들깨 품종의 생태형과 성숙군의 분류

Classification of Ecotypical and Maturing Groups of Perilla varieties

우리나라 들깨 재래종 136과 일본품종 4합계 140품종에 대하여 개화 및 결실에 관한 제특성의 차이를 검토하며 품종의 생태형과 성숙군을 분류하고 이들 특성과 생태형, 성숙군간의 관계를 요약하면 다음과 같다. 1. 생태형의 분류는 개화일수의 단, 중, 장(I.II.III)에 결실일수의 단장(a,b)을 상호조합하여 Ia, Ib, IIa, IIb, IIIa, IIIb의 6형으로 나눈바 우리나라 재래종은 IIa, IIb 및 III형에 일본품종은 IIa, IIb에 각각 많이 속해 있었다. 2. 성숙군의 분류는 생육일수의 장, 단에 따라 조생 I에서 만생 III까지 3성숙군으로 나눈바 우리나라 재래종은 II군 및 III군에 일본품종은 I군과 II군에 각각 많이 속해 있었다. 3. 생태형과 성순군 사이에는 고도의 정(+)의 상관관계(0.685)를 볼 수 있었고 생태형은 개화일수, 생육일수와 성숙군은 개화일수, 결실일수 및 생육일수의 상호 유의적인 상관을 인정할 수 있었으나 우리나라 재래품종은 성숙군수가 많지 않지만 생태형 종수가 많다는 것은 도별로 환경조건과 재배방식간에 어떤 관계가 존재하는 것 같다.

In order to classify the ecotypical and maturing groups 136 Korean local and 4 Japanese Perilla varieties were sown at Suwon on May 20, 1972, and investigations were made on days to flowering, days to maturing and growth duration. Results obtained were summarized as follows: 1. Ecotype was classified from 6 groups with combination of the long and short duration from sowing to flowering and maturing period. The classified symbols of groups were Ia, Ib, IIa, IIIa, and IIIb. I: long duration. to flowering II: medium duration to flowering III: short duration to flowering a: long duration to maturing b: short duration to maturing Korean local varieties were distributed 3 ecotypes of IIa, IIb and IIIa, however, Japanese varieties did 2 ecotypes of IIa and IIb, respectively. 2. Maturing group was classified from 3 groups with long (I), medium (II), and short (III) growth durations. Korean local varieties belong to II and III groups but Japanese varieties belong to I and II groups, respectively. 3. Three were highly significant positive correlation (0.685) between ecotypical and maturing group. Ecotype was more related with days to flowering and growth duration, however, maturing group was related with days to flowering, days for maturing, and growth duration. Korean local varieties, more distributed into ecotype than maturing group, were attributed to differences of environmental conditions and cultural practices at different provinces.
