Based on current predictions of the increasing global population, rice production needs to be increased by more than 50% to meet the future demand of the rice-eating countries. It has already been demonstrated that cereal crop yield could be increased by modifying root architectural traits for production under limited resources like water and nutrition. The main objective of the study is to assess the rooting behaviour of a panel of Boro and Amon rice cultivars collected from the Bangladesh Rice Research Institute (BRRI). Materials and Methods: Two established screening methods, hydroponic and soil-filled glass rhizotron system were used to assess the panel of Boro and Amon rice cultivars. Using these two methods, deep and shallow-rooted cultivars were identified. A panel of 16 rice cultivars was used in this study. Results: Assessing the 16 cultivars in a hydroponic system, 98% variation was observed by the genotype at day 46 (p = 0.001). Soil filled glass rhizotron was used to assess six of these accessions along with two check varieties revealing strong genotypic variation. Analysis of variance (ANOVA) showed a 73.37% variation explained by the genotype (F = 13.20, p = 0.001) at 46 days after sowing. Conclusion: Assessing all the traits, the rhizotron data revealed that BR 22, BR 60, BR 19 and BR 3 has the deepest rooting systems. The trait information could be useful to breed better cultivars, especially in drought-prone regions.]]>Caicedo, A.L., S.H. Williamson, R.D. Hernandez, A. Boyko and A.
