우리나라 수박 주산단지에 심한 피해를 주고 있는 수박 탄저병에 대한 저항성 계통 육성을 위하여 국내·외에서 수집한 수박 유전자원의 병 저항성 검정으로 탄저병 저항성이 강한 ‘AU-Producer’를 선발하여 저항성 친으로, 고품질 계통인 ‘920533’을 반복친으로 1993년 인공교배를 하였으며 1994년 부터 1998년까지 BC4F1세대를 진전하였다. 1998년부터 2001년까지 원예적 특성 고정을 위해 6회 자가수분하여 세대를 진전하였으며 원예적 특
The incidence of Anthracnose causing severe damage to the foliage and fruit in watermelon has increased in some major watermelon producing areas in Korea. To develop anthracnose resistant line, ‘AU-Producer’ having resistant gene to anthracnose was selected from germplasm and crossed with high quality line ‘920533’. Following the initial cross, backrossing and disease screening were performed to select resistant lines that produced high yields with excellent quality fruit. As a results of these procedure, a mid maturing watermelon line, ‘Hangyeol’ with resistance to anthracnose (Colletotrichum orbiculare) race 1 and 3 was developed at the National Institute of Horticultural and Herbal Science, Rural Development Administration (RDA). It has red flesh and commonly produces fruit with clear stripes on skin between 5.3 to 10.1 kg. Average soluble solid contents are ranged from 9.8 to 11.8°Bx. The yield and quality of ‘Hangyeol’ is comparable to or better than those harvested from the popular commercial cultivars. The achievement of this experiment could contribute to provide the resistant parents in an anthracnose resistance breeding program in watermelon.
