Abstract

This experiment was carried out to evaluate the specific gravity and glucose content of potato germplasms and to identify varieties with high specific gravity and low glucose content for a total 282 varieties in 1997, 1998, 1999, and 2001. Highly significant correlations, for specific gravity and glucose content, by analysis of correlation coefficient were shown among those years. Therefore, these two characteristics are very useful as a selection index to improve breeding efficiency for processing potato in early generations. In this experiment, a group of 38 varieties including Daegwan 39, Katahdin, Konahubuki, and Darita, which showed specific gravity in excess of 1.080, was selected for starch processing, another group of a 170 varieties including Daegwan 22, Alamo, Hokkaigogane, and Spunta, was selected as having low glucose content of less than 0.25%. Also, a 18 varieties including 76C36-43, Atlantic, Pentland Dell, Record, and Waseshiro were selected as the group of both high specific gravity and low glucose content for chip and french fries.

가공용 품종 육성을 위한 육종재료를 선발하고자 1997년, 1998년, 1999년 그리고 2001년의 4년 동안 총 282계통의 감자 유전자원에 대하여 가공형질과 관련된 비중과 glucose 함량을 조사하였다. 비중과 glucose 함량은 실험 연차 간에 높은 상관을 나타냄으로써 우수한 가공형질을 가진 유전자원을 조기에 선발하여 교배에 이용하는 것이 가능할 뿐만 아니라, 가공용 품종 육성을 위한 육종프로그램에서 육성초기세대의 선발지표로도 이용될 수 있어 가공용 품종 육성의 효율성을 높일 수 있을 것으로 기대된다. 이 실험을 통하여 비중이 1.080 이상으로 전분 가공용으로 적합한 자원으로는 Daegwan 39, Katahdin, Konahubuki, Darita 등 38계통, glucose 함량이 0.25% 이하로 적은 자원으로는 Daegwan 22, Alamo, Hokkaigogane, Spunta 등 170계통, 그리고 비중이 높고 glucose 함량은 적어서 칩이나 프렌치프라이용으로 우수한 계통으로 76C36-43, Atlantic, Pentland Dell, Record, Waseshiro 등 18계통이 선발되었다.
