A field experiment involving 30 genotypes of maize was carried out under the field condition during Rabi 2021-2022 to study the association of yield contributing characters among themselves along with direct and indirect effects on grain yield per plant and identify the genotypes which are highly efficient with respect to different PEG induced drought stress. The results of the study revealed that plant height, leaf length, ear height, number of grain rows per cob, number of grains per row, cob girth, cob weight, biological yield per plant, 100 grains weight and harvest index showed positive significant association with grain yield per plant both at genotypic and phenotypic levels. Plant height showed positive significant association with leaf length, ear height, number of grain rows per cob, cob girth, cob weight, 100 grains weight, biological yield per plant and grain yield per plant. Days to fifty per cent silking, anthesis to silking interval, days to maturity, number of grain rows per cob exhibited negative direct effect while number of cobs per plant, leaf width, cob length, cob weight, biological yield per plant and harvest index exhibited positive direct effect on grain yield per plant. For improvement of seed yield, attention should be given for traits such as cob weight, biological yield per plant and harvest index which showed high positive correlation coefficients with a considerable direct and indirect effect on grain yield. MGC-192 has shown high root length, shoot length, seedling length, seedling dry weight, seedling vigour index 1, seedling vigour index II, germination percentage and MGW-392 has shown high relative water content under PEG induced stress condition, hence this genotype is suggested for future selection.

A biosensor is a self-reliant integrated device that is proficient in providing specific quantitative or semi-quantitative analytical information. It has been using a biological recognition component that is in direct spatial contact with a transduction component. It is an appliance that consists of two main parts: a bioreceptor and a transducer. Bioreceptor is a biological component that recognizes the objective of an analyte and a transducer. A physicochemical detector component has also been employed that converts the recognition incident into a measurable signal. All the biological materials including enzymes, antibodies, nucleic acids, hormones, receptors, organelles, or whole cells can be used as sensors or detectors in a device. Biosensors can provide low-priced and highly capable devices for being used in other day-to-day applications. It has multifarious potential applications of various types such as monitoring of treatment, disease progression, drug discovery, food control, and environmental monitoring as well as it continues to play a crucial role across numerous fields including biomedical diagnosis. In this review, we give a general introduction to biosensors and their applications, including a brief historical overview. Keywords: Biosensor, Bio-receptor, Transducer, Analyte, Detector.

Production of crops is troubled by major issues called abiotic stressors. The most important sensitive stages to abiotic stress are during seed germination and seedling growth. Seed priming promotes faster, more synchronised emergence and enhances the performance of seedlings. Different kinds of chemicals are utilised for seed priming today. At the same time the issue of environmental concerns is coming from every corner. Hence organic farming is getting due considerations. The present study was aimed to investigate the effect of matrix priming with biostimulants on germination and seedling quality of carrot seeds under abiotic stress conditions. The experiment was conducted at the Seed Science and Technology Laboratory of Ankara University under controlled conditions. Moisture stress was simulated using PEG-6000 at different concentrations (0, 10 and 15% PEG), while salinity stress was simulated using NaCl at different molarity (0, 50 and 100 mM), which have same osmotic potential with the corresponding PEG concentrations. All matrix priming treatment performance of seeds and seedlings. Seaweed alone and its combination with butenolide showed the best performance for all the parameters. The GP of nonprimed low-quality seeds of carrot at -0.30 MPa was 0% but it was 32% for seeds primed with SW. Likewise, for low quality seeds at 100 mM salt concentration, maximum seedling height of 4.7 cm was recorded in SW while the control was 0 cm. Biostimulants can be used as organic seed priming agent to enhance seed quality.
