Assessment of Genetic Variability, Heritability and Genetic Advance of Okra Genotypes (Abelmoschus esculentus L. Moench)

Paper ID- AMA-08-04-2022-11291

The experiment was performed in Randomized Complete Block Design (RCBD) with three replications and germplasm evaluated at Vegetable Research Farm, Kalyanpur, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (Uttar Pradesh) during Kharif season of 2018-19. Analysis of variance revealed significant variability among the strains of okra for all character’s studied. Heritability estimates varied from (60.80%) for length of fruits to (99.70%) for number of seeds per fruit. It was partitioned as very high (above 90%), high (70- 90%), medium (50-70%) and low (less than 50%).heritability estimates were observed very high for number of seeds per fruit (99.70%), days to 50% flowering (99.0%), yield per plant (98.80%), number of fruits per plant (98.50%) and plant height at 45 days. High for diameter of fruit (89.20%), first flowering node (88.30%), Plant height at 90 days. Medium estimation of heritability was recorded for length of fruits. Phenotypic variances range between days to first flowering (4.67) and plant height at 45 days (20.08) The phenotypic coefficient of variations was highest for characters viz., plant height at 45 days (20.08%), number of fruits per plant (17.37%), and number of seeds per fruit (17.34%). and genotypic variances ranging between days to first flowering (4.63) and plant height at 45 days (19.79). High genotypic coefficient of variation was noted for plant height at 45 days (19.79%), number of seeds per fruit (17.38), number of fruits per plant (17.24%) and plant height at 90 days (15.56%). Genetic advance expressed as percent of mean was high (>20%) for plant height at 45 days (40.18), no of seeds per fruits (35.63), number of fruits per plant (35.25), plant height at 90 days (29.94), fruit yield per plant (27.97), diameter of fruits (27.55) and first flowering node (21.87). While the moderate genetic advance (<20 to 10%) was observed for fruit length (15.5) and days to 50% flowering (10.5).

Findings of cartap hydrochloride alternative to the monocrotophos against coconut black headed caterpillar, Opisina arenosella (Walker) using syringe method in coconut palm

Paper ID- AMA-08-04-2022-11290

The present study was conducted at Halebudanur village in Mandya district in Karnataka, India. The syringe method, a novel approach of insecticide administration into the coconut palm was applied using an eco-friendly, animal originated insecticide cartap hydrochloride 50% SP for the management of coconut black headed caterpillar, Opisina arenosella. The results of the study found that, all dilution of cartap hydrochloride 50% SP injected to base of the coconut palm effectively achieved 100% larval mortality of O. arenosella and protection lasted up to 90 days with no phytotoxic symptoms to the leaflets of treated palms. The syringe method has revealed quicker absorption of insecticides, easy to implement and no secondary infection or mechanical damage to the palm tissues and can be useful in coconut palm in managing O. arenosella population.

ICT in Agricultural Higher Education: Investigating the flowers and flaws

Paper ID- AMA-08-04-2022-11289

This study aimed to determine the impact of digital technologies on agricultural graduates of Indian State Agricultural Universities. An investigation into the effects of digital tools on academic development with the students was conducted. The sample consisted of 1438 undergraduate students and 327 faculty members belonging to ten State Agricultural Universities of India comprising twenty diverse agricultural sciences colleges selected through the Simple Random Sampling method. Data were collected with the help of a semi-structured interview schedule developed for the purpose, along with informal observation and discussions. The students under study agreed on the impact of ICTs in saving time, giving accurate information, easing the exchange of ideas, and keeping up-to-date information. Though ICTs are supposed to be associated with a positive impact, there are still some negative impacts of ICT as perceived by the students. Most of the students linked ICT with health problems/lack of physical activity, reduced personal interaction and a threat to security and privacy. Students are reluctant to attend classes, insufficient use of the library, wastage of time in net surfing, over-dependence on ICT, social media distraction, spurious information, duplication of research and critical reading and writing skills of students To attract students to attend classes, blended learning and innovative ICT methodologies should be used apart from PowerPoint Presentations.

Soil Aggregate and Organic Carbon Fractions in the Foothill Himalayas Under Different Landuse Systems

Paper ID- AMA-08-04-2022-11288

Soil aggregates and organic matter are measured to be essential indicators of soil quality. The objective of this study was to determine landuse effects on the distribution of soil organic carbon (SOC) associated with aggregate size fractions. Bulk soil samples were collected from incremental soil depth (0-15, 15-30, 30-60 and 60-100 cm) under five landuse systems; forest, horticulture, agriculture, pasture and degraded lands. Soil samples collected from these landuse were analyzed for aggregate stability after dry and wet sieving into three aggregate size classes (2.0 mm, 2.0-0.25mm and <0.25 mm) and the concentration of SOC fractions in each landuse. Bulk densities were greater in degraded land (1.54-1.57 g cm-3) than agriculture lands (1.52-1.53g cm-3). The macro-aggregates (˃2.0 m) were higher in surface soil of pasture, agriculture and degraded whereas subsurface soil layer were higher in forest and horticulture land. Aggregate stability varied in the order of pasture˃forest˃horticulture˃agriculture ˃degraded lands in surface soil. SOC fraction decreased with increasing soil depth under different landuse systems. Our data supported the hypothesis that vegetation (fruit tree plantation) landuse systems and the proportion of aggregates are suitable indicators of SOC build-up and may therefore have a better potential for SOC sequestration than the degraded lands.

Molecular Marker Assisted Early Generation Selection Of Blast Resistance Gene (Pi54) In Rice

Paper ID- AMA-07-04-2022-11283

Blast of rice caused by the fungus Magnaporthe oryzae (Hebert) Barr is one of the major constraints in rice production in Jammu and Kashmir; and exploiting host plant resistance by utilizing resistance (R) genes is considered to be the economically viable and environmentally safe approach to tackle this disease. Of about 100 blast resistance genes identified so far, Pi54 is reported to provide broad spectrum resistance to prevalent races of M. oryzae under North Western hill ecology. Pi54 is a cloned and characterized gene with availability of closely linked and functional markers. The present study aimed at selecting plants homozygous for the blast resistance gene Pi54 in F2 population of the cross K 343/DHMAS. A total of 25 SSR markers were used, out of which 4 showed polymorphism with respect to these two parents; indicating the genetic similarity in their backgrounds. Out of the three SSR markers reported closely linked to Pi54 locus i.e. TRS26, TRS33 and RM206, marker RM 206 (0.7cM from Pi54 locus) was utilized for selection of Pi54 positive plants in F2 population as it resolved clearly through agarose gel electrophoresis. The hybridity of the F1 plants was confirmed using polymorphic SSR markers (RM110, RM220, RM240, and RM263). The F2 plants along with parents were sprayed with suspension of PLP-1 culture of M. oryzae at 5-6 leaf stage and incubated under standard conditions for pathological phenotyping. Out of the 27 plants, 8 plants showed moderate to highly susceptible response. Other 19 plants showed immune to resistant reaction. The genotyping of parents and individual F2 plants using linked marker RM206 showed that out of 27 plants, only 7 plants had target gene in homozygous dominant state and were thus identified as Pi54 positive plants which could be utilized as superior genetic stocks.
