MAFF UPDATE No.733 (Published on February 4th, 2011)





Select "Ten outstanding topics of Agriculture,Forestry and Fisheries Research Results,2010" 


Secretariat of the Agriculture, Forestry and Fisheries Research Council selected "10 outstanding topics of  Agriculture, Forestry and Fisheries research results,2010"

in cooperation with the agricultural technology press club. 


Ten outstanding topics of Agriculture,Forestry and Fisheries Research Results; 

Ten topics of which outcomes can be considered to have excellent contents and to draw high social interests were selected from last year's every news articles of agriculture, forestry and fisheries research results, achieved by private sectors, universities, public research institutes and research institutes of independent administrative agencies. The selection was made in cooperation with the agricultural technology press club (including 29 companies, such as agricultural related specialist papers and magazines related to agricultural technology).


The selected ten topics;

(a) The world's first success of “completed cultivation of eel “, paving the way to the production of eel, independent of natural resources

Fisheries Research Agency succeeded in obtaining larval eel from artificially fertilized eggs, of which eggs and sperms were from artificially hatched, grown and matured eels.

The process of “Completed cultivation of eels” was realized by their mature satisfactorily. Stable supply of eel and protection of watery resources can be expected.


(b) Discovery of gene which is effective for increasing rice harvest -Challenge to prevent people from food crisis through increased grain production-       

Nagoya University has discovered a rice gene “WFP” which is effective to dramatically increase rice harvest.

These findings are expected to raise yield amounts of rice and gramineous crop such as barley or maize.


(c) The development of new manufacturing technology of bread made by 100% rice-milled flour ( Gluten free) -Contribution to improve the food self-sufficiency rate and stimulate rice flour demand-

National Food Research Institute, NARO has developed the new bread manufacturing technology of 100% rice-milled flour (Gluten free).

The new bread made by rice flour is free from gluten and salt which were indispensable to make popular rice bread, and instead of that,  “glutathione”, a kind of protein, was added to successfully make puffy rise-milled bread. Improvement of food self-sufficiency rate and stimulating rice flour demand can be expected, and it is also effective to people who have wheat allergy. 


(d) Coating seeds with powdered molybdenum compounds improve seedling establishment in direct seeding rice cultivation -Development of  simple and low-cost method for direct seeding rice cultivation-

National Agricultural Research Center for Kyushu Okinawa Region, NARO clarified that coating seeds with powdered molybdenum compounds improve seedling establishment in direct seeding at submerged paddy field. Compared to present methods, this method requires only 1/10 of material costs and provides easy procedure to process seed.

This method is expected to become fundamental technology of direct seeding rice cultivation.


(e) Decode whole-genome nucleotide sequence of “Koshihikari” -define origin and evolution of Japanese rice-

National Institute of Agro biological Sciences has decoded the most of genome nucleotide sequence of ”Koshihikari”, and found approximately 67,000 places of “Single nucleotide polymorphisms”,

where only 1 base is different from the compared “Nipponbare” which has already been decoded. In addition, the origin of Koshihikari rice genome has been revealed.

These findings are expected to effectively develop superior rice varieties.


(f) Successful giving birth to calves from Ovum Pick-Up (OPU)-derived ova with storage at super low temperature

Techniques of long-storage of bovine ova have been studied in Saga Livestock Research Institute.

A research team in the institute succeeded to have calves from OPU-derived ova with twice freezing steps; before and after in vitro fertilization.

The success of long-time storage of ova is expected to improve the breeding of cattle.


(g) Contribute to genome analysis of soybean, the major legumes crop-Expect useful soybean research and its effective selective breeding-

Japan-US international research team including RIKEN worked together, decoded 85% of soybean's genome, and discovered approximately 46,000 genes.

Improvement of efficiency of soybean breeding is expected.


(h) Development of transportation methods keeping high freshness of vegetables and fruits by using electromagnetic wave sterilization and nanomist

Research groups including Kyushu University have developed electromagnetic radiation sterilizer for vegetables, using infrared and ultraviolet rays and high humidity container for low temperature

transportation, which is highly effective for keeping freshness.

Developed containers can be used in stationary preservation warehouses, and low-cost transportation maintaining high freshness of vegetables and fruits can be expected.


(i) Establish a technology of practical purification against cadmium contaminated paddy soil by cleaning-method in soil -remove cadmium from paddy soil at low cost-

National Institute for Agro-Environmental Sciences worked with Nagano-Prefecture Agricultural Experiment Station, etc. to develop a technology, the ‘soil cleaning method in paddy soil' to purify soil

contaminated by cadmium on site. Cadmium is eluted by adding water and iron chloride into contaminated paddy field, which makes the soil acidic, and the contaminated wastewater is processed to remove

the cadmium. Cadmium concentration in rice decreases by 70% to 90% comparing to the case of non-treatment.


(j) “Process of sugar and ethanol complex production” developed!-successfully proved with the experimental plants, moving up to verification at the practical level-

Asahi Breweries co., Ltd and National Agricultural Research Center for Kyushu Okinawa Region, NARO have developed a system that enables to produce massive bio-ethanol by a new variety of sugarcane

including 50%-higher biomass production and 30%-larger sugar yield compared to the conventional varieties for making sugar.

Activation of sugarcane industry in South-Western Islands and effective greenhouse gas reduction can be expected.
