Blueberry (Vaccinium spp.) is a bush that grows well at special cultural environments such as acid soil, high organic matter content, and a good drainage and aeration compared to other general crops. Blueberries are well known to contain high amounts of anthocyanins and phenolic compounds, resulting...

블루베리란 무엇인가? | 블루베리(Vaccinium spp.)는 히말라야, 뉴기니, 남아프리카의 안데안까지 세계적으로 자생하는 진달래과(Ericaceae)의 관목식물이며, 진달래과 식물의 기원은 남아메리카로 추정되고 150 ~ 450종이 분포하고 있는 것으로 알려져 있다(Retamales and Hancock 2012). 진달래과에는 Cyanococcus (blueberries)속, Oxycoccus (cranberries)속, Vitis-Idaea (lingonberry)속, Myrtillus (bilberry, whortleberry)속으로 분류되며, 대다수의 종들은 다배수성(polyploidy)이며 복수의 염색체들로 이루어져 있다. | |
블루베리의 수량성, 과실품질, 수세 등은 무엇에 영향을 받는가 | 따라서 블루베리 육종가들과 연구자들은 보다 효율적인 블루베리 신품종 개발과 우수한 품질의 과실생산을 목표로 연구 중이다. 블루베리는 현재 서로 다른 여러 가지 종들이 다양한 기후대에서 널리 재배되고 있으며, 재배기간의 온도, 토성, 강수량 등 환경요인과 생물학적 및 비생물학적 스트레스에 의하여 수량성, 과실품질, 수세 등이 크게 영향을 받게 된다. 그러므로 이러한 다양한 환경 조건에서 보다 안정적인 수량 확보와 기능성이 높은 품종 선발과 재배기술 향상에 대한 연구가 필요하다. | |
블루베리에서 기능성이 높은 품종 선발과 재배기술 향상을 위해서는 어떤 전략이 필요한가? | 이러한 목표를 달성하기 위해서는 블루베리 유전체와 생리적 특성의 이해를 기반으로 내한성, 저온요구도, 내서성, 내병성, 내충성이 강한 계통에 대한 유전체 해석 및 유전체 활용 전략이 필요하다. 또한 소비자들을 위해 서는 높은 함량의 안토시아닌과 식이섬유, 식미도 증진, 보다 저렴한 가격의 과실 생산이 가능하도록 하여야 하며, 육종가에게는 위와 같은 다양한 유전적 정보들을 제공할 필요성이 있다(Lobos and Hancock 2015; Mudd et al. 2013). |
