초록

원예연구소(園藝硏究所) 과수육종과(果樹育種科)에서 '78년에 '신흥(新興)'과 '풍수(豊水)'를 교배(交配)하여 얻은 계통(系統) 중 78-29-3이 중생(中生)이면서 감미(甘味)가 높아 '91년에 1차 선발(選拔)되었다. '92년부터 '95년까지 4년간 '원교(園交) 나-13호'로 9개 지역에서 지역적응시험(地域適應試驗)을 실시한 결과, 그 특성이 우수하여 '95년에 최종(最終) 선발(選拔)하여 '신일(新一)'로 명명(命名)하였다. 수세(樹勢)는 중(中), 수자(樹姿)는 반개장형(半開張形)이며 단과지(短果枝) 형성(形成)이 잘되어 풍산성이고 배나무잎검은점병과 흑반병(黑斑病)에 강하여 재배가 용이하다. 만개기(滿開期)는 '95년 4월 27일로 장십랑(長十郞)과 같고 꽃가루가 풍부하며 '조생황금(早生黃金)' 이외의 주요(主要) 재배품종(栽培品種)과 교배친화성(交配親和性)으로 수분수(授粉樹) 품종으로도 좋다. 숙기(熟期)는 9월 25일로 풍수와 비슷하며 추석(秋夕)이 9월 하순(下旬)인 해에 유리하다. 과형(果形)은 원형이며 과피색(果皮色)은 선명한 담황갈색으로 외관(外觀)이 수려하고 과중(果重)은 370g 내외로 장십랑 정도이며 당도(糖度)는 $14.0^{\circ}Bx$로 장십랑보다 높다. 육질(肉質)은 유연다즙(柔軟多汁)하고 석세포(石細胞)가 적어 장십랑과 대비되며 과육색(果肉色)은 투명한 백색(白色)으로 아름답다.

'Shinil' pear cultivar (Pyrus pyrifolia Nakai) which was originated in a cross between 'Shinko' (non-patented, released in 1941) and 'Hosui' (non-patented, released in 1972) in 1978 was released as a middle season harvest variety. Its usual picking time coincided with 'Chuseok' season which is one of the most famous national holiday in Korea. The fruit showed high soluble solids content and good appearance. The cultivar was preliminarily selected in 1991, and its regional adaptability was evaluated in the name of 'Wonkyo Na-13' at 9 sites for four years from 1992, and finally selected and named in 1995. 'Shinil' is medium in tree vigor like 'Hosui' and spreading in tree habit as 'Niitaka', a leading cultivar in Korea, and consistently very productive. It has high resistance to black rot caused by Alternaria kikuchiana and pear necrotic spot caused by pear necrotic spot virus. Its full bloom is one day earlier than that of 'Niitaka' cultivar and harvest time is September 25 at Suwon area which is 3 days later than that of 'Hosui'. Fruit is round in shape with a deep medium stalk cavity and medium calyx basin and has attractive light yellow brown skin color. The fruit weight ranges between 300 and 400 g, which is similar to 'Chojuro', 'Shinko', and 'Hosui'. Soluble solid content is approximately at the level of 13-14 Brix, which is higher than that of 'Chojuro'. The flesh is cream-white, very juicy, and light grit with soft and fine texture.
