초록
내한성이 강하고 대립다수성이며 저장성이 우수한 다래 교잡종 육성을 위하여 국내 자생다래의 우량 선발 후보목의 클론검정을 통하여 선발된 대립 다수성 8개체와 내한성이 강하고 다수성인 교잡종 선발 2개체를 교배모수로 사용하여 화분수로 양다래 Matua와 인공 교배하여 얻어진 결과는 다음과 같다. 2년간의 인공교배 결과, 다래와 양다래의 교배조합에서 교배가 잘 이루어지는 개체와 교배가 전혀 되지 않는 개체가 있었으며, 다래와 양다래간의 교잡종은 양다래의 내한력과 교배 성공율 등을 고려할 경우 다래를 모수로 하는 것이 용이한 것으로 나타났다. 다래와 양다래의 종간교잡 결실율은 4.2~100%로 교배조합간 큰 변이를 보였는데, 이는 교배 모수의 효과가 큰 것으로 추정되었다. 인공교배된 과실의 무게와 종자수는 control보다 무게와 종자수가 훨씬 적게 나타났으며 충실종자율도 낮게 나타났다. 또한, 교배 종자의 발아율은 평균 19.2%로 control의 평균 38.7%보다 낮은 것으로 나타났다.
Abstract
Several endemic Actinidia arguta clones and two exotic A. deliciosa varieties were hybridized to develop cold tolerant hybrids that still bear large fruits. From nine artificial cross combinations made in 2 consecutive years more than 120 fruits were harvested. Significant variations were observed in fruit weight and fruit setting ratio among the different cross combinations. Some cross combinations failed to set any viable seeds even after repeated attempts made during the period. The fruit setting appeared to be strongly dependent on female parents. The number of seeds and percentage of filled seeds in fruits derived from interspecific cross were significantly less than those of control cross (A. arguta ´ A. arguta). The hybrid seeds showed the germination rate of 19.2%, which is lower than that of A. arguta with 38.7%. However, once germinated, mostly of the seedlings grew normally in the nursery. These will be used for the screening of the desirable traits such as cold hardiness, productivity and pest resistance.
