| ABSTRACT: The root system architecture (RSA) of plants and its functioning play a fundamental role in a number of plant growth mechanisms including water and nutrient uptake. Optimization of the RSA is important for stable and increased plant productivity under adverse conditions. Despite its great importance, studying the RSA is notoriously laborious because of the difficulty of accessing the rooting system of plants. We developed a root phenotyping platform, PhenoRoots, which allows for the non-invasive study of plant RSA. The system was built using inexpensive material and was designed to provide medium throughput. Substrate or soil-filled rhizotrons are used to grow plantlets, whose roots are directly visible through a glass plate. An experiment... |

| Greenhouse study was conducted at the Weed Science, Crop and Environmental Sciences Division, IRRI in February-April, 2013. The objective was to assess the competitiveness of rice (IR64, Sabita, KDML105, Weedy rice (Oryza sativa f. spontanea Acc. 105798 (THA)) and six rice progenies derived from a cross between IR64 and Sabita that have high potential for competitiveness against weeds. The six progenies were SB561 (IR88633:1-66-B), SB562 (IR88633:1-67-B), SB604 (IR88633:1-136-B), SB665 (IR88633:1-138-B), SB708 (IR88633:20-69-B) and SB769 (IR88633:12-55-B). We evaluated the competitive ability of these rice genotypes under severe pressure from Echinochloa colona. The experimental design was RCB with 3 replications. Several rice shoot and root traits were... |
