방울토마토에서 단주계통법(Single Seed Descent)으로 공시개체수에 따른 계통선발의 효과를 비교하고자 ‘미니캐롤’과 ‘다다기’를 교잡하여 개체수가 30, 60, 120, 210주로 다르게 처리하였다. 초기세대 G₂와 후기세대 G₅를 비교한 결과 각 세대별 평균 가용성고형물 함량은 후기 세대에서 높았으나 과중은 감소하는 경향이었다. 또한 세대가 진전될수록 고당도 개체의 출현율이 증가하였고, 가용성고형물 함량의 최고치가 8.3～8.8°Brix의 범위로 교배친보다 높아 보다 우수한 고당도 개체의 선발이 가능할 것으로 생각되었다. 처리구별 선발된 계통에 대한 특성을 비교한 결과, 개체수를 30으로 한 처리구에서 과중이 작고 수량성이 비교적 낮아 선발효과가 낮게 나타났으며 60, 120, 210개체의 처리구간 선발효과는 대등한 것으로 보였다.

This study was conducted to investigate the effects of the population sizes on the line selection by single seed descent (SSD) breeding method in cherry tomato. The seed were obtained from crossing for ‘Mini Carol’ and ‘Dadagi’. The population groups were separated for 30, 60, 120, and 210 seeds group. Soluble solids contents were higher and fruit weights were more decreased in late generation (G5) than in early generation (G2). In addition, the appearance ratio of the plants with sweet fruits was increased with the generations advanced and soluble solid was ranged from 8.3 to 8.8 °Brix. By these results, it is expected to be able to select the lines with sweeter fruits than those of parents. The selection effect was low in the population with 30 plants and it was same in three popuiations 60, 120 and 210.
