Abstract

We bred a mulberry cultivar named Palcheong, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four places (Suwon, Kongju, Wanju, and Jinju) for seven years from 2007. This is belonging to (Morus Lhou(Ser.) Koidz.) selected among mulberry genetic resources preserved in Suwon. Its sex expression was hermaphrodite, which can be used for the production of seedling for fruit production by artificial crossing as pollen parent Palchung showed lower yielding in fruit productivity by 16% compared to control cultivar 'Chungil (Morus alba L.)' for five years. Although Palchung was higher in sugar content of mulberry fruits, it was bigger than that of 'Chungil'. 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 뽕나무 품종의 육성이 필요하다. 이에 따라 오디의 특성이 우수하고, 수량성도 비교적 높아 품종육성을 위한 교배용 화분친으로 이용할 수 있는 '팔청'을 선발 육성하였으며 이 품종의 육성 경위와 특성은 아래와 같다. 1. '07 ~ '13년까지 수원, 공주, 완주 및 진주 4개 지역에서 '청일'을 대조품종으로 하여 지역적응시험을 거쳤으며, 직무 육성신품종 심의회에서 화분친 교배용 및 오디 생산용으로 이용할 수 있는 품종으로 인정되었다. 2. '팔청'은 국립농업과학원 잠사양봉소재과 뽕나무 유전자원 포장(수원소재)에 보존되어 있는 계통 중 오디의 특성이 우수한 팔청시평을 선발 육성한 품종이다. 3. '팔청'은 노상형(Morus Loou(Ser.) Koidz.)에 속하는 자웅동주이며, 탈포기는 대조품종 '청일' 보다 빠르지만, 발아개엽기는 '청일'과 비슷한 중생종이다. 4. '팔청'의 잎의 크기는 크고, 잎모양은 잎끝이 뾰족한 피침형으로 짙은 녹색이며, 잎자루의 길이가 길다. 5. 오디는 식재후 3년차부터 결실하기 시작하였으며, 시험기간 결실 5년간의 평균수량은 '청일' 보다 16% 낮은 품종이다. 6. 오디 한 개의 무게인 단과중은 2.2 g으로 '청일' 품종 2.1g과 비슷한 소과형이며, 완숙된 오디의 색상은 검은색으로, 오디의 당도는 $15.4^{\circ}Brix$로 '청일' 오디 $14.6^{\circ}Brix$ 보다 높다.
