It is said that robot can be used for multi-purpose use by changing end effector or/and visual sensor with its software. In this study, it was investigated what multi-purpose robot for fruit-production was using a tomato harvesting robot and a robot to work in vineyard. Tomato harvesting robot consisted of manipulator, end-effector, visual sensor and traveling device. Plant training system of larger size tomato is similar with that of cherry-tomato. Two end-effectors were prepared for larger size tomato and cherry-tomato fruit harvesting operations, while the res components were not changed for the different work objects. A color TV camera could be used for the both work objects, however fruit detecting algorithm and extracted features from image should be changed. As for the grape-robot , several end-effector for harvesting , berry thinning , bagging and spraying were developed and experimented after attaching each end-effector to manipulator end. The manipulator was a polar coordinate type and had five degrees of freedom so that it could have enough working space for the operations. It was observed that visual sensor was necessary for harvesting, bagging and berry-thinning operations and that spraying operation requires another sensor for keeping certain distance between trellis and end-effector. From the experimental results, it was considered that multi-operations by the same robot could be appropriately done on the same or similar plant training system changing some robot components . One of the important results on having function of multi-operation was to be able to make working period of the robot longer.

토마토황화잎말림바이러스(TYLCV)는 토마토에서 큰 경제적 손실을 초래하는 바이러스 병이다. 이병은 약제방제가 되지 않기 때문에 매개충인 담배가루이를 방제하거나 저항성 품종을 재배해야 한다. 본 시험은 시중에 유통 중인 토마토 품종에 대해 토마토황화잎말림바이러스에 저항성을 평가하였다. 토마토 품종별로 TYLCV 저항성 마커로 유전자 Ty-1과Ty-3 분석을 실시하였고, 아그로주입법으로 생물검정을 실시하였다. 대추형은 티티찰, TY 티니, TY 생생 II, TY 센스큐 등 4종, 방울형은 TY 엔도르핀, TY 스마프사마, 티아라 TY, 올레 TY 등 4종, 완숙형은 TY 킹덤, TY 에이스, TY 홈런, TY 알토랑, 도테랑 TY 위너, 스틱스 TY 등 6종에서 저항성유전자를 확인하였다. 유묘검정은 대추형과 방울형은 모두 유전자 분석결과와 일치하였으나, 완숙형은 저항성 품종에서도 일부 병징이 발현되는 경향이었다. 품종별 수량성은 대추형은 티티찰 대비 TY 티니가 우수하였고, 방울형은 스마일 대비 TY 스마프사마, 티아라 TY이 우수하였으며, 완숙형은 다복 대비 TY 에이스, TY 킹덤 등이 우수한 품종이었다.
