Abstract

We bred new mulberry cultivar through local adaptability test, which was registered as a new cultivar for fruit production. Local adaptability test had been carried out at three places(Suwon, Chuncheon and Jinju) for four years since 2003. This is tetraploidy variety belonging to (Morus Lhou(Ser.) Koidz.) made by colchicine treatment on growing point of winter buds. Daejappong was high yielding in productivity by 3% compared to control cultivar "Chungilppong" for two years.The sugar contents of Daejappong was higher than that of control cultivar 'Chungilppong(Morus alba L.)'. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

주로 누에사육을 위한 사료 생산용으로 이용되던 뽕나무의 용도가 다양화 되면서, 부산물로 이용되어 온 오디가 새로운 소득작목으로 정착되어 가고 있다. 이에 따라 오디 생산에 적합한 뽕 품종에 대한 수요가 늘어나고 있어, 새로운 오디용 뽕품종으로 "대자뽕"을 육성하였으며 이 품종의 육성 경위와 특성은 아래와 같다. 1. '03-'06년까지 수원, 춘천 및 진주 3개 지역에서 청일뽕을 대조품종으로 하여 지역적응시험을 거쳤으며, 직무육성신품종 심의회에서 오디 생산용으로 우수한 품종임이 인정되어 품종으로 등록하였다. 2. 대자뽕은 농업과학원 잠사양봉소재과 수원 유전자원 포장에 보존되어 있는 2배성 국상 20호 계통에 콜히친을 처리하여 만든 염색체수가 2n = 56인 4배체 품종이다. 3. 대자뽕은 노상형(Morus Lhou(Ser.) Koidz)에 속하는 암나무이며, 발아개엽기는 청일뽕과 비슷한 직립성의 중생종이다. 4. 잎의 크기는 대형으로 두꺼우며, 잎모양은 타원형이다. 5. 오디는 식재 후 3년차부터 결실하기 시작하였으며, 10a 당 연간수량은 결실 1년차에는 청일뽕보다 33% 낮았으나, 2년차에는 17% 증수되어 2년 평균 3% 증수되는 다수성 품종으로 결실성이 우수한 품종이다. 6. 오디의 단과중은 4.5 g으로 대과형이며, 완숙된 오디의 색상은 적자색으로, 오디의 당도는 청일뽕보다 높은 고품질이다.
