USA, travel, rice tour
Rice Extension led a group of 20 people on a 10 day tour to the Sacramento Valley in California in August 2016 to learn about the Californian rice industry. There were a mix of rice growers and industry representatives from across all age groups and areas. The tour visited farms, processors, research facilities, industry representative groups, water corporations and industry advisors. The tour finished with some recreational activities, including a visit to the Napa Valley and some time in San Francisco at the baseball and a bay tour. The participants thoroughly enjoyed the tour, which allowed them to make international and local connections, added to their personal development and stimulated them to review practices on their own farms. Rice Extension is currently investigating tour options for 2017.

|A Gene Machine for Functional Genomics of Rice||Genetics, RIRDC||Upadhyaya, N.M, Zhu, Q-H, Dennis , L.||2006||RIRDC|
Gene, Machine, genomics, seedling vigour, mutants, quality.
This RIRDC report presents the findings from the project A gene machine for functional genomics of Rice. The report is presented in chapters each focussed on a specific section of the project. The key chapters are Development of tools and resources for producing rice insertion lines (Rice Gene Machine), A library of rice insertion lines – Rice Gene Machine, Rice Gene Machine – national and international collaboration, Case studies of gene identification using the Rice Gene Machine, Mining seedling vigour genes using the Rice Gene Machine - trait targeted research. Each chapter contains, background, objective materials, methods, outcomes and progress. The overall outcomes was the development of a resource for rice functional genomics this project has made significant contribution in the form of a Rice Gene Machine -a library of insertional mutants. Using insertional mutants this research group has already identified several genes controlling plant growth and development. . This project also in conjunction with NSW Agricultural Genomics Centre, has produced new constructs and protocols for improved efficiency of mutagenesis and subsequent screening for stable insertion mutants. This research group has now developed collaborations with national and international laboratories to expand the Rice Gene Machine resource development as well as utilization. Using this Rice Gene Machine, this group is now concentrating on identifying genes controlling important agronomic traits such as seedling vigour and grain quality.
|Sucessful genetic engineering of Australian rice ||Breeding, Genetics, IREC Farmer Newsletters||Abedinia, M||1996||IREC|
Genetics, genetic engineered, transgenic rice, microsprojetile bombardment, Australian rice
This IREC Farmer Newsletter article presents the results of a project funded by RIRDC Rice of a team of researches including the Australian rice breeders, cereal chemist and researchers from Queensland Agricultural Biotechnology Centre (QABC). The team have successfully genetically engineered Australian rice. The report presents information on transgenic rice and microsprojetile bombardment technique. The project was successful in achieving its aims and the ability to modify Australian rice.
** Though this technique is possible it is not used commercially available Australian rice. There is no genetically modified Australian rice commercially available in 2016. ***
|Development of molecular markers for rice breeding in Australia ||Breeding, Genetics, IREC Farmer Newsletters||Abedinia, M||1998||IREC|
Molecular markers, DNA, genetics, microsatellites, semi dwarfism
This IREC Farmer Newsletter presents and overview of the RIRDC project USC2A that was investingating the development of molecular markers in rice breeding. The article presents the fist year results. These molecular markers will be useful for the maintenance of pure lines, the identification of varietal mixture and making the development of molecular markers for further traits a straight forward process.

genetic engineering, Australian rice, cold tolerance, sub zero temperatures, wild rice, Zigania palustris
This IREC Farmer Newsletter article presents an update on research into genetically modifying Australian rice for cold tolerance. This was a RIRDC rice (USC1A) undertaken at Southern Cross University with assistance of Australian rice breeding program. The aim of the project was to produce transgenic rice plants by isolating cold tolerance genes from Zizania or Potamphila and then introducing into the Australian rice variety Jarrah using biotechnology techniques. The trial was still underway at time of printing.
*** Important to note in 2016 still not geneticially modified rice is available***

|Agronomic and molecular aspects of osmoprotectant application and cold tolerance in rice||Cropping Systems & Water Management, Genetics, RIRDC||Bodapati, N, Fukai, S, Williams, R||2006||RIRDC|
Osmoprotectant, glycinebertaine, spermine, establishment, foliar application, cold tolerance, molecular., gibberellic acid
This RIRDC reports on the project presented three major objective including developing a seed treatment method using glycinebetaine or spermine (osmoprotectants) to increase seedling establishment at low temperature. The second objective was to examine if foliar application of these solutes would increase yield of cold stress affected rice plants under laboratory and field conditions. The third objective was to obtain molecular and physiological information on the role of osmoprotectants to increase cold tolerance and this may form a basis to genetically engineer rice plant to produce osmoprotectants naturally. The project was undertaken with the use of laboratory experiments undertaken on seed treatments, mechanism of action, gibberrellic acid, cold tolerance at reproductive stage and molecular gene/regulation. Field experiments focussed on seedling experiments and reproductive cold damage.
The recommendations from this project suggest that there is a strong possibility of increasing seedling establishment and mid season cold tolerance by using GA, polyamnies and/or glycinebetaine. However the author believes that further larger scale field trials be conducted before further advising farmers to use such products.
|Measurements of losses from on farm channels and drains ||Cropping Systems & Water Management, Rice CRC||Akbar, S||2001||CRC Rice|
Irrigation, channels, drains, Idaho seepage meter, EM 31, electrical conductivity (ECa), soil texture, salinity, inflow, outflow.
This CRC funded project had two main aims including to determine the magnitude of percolation losses attributable to on-farm channels and drains. The second major aim was to consider approaches and for need to identify problem were and to consider likely remediation techniques. The project was undertaken
within selected farms in Coleambally and Murrumbidgee Irrigation Areas in southern NSW during the irrigation seasons of 1997/98, 1998/99 and 1999/00. To undertake the points of infiltration the Idaho Seepage Meter was used as a result of being rapid, direct and cheap. The study investigation were undertaken on farm trials using EM31, Peizometer measurements, soil texture and salinity measurements, channel distribution on farm, channel seepage metres, inflow and out flow and depth of flow channel width. The conclusion of the project indicated that EM31 reading were strongly related to change in seepage rate. It was stated that area’s of low conductivity compared to surrounding areas inferred that the leakage rate was high. It was also stated soil types and water depth in the centre of channels or drains are the most important channel factors with respect to seepage in the on-farm channels and drains. It was indicated that seepage magnitude is affected considerably by the width of the channel. The EM31 measurements provide very good results for the identification and quantification of seepage. Additionally the combination of the Idaho seepage meter and EM31 measurement provided a good technique for the identification and quantification of seepage from sections of the on-farm channels and drains.
