국문 초록

딸기는 근연교배가 다른 작물에 비해 상대적으로 약한 타 식성 작물이다. 딸기의 대다수 품종 육성방법은 품종간 교잡으로 부터 우수한 개체를 선발하는 선발육종을 기본으로 하여 왔다. 그러나 계통 육성방법도 우수한 유전자를 집적하기 위한 방법으로 많이 이용되어 왔었다. 따라서 딸기의 육종효율을 증진시키기 위해 자식 또는 근계교배를 통하여 조합능력이 높은 유전자형을 가진 근교계를 만들고자 형질이 우수한 품종을 대상으로 자식을 실시하였다.

영문 초록

Strawberry is an out-crossed crop that is relatively sensitive to inbreeding, and as a result, most of breeding programmes in strawberry have been based on selection breeding where elite parents are selected from intercrossing. Also, pedigree breeding has been successfully employed in a number of instances to concentrate genes of interest. Therefore, in order to obtain inbred line having the genotype of excellent combining ability by selfing and incrossing to improve breeding efficiency of strawberry, elite varieties were self-pollinated. From the selfing line of Benihoppe cultivar, we selected Wongyo 3111 having excellent horticultural traits such as plant vigor, sugar content and fruit hardness among these progenies. Wongyo 3111 shows erect plant type, vigorous growth habit, early flower bud differentiation with 16~17 flowers per cluster. Fruits of Wongyo 3111 are conical type having a bright red skin color, and 17.2 g in an average weight. Also that have a relatively more high sugar/acid ratio and firmness than check cultivars as sugar content of 11.3oBx, acidity of 0.50% and firmness of 21.7 g/mm^2. But although yield of Wongyo 3111 is not significantly different from check cultivars, its marketable yield is remarkably lower than that of check cultivars because of poor fruit-setting under low temperature. Disease and pest reactions of Wongyo 3111 are more sensitive to powery mildew, anthracnose and spotted spider mites than check cultivars. Therefore, Wongyo 3111 is suitable for intermediate parent line better than as a cultivation cultivar.
