Abstract

"Hongso" was originated from a cross between "Yoko" and "Hongro" in NIHHS, RDA, in 1989. "Hongso" was preliminarily selected in 2002 for its high fruit quality. After regional adaptability test at five sites from 2003 to 2006 as "Wonkyo Ga-30" it was finally selected in 2006. Optimum harvest time is early September which is similar to that of "Hongro". Fruit shape is globose conical and skin color is light red. Mean fruit weight is 295g and soluble solids content is 14.1oBrix. Fruits acidity is 0.34%, which is higher than that of "Hongro"(0.23%). It has a good taste for harmony of sugar and acidity. Storability is 3 weeks in room temperature. It is apt to russet on fruit skin. It is susceptible to Bitter rot. "Hongso" has a good cross compatibility with major cultivars such as "Fuji", "Hongro" and "Tsugaru". Tree habit is semi-spreading and tree vigor is weak. "Hongso" is high-density cultivation type cultivar, because it has a precocity, spur-type.

"홍소"는 국립원예특작과학원에서 1989년 "양광"에 "홍로"를 인공교배 하여 얻은 실생 중 유망한 계통을 2002년 1차 선발하여 2003년부터 2006년까지 4년간 '원교 가-30호'로 군위, 춘천 등 5개 지역에서 적응시험을 거쳐 2006년에 최종 선발하였다. 과실의 적숙기는 9월 상순으로 "홍로"와 비슷하다. 과형은 원원추형, 과피색은 선홍색, 바탕색은 녹황색, 과육색은 백색이다. 과실크기는 295 g으로 중 대과종이며 가용성고형물 함량은 $14.3^{\circ}Brix$, 산 함량은 0.34%로 "홍로"에 비해 산도가 높으며 당산미가 조화되어 식미가 우수하였다. 수자는 반개장성이고 수세는 약한 편이고, 조기결실성이며 새가지 생장이 적고 단과지형이나 액화 결실이 적어서 생력형 밀식재배 품종으로 유망하였다. 점무늬낙엽병에는 강하고 동녹 발생이 비교적 많은 편이며, 특히, 주요 재배품종과의 교배 친화성이 높다.
