영문 초록

This study was conducted to explore the possibilities for the maintenance and multiplication of parental lines in rape(Brassica napus L.) heterosis breeding. Growth regulators influencing organogenesis were investigated in stem culture grown on a synthetic nutrient medium. Naphthaleneacetic acid(NAA), Indoleacetic acid (IAA) induced root, where as 2.4-Di chlorophenoxyacetic acid(2,4-D) didn’t induce. The whole plants were not induced when auxins such as NAA, IAA and 2.4-D, and cytokins such as benzyladenin(BA) and Kinetin were added individually. When NAA(0.5-2.0 ㎎/ℓ) was employed in conjunction with BA and Kinetin(1.0-2.5 ㎎/ℓ),whole plant was obtaind. The whole plant induction percentage were 56% and 11% in NAA 1.0 ㎎/ℓ+ BA 2.0 ㎎/ℓ and NAA 0.5㎎/ℓ+ Kinetin 2.0㎎/ℓ, respectively. Majority of whole plant were induced between 3-4 weeks after culture initiated.
