abstract
During the Rabi season of 2020-21, field experiment was conducted as part of the All India Coordinated Research Project (AICRP) on Fodder Research and Physiology at the College of Agriculture, JNKVV, and Jabalpur (MP) to evaluate 16 oat genotypes using a Randomized Block Design with three replications. This study examines the developmental traits and physiological parameters of various oat genotypes, focusing on how these traits vary between genotypes. The results reveal significant differences in Phenophasic development, with IVTSC-3 displaying more extended periods for boot initiation, flower initiation, 50 per cent flowering, grain development, physiological maturity, and harvestable maturity compared to IVTSC-8, which had the shortest durations. Physiological assessments show that IVTSC-3 has the highest leaf area index, leaf area duration at 60 and 90 days, crop growth rate, and relative growth rate, while IVTSC-8 has the lowest values for all physiological observations. These findings underscore the importance of considering genotype-specific responses in oat growth dynamics, providing vital insights for oat breeding programs and agronomic practices that aim to enhance crop productivity and resilience.
