showed short root regrowth (0.16 and 0.13 cm, respectively). Additionally, this study demonstrated that greengram Al tolerance is constant throughout the plant growth stage, allowing selection for enhanced Al tolerance to occur during the seedling growth stage. Genotypes Pusa 1031 and P 672 had shown highest P content (4.53% and 4.37 %) and PUE (254 % and 245%) under control conditions and under Al toxic conditions, genotypes HUM-16 and Pusa Ratna had shown highest P% (2.17 and 2.15) and PUE (121 % and 120%). This study revealed that different genotypes of greengram had different potential to perform differently under Al toxicity condition in acidic soils.

Common Indian earthworm species, Pheretima posthuma (Clitellata, Megascolecidae), resulted enhanced dispersal of entomopathogenic Nematodes, Steinernema abbasi and Heterorhabditis indica (Nematoda: Rhabitida)

Paper ID- AMA-05-12-2023-12757

Entomopathogenic nematodes (EPNs) have excellent bio control potential for management of insect pests of economic importance. In the present study, dispersal of EPN species, Steinernema abbasi Elawad, Ahmad and Reid, 1997 and Heterorhabditis indica Poinar, Karunakar and David 1992 by common Indian earthworm species, Pheretima posthuma Vailliant, 1868, as well as safety of using both these EPN species towards P. posthuma were investigated under laboratory conditions. Vertical dispersal (upward as well as downward) of both entomopathogenic nematode species combined with earthworms was carried out in autoclaved soil filled in polyvinyl chloride pipe columns. Here after, the toxic impact of these EPN species towards earthworms applied at two different concentrations in autoclaved soil was studied. Upward as well as downward dispersal of EPNs was significantly greater in soil in the presence of earthworms relative to soil without earthworms. Also, the tested nematode species were found to be safe towards P. posthuma as they did not cause any earthworm mortality up to 3 weeks of treatment when applied at a dose of as high as 200 infective juveniles/ gram soil. It is concluded that presence of earthworms in the soil can have positive impacts on the host finding ability of the entomopathogenic nematodes due to their increased dispersal. Also, the tested EPN species had neutral impacts on survival of the earthworm species, P. posthuma. Therefore, we need to consider the role played by species-specificity in these interactions in order to use them effectively in devising bio-control programmes at field level.

ULTRASONIC AND DIRECT MEASUREMENT OF BACK FAT THICKNESS IN BARROWS

Paper ID- AMA-04-12-2023-12755

Ultrasonic instruments have an important role in the prediction of back fat depth of live pigs, mainly for the purpose of selecting animals for leaner pork production. Backfat in pigs consists of water, collagen, and lipid. Backfat thickness is one of the significant parameters to consider when selecting female pigs into breeding herds since it dominates a number of reproductive performances. The present study on measurement of back fat thickness (BFT) in thirty-six Landrace crossbred (62.5% Landrace and 37.5% Desi) live barrows and carcass was carried out at Swine production farm, Indian Veterinary Research Institute, Izatnagar, Utter Pradesh. The average BFT in live barrows was done by using back fat scanner one day before the schedule of slaughter and direct measurement of BFT in carcass were also observed after slaughter. In live barrows the BFT were measured at locations are midpoint of shoulder above elbow, middle of back where last rib joins the vertebrae and rump, straight above the stifle joint and average was calculated. The overall measurement of BFT of live barrows and carcass BFT (cm) were 1.81±0.44 and 2.12±0.08, respectively. The results showed that there was no significant difference of back fat thickness on live barrows and carcass were observed among the treatment groups. However, in dietary group had significantly highest back fat thickness measurement had been observed both live barrows and carcass. The BFT values were in values were in dietary group D3 (2.24±1.23), D2 (1.64±0.65) and in D1 (1.55±0.058) and in carcass D3 (2.59±0.12), D2 (1.92±0.10) and in D1 (1.85±0.058) respectively. However, values of BFT in lives barrows and carcass was almost similar. Based on this study it can be concluded that the Ultrasonic scanner is more reliable for prediction of BFT at growing stage of pigs and it can useful technique for selection of breeding stock for better genetic improvement and also for lean meat production.
