Abstract:
This study examines the significance of understanding variability in plant height and tiller number in rice (Oryza sativa L.), crucial traits influencing yield potential and agricultural productivity. Plant height and tiller number, influenced by genetic, environmental, and management factors, exhibit considerable variability within and among rice varieties. Genetic diversity plays a pivotal role in shaping these traits, offering promising avenues for breeding high-yielding rice varieties tailored to diverse growing conditions. Environmental factors such as temperature, water availability, and soil fertility, as well as agronomic practices, further influence these traits. By elucidating the variability in plant height and tiller number, this study aims to inform the development of sustainable rice production systems, enhancing yield stability, resilience to environmental stresses, and resource use efficiency. The study reveals significant variations in rice plant height across seasons and treatments, with consistent averages despite diverse conditions. Investigating the interplay between plant height and tiller numbers, an experiment in the Kharif 2021 season showed a negative correlation. This suggests the importance of understanding how plant height influences tillering in rice germplasm lines.
