Abstract

A new cultivar 'Picnic' originated from an artificial cross between 'Fuji' and 'Sansa' at National Institute of Horticultural & Herbal Science in 1994. The cultivar was preliminarily selected among the elite siblings for its high fruit quality in 2003. After regional adaptability tests in five districts for four subsequent years as 'Wonkyo Ga-34', it was ultimately selected in 2008. Optimum harvest time is late September. Mature fruit has mean weight of 233 g and is conic with light red skin on a greenish yellow ground and yellowish white flesh. The fruit contains a favorable total soluble solids content at $13.8^{\circ}Brix$ and titratable acidity at 0.43%, which results in gustatory harmony between sugars and acids. It is not resistant to bitter rot or Marssonina blotch. 'Picnic' exhibits a physiological cross compatibility with leading cultivars such as 'Fuji', 'Hongro' and 'Tsugaru'. Tree topology is semi-spreading with a weak growth habit.

신품종 '피크닉'은 국립원예특작과학원에서 1994년 '후지'에 '산사'를 인공교배하여 얻은 실생 중 유망한 계통을 2003년 예비선발하여 2004년부터 2008년까지 5년간 '원교 가-34호'로 군위 등 5개 지역에서 지역적응시험을 거쳐 2008년에 최종 선발한 품종이다. 과실의 적숙기는 9월 하순이고 과형은 원추형, 과피는 붉은색, 바탕색은 녹황색, 과육은 황백색이다. 과중은 평균 233g이며, 가용성고형물 함량은 $13.8^{\circ}Brix$, 산 함량은 0.43%로 당산미가 조화로워 식미가 우수하다. 탄저병에 약하고 갈색무늬병이 발생하기 쉽다. '피크닉'은 우리나라 주요 품종인 '후지', '홍로', '쓰가루' 품종과 교배친화성이 있다. 수세가 약하고, 수자는 반개장성이다.
