Abstract
Potato mop-top virus (PMTV) is the type member of the genus Pomovirus. PMTV is one of the most damaging potato infecting viruses due to the symptoms induced in the tubers. The symptoms caused by PMTV can be similar to the ones induced by another potato infecting virus, Tobacco rattle virus (TRV). Both viruses are known to generate great economic losses in Norway. Since the beginning of 2005, NCRI has as one of its objectives to enhance research on PMTV and will subsequently initiate studies on TRV as well.

Abstract
Organic Cow Comfort is an advisory tool in animal welfare, developed to secure animal welfare on organic dairy farms in Norway. The farm advisory tool consists of * A farm visit by a veterinarian and a production advisor both specialized in animal welfare and organic farming * An evaluation of herd health and welfare through welfare assessment * Advice on disease prevention and improve-ment of animal welfare * Follow up visit by an advisor looking at im-plementation of new initiatives * Counselling meetings with groups of farmer The evaluation of herd health and welfare is done with the help of checklists where animal based pa-rameters, farm management and operating systems, and human-animal relationship are recorded. A report is prepared after every farm visit with a health and welfare plan where specific measures for improve-ment of animal welfare are outlined.

Abstract
The performances of the plum rootstocks Plumina® Ferlenain, Ishtara® Ferciana, Jaspi® Fereley and the pentaploid open pollinated seedling of Mariana P 8-13 compared with St. Julien A as a standard, for the cultivars "Opal" and "Reine Claude GF 1119" were assessed in a field trial in western Norway at 60" North. This trial was one part of an international plum rootstock trial located in seven European countries and organized from INRA Bordeaux. Trees were planted in spring 1994; spaced 2.0 x 4.0 m and formed with a central leader as free spindles. Soil management was grass in the alleyways and herbicide strips 1-m wide along the tree rows. Tree vigour, yield, fruit size and yield efficiency were evaluated for the seven subsequent years. Tree size was significantly affected by the rootstocks. P 8-13 produced the largest trees for both cultivars as measured by trunk cross-sectional area. The smallest trees were produced on Plumina® Ferlenain for the cultivar `Opal" and on Jaspi® Fereley for `Reine Claude". The cultivar `Opal" was the most productive and gave three times larger crop than "Reine Claude" on average for the six cropping years. The "Reine Claude" trees came two years later into production than "Opal". There were small differences between the different rootstocks in productivity: However, the rootstock Plumina® Ferlenain produced significant lower crop than the other rootstock for `Opal". Trees on Jaspi® Fereley were the most yield efficient for `Opal" and Plumina® Ferlenain for `Reine Claude". The fruit sizes were in general medium to small for both cultivars and became little affected by the different rootstocks. The average fruit size was about 29 g for `Opal" and 22 g for `Reine Claude". Fruit quality characterized by the content of soluble solids was high for `Reine Claude" with average 20 % and 15 % for `Opal" and did not differ much between trees on the various rootstocks.
