1. Acquisition of DNA-markers relating to traits for biofuel production and its application to breeding
 This research is aimed to select Eucalyptus elite clones solely for a biofuel production purpose in which the amount of accumulated cellulose per unit area becomes largest during the standard harvesting period. The DNA-marker assisted breeding technique will be developed and utilized at the stage of selecting plus trees among the seed-grown population in Eucalyptus plantations.
 In this fiscal year, we carried out phenotyping such as growth rate, basic density and alpha-cellulose content from approximately 1,000 samples. We also determined the effective DNA-markers and selected the 32,000 markers and acquired more than 5 DNA markers in each phenotype. We generated an equation to estimate the phenotype. The correlation coefficient was over the 0.5 in each phenotype at the current moment.

2. Development of large-area soil evaluation system using a soil sensing technology
 The purpose of this research is to develop a large-area soil evaluation system for Eucalyptus plantations in northern Brazil. In particular, it is to develop a tractor attached soil analyzing system for detecting the Vis-NIR reflectance spectra in soil.
 In this fiscal year, we determined the specification of the soil sensor from the survey at the plantation site in northern Brazil. In the soil analysis of several chemical properties and soil physical properties, the distributions of over 20 parameters were relatively small. The soil investigation was shown that rich nutrition-layer was 10-20 cm under surface. Then it is assumed that the measurement depth of the chisel on the soil sensor was 20 cm. There were many remains of roots or stems in forest plantations. Hence, equipment for protecting soil sensor was prepared. Finally the soil sensor was finished in Japan.

3. Development of biomass volume evaluation system by terrestrial 3D laser scanner
 This research is aimed to estimate biomass of branch and trunk in Eucalyptus plantation in northern Brazil. For the biomass estimation, we are carrying out data analysis, algorithm creation and software development of survey systems, with a terrestrial 3D laser scanner (3DLS) and a UAV (Unmanned Aerial Vehicle).
 In this fiscal year, we acquired 3D point clouds of single tree by 3DLS. We developed the algorithm to calculate the tree volumes and the practicable software. The difference between actual wood volumes by measurement felling trees and estimated wood volumes by 3DLS was 0.2%. This value was much accurate as compared with previous method (7.3%). We have also been developed the software for measurement of the biomass of branch and leaf. We investigated a ratio of biomass at weight basis between trunk, branch and leaf by felling down several trees. The ratio of the trunk, branch and leaf at the 5 years old is 91.2:5.5:3.3. These data were used development of the software for biomass measurement.
