Abstract

Influence of different cultivated areas on the processing-grade tuber yield, specific gravity, reducing sugar content and tuber qualities of five promising varieties was studied to get the basic information for selecting potato varieties with good processing quality under the different cultivated conditions on Korea. The average total tuber yields of 5 tested varieties at the 2nd harvest time was 3,.051kg/10a in Daekwallyoung. The processing-grade tuber yield of the late-maturing variety of Gemchip was over 3.2 tons per 10a, whereas that of late-maturing variety, NS1 was 2.8 tons per 10a. The dry matter content of the tubers produced from Daekwallyoung was the highest, followed by the order of Bosung, atlantic was the highest in dry matter content, followed by the order of NS1, NS2, Superior and Gemchip. Degrees of change in glucose content as affected by change of cultivated areas were different among varieties. Atlantic and NS1 showed less change of glucose content as compared with other varieties.

국내의 감자 재배지역(栽培地域)에 알맞은 가공용(加工用) 감자품종(品種) 선납(選拉) 및 재배지역(栽培地域)간 품질성(品質性)에 관한 기초자료를 얻고자 재배지역(栽培地域)별로 유망(有望) 가공용(加工用) 품종(品種) 및 계통(系統)들의 규격서(規格薯) 수량(收量) 및 품질(品質)에 미치는 영향에 대하여 시험을 실시한 결과를 요약하면 다음과 같다. 지역에 따른 평 균 총서(總薯) 수량(收量)을 보면 대관령(大關嶺) (3,051 Kg/10a), 강릉(江陵(2,863 Kg/10a), 보성(寶城) (2,844Kg/10a)의 순이었으며 평균(平均) 규격서(規格薯) 수량(收量)은 대관령9大關嶺) (2,351 Kg/10a), 강릉(江陵) (2, 278 Kg/10a), 보성(寶性) (2,246Kg/10a)의 순으로 높았다. 품종별(品種別) 수량(收量)은 각지역 모두 Gemehip이 가장 많았으며 이는 식용(食用)으로 사용하기에 유망하였다. 비중(比重)은 대관령(大關嶺)지역이 비교적 높았으며 품종간(品種間)에는 대서(大西)와 NS1이 높았고 Gemchlp은 낮았으며, 클루코스 함량(含量)은 NS1, 대서(大西), NS2, 수미(秀美) 및 Gemchip순으로 낮게 나타났고 chip color 역시 NS1, 대서(大西), NS2, Gemchip 수미(秀美)순으로 밝아 글루코스 함량과 밀접한 관계를 보여주었다. 제품수율(製品收率)은 각 지역 모두 대서(大닌西), NS1, 수미(秀美), NS2, Gemchip 순(順)으로 나타나 비중(比重)의 순서와 일치하였다. 이상과 같은 결과로 볼 때 대서(大西)와 NS1 품종(品種)이 칩 가공(加工)용 유망품종(有望品種)으로 판단되었다.
