Abstract

Pear cultivar 'Sinhwa' (Pyrus pyrifolia var. culta Nakai) was originated from a cross between 'Niitaka' and Whasan' with the aims of improving the fruit quality and the traits of cultivation and of early maturing more than 'Whasan' cultivar at Pear Research Station of National Institute of Horticultural & Herbal Science, Rural Development Administration in 1995. 'Sinhwa' was preliminarily selected in 2004 and named in 2009. The tree shows vigorous growth habit and semi-spread characters like 'Niitaka'. Furthermore, it has a sufficient and well upkeep of the flower bud, so it can be more easily cultivated in orchards. In the flower characteristics, flowering time of 'Sinhwa' is $11^{th}$ April like as maternal parent 'Niitaka'. Also 'Sinhwa' has short of pollen grains, so it is need above two pollinizer cultivars. 'Sinhwa' is highly resistant to black leaf spot (Alternaria kikuchiana) and relatively strong to pear scab (Venturia nashicola) in field condition. The optimum harvest time is around Sep. $15^{th}$ in Naju, which is ahead of 'Whasan' about 10 days in the harvest period. The fruit shape is oblate and fruit skin color is yellowish-brown during harvesting time. The average weight of fruit is 627 g, and the soluble solids content is $13.0^{\circ}Brix$. The flesh is very soft and juicy, and renders good eating quality. Shelf life is about 30 days under the room temperature condition.

'신화' 품종은 농촌진흥청 국립원예특작과학원 배시험장에서 1995년에 '화산'의 뛰어난 맛과 부드러운 육질의 과실특성과 꽃눈의 분화 및 유지성이 좋은 '신고'의 재배적 특성을 가져 재배가 용이한 품종을 육성하기 위하여 '신고'에 '화산'을 교배하였다. 2004년에 1차 선발하고 2009년에 최종선발 하였다. '신화'의 수세는 강하고, 수자는 반개장성으로 수체특성은 종자친인 '신고'와 유사하다. 특히 꽃눈이 많고, 유지성도 좋아 수체관리가 용이하다. 화기 특성에 있어서 '신화'의 개화기는 4월 11일로 종자친인 '신고'와 비슷하다. 또한 꽃가루도 적어 수분수로 2가지 이상의 품종을 재배해야 한다. '신화'는 검은무늬병(Alternaria kikuchiana)에 포장 저항성을 나타내었고, 검은별무늬병(Venturia nashicola)에 비교적 강하다. 수확기는 나주에서 9월 15일 전후로 화산보다 10일 빨리 수확할 수 있다. 과형은 편원형이며 과피색은 수확기에 황갈색이다. 평균과중 627g이고, 당도는 $13.0^{\circ}Brix$이다. 육질은 부드럽고 과즙이 풍부하여 식미가 우수하다. 상온에서 30일 보관이 가능하다.
