Sorghum is one of the most important crops worldwide. An accurate and efficient high-throughput phenotyping method for individual sorghum panicles needed assessing genetic diversity, variety selection, yield estimation. High-resolution imagery acquired using an unmanned aerial vehicle (UAV) provides a high-density 3D point cloud with color information. In this study, we developed detecting char...

Cambodia has a wealth of rice landraces (traditional varieties) adapted to different ecosystems. These are expected include diverse genetic resources that could be utilized in the improvement yield. A detailed investigation panicle architecture and grain size 173 Cambodian accessions revealed wide diversity these traits. The improved cultivars (grown mostly irrigated fields) was clearly reduced...

Harvest index is a measure of success in partitioning assimilated photosynthate. An improvement of harvest index means an increase in the economic portion of the plant. Our objective was to identify genetic markers associated with harvest index traits using 203 O. sativa accessions. The phenotyping for 14 traits was conducted in both temperate (Arkansas) and subtropical (Texas) climates and the...

False smut, caused by Ustilaginoidea virens, has recently been found in Arkansas. Plants infected by the fungus remain symptom-free until heading and it is difficult to see spores on contaminated seeds. Field tests were conducted in 2006 to determine the effect of false-smut inoculation of rice seeds on the yields of selected rice cultivars. Seeds were inoculated by vacuum infiltration in suspe...

proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...

to determine rice yield loss resulting from blast disease (magnaporthe grisea) at the corp's different growth stages, a field experiment was conducted at the rice research institute of iran, rasht. rice local cultivar hashemi was transplanted to 3×4m plots for the experimental treatments (time of disease evaluation) each treatment was replicated 4 times. under natural infection conditions,...
