PURPOSE: A novel plant variety of high fertility xBrassicoraphanus with stabilized seed productivity is provided to improve seed productivity because all seeds are ripened without degeneration and to maintain uniformity.CONSTITUTION: A method for producing a novel plant variety of high fertility xBrassicoraphanus comprises the steps of: preparing 0.01 uM of mutagen NMU solution right before a culture of xBrassicoraphanus microspores treating the xBrassicoraphanus microspores with the NMU solution in a clean bench in the darkness to mutate the xBrassicoraphanus microspores culturing the mutated microspores and collecting seeds verifying seed productivity through artificial mating and verifying uniformity of the varieties using AFLP primer E-AAC/M-CAA to CGG.COPYRIGHT KIPO 2013[Reference numerals] (AA) O7BRop-814 BB1 (BB) O7BRop-815 BB4 (CC) O7BRop-811 BB12본 발명은 종자생산성이 안정화된 고임성 배무채 신품종 식물의 육종방법에 관한 것으로 돌연변이 유발물질 NMU를 0.01㎍/L 처리하여 배무채 종자를 돌연변이 처리하고 파종하여 채종하고 다시 파종후 실내에서 인공교배하여 종자생산성을 확인하고 이어서 AFLP primer를 이용하여 품종의 균일성을 확인하는 것을 특징으로 하는 배무채 신품종 식물의 육종방법을 개시한다.
