Abstract

To assess the dormancy associated weedy risk of the F1 hybrid generated by hybridization between Brassica juncea (maternal) and Brassica napus (paternal), seed germination, dormancy and longevity were examined sequentially after seed harvest. The F1 hybrids exhibited the intermediate characteristics of their parents in seed germination and dormancy with relatively high dormancy rate of 41.1%. In summer, F1 hybrid seeds buried in the 3 cm soil exhibited greater viability (52.4%) than those in the soil surface with greater seed longevity (74.6%) than its maternal (63.3%) and paternal (33.7%) parents at 100 days of over-summering in soil. In winter, F1 seeds buried in the soil surface were more viable than those in the 3 cm soil with greater seed longevity (83.5%) than its maternal (39.0%) and paternal (71.7%) parents at 100 days of over-wintering in soil. Therefore, it is concluded that F1 hybrid resulted from gene flow from OSR to mustard has high seed dormancy and longevity during summer and winter, suggesting its weedy risk potential. Further studies are required to examine the reproductivity and fitness cost of F1 hybrid to make a clearer conclusion of its weedy risk.

본 연구는 유채의 화분이동으로 근연종 갓과의 교잡을 통해 형성된 교잡종의 발아휴면특성과 월하 및 월동성을 평가하여 교잡종의 잡초화 가능성을 예측하고자 본 연구를 수행하였다. 교잡종은 부본인 유채와 모본인 갓에 비해 전반적인 발아특성이 갓에 근접한 중간적인 특성을 보여주었으며, 휴면성도 41.1%로 갓에 근접한 높은 휴면성을 보여주었다. 수확 직후 종자를 토양에 매립하여 월하특성을 평가한 결과 표토보다는 3 cm 토심에서 월등히 높은 월하특성을 보여주었으며, 월하기간과 상관없이 3 cm 토심조건에서 부본인 유채에 비해 매우 높고 모본인 갓에 비해 약간 높은 월하특성을 보여주었다. 반면 종자의 월동특성은 월하특성과 반대로 표토조건에서 교잡종이 부모종보다 높은 월동성을 가지는 것으로 확인되었다. 따라서 유채-갓 교잡종은 휴면성이 비교적 높고 월하 및 월동성이 높아 잡초화 가능성이 있음을 시사한다. 유채-갓 교잡종의 보다 명확한 잡초화 가능성 평가를 위해서는 교잡종의 종자생산 가능성 및 자연 생태계 적응성 여부에 대한 추가적인 연구가 필요하다.
