Abstract
신품종 '여홍'은 국립원예특작과학원에서 1993년 '홍옥'에 '후지'를 인공교배하였고, 2002년에 고품질 과실의 우량 계통에서 예비선발하였다. 4년간 5개 지역에서 지역적응시험을 거쳐 '원교 가-31호'로 2007년에 최종 선발하였다. 과실의 적숙기는 9월 하순이고 과형은 편원형, 과피는 홍색, 바탕은 녹황색, 과육은 황백색이다. 과중은 평균 278g이며, 가용성고형물 함량은 <TEX>$14.3^{\circ}Brix$</TEX>, 산 함량은 0.4%로 당산미가 조화로와 식미가 우수하였다. 상온저장력은 3주 정도이며, 탄저병에 이병성이다. 신품종 '여홍'은 '홍로'와 '쓰가루' 품종에는 교배친화성이 있으나, 자방친인 '후지'와는 교배친화성이 없었고, 수세는 약한 편이다. A new cultivar 'Yeohong' was originated from an artificial cross between 'Jonathan' and 'Fuji' carried out at National Institute of Horticultural & Herbal Science in 1993. The cultivar was preliminarily selected among the elite siblings for its high fruit quality in 2002. After regional adaptability test at five districts for subsequent four years as 'Wonkyo Ga-31', it was finally selected in 2007. 'Yeohong' is characterized by the following. Optimum harvest time is late September. Shape of mature fruit at 278 g on mean weight is oblate a light red skin on a greenish yellow ground and yellowish white flesh. The fruit contains favorable total soluble solids at <TEX>$14.3^{\circ}Brix$</TEX> and titratable acidity at 0.4%, which results in a gustatory harmony between sugars and acids. Safe storage period for the fruit is 3 weeks at room temperature. It is not resistant to Bitter rot. 'Yeohong' also reveals a physiological cross compatibility with leading cultivars such as 'Hongro' and 'Tsugaru', but a physiological cross incompatibility with 'Fuji'. It has weak growth habit.
