본 연구는 이전에 이배체와 삼배체를 교배하여 얻은 이수체 사과 나무의 생장과 과실 특성을 알아보고자 수행하였다. 이수체 사과나무의 화분발아율, 영양생장, 과실의 특징을 조사하였다. 그 결과, 이수체 사과 나무 간의 화분발아율의 차이가 크고, 모든 이수체 사과 나무의 화분 발아율이 이배체 '홍로' (82.4%) 보다 낮은 것으로 나타났다. 이수체 사과 나무 과실의 평균 크기와 중량은 이배체 '홍로'보다 작고 가벼운 것으로 나타났다. 또한 이수체 사과 나무 과실의 길이와 너비에 의해 이수체 JF3942빼고 다른 이수체 과실의 외형이 조금 납작했다. 거의 모든 이수체 사과 나무 과일의 당 함량은 이배체 '홍로' 보다 높았다. 본 실험에서 얻은 이수체 사과의 산 함량은 이전에 대부분의 연구자의 이배체 사과 결과와 완전히 달랐다. 이수체 사과의 시트르산하고 타르타르산 함량은 사과산 함량보다 더 높은 것으로 나타났다. 이수체 사과 나무의 수고와 폭은 이배체 '홍로'보다 짧았다. 대부분 이수체 사과 나무의 수고는 폭보다 길지만 네 나무는 반대로 나타났다. 잎의 길이와 너비에 의해 이수체 사과 나무 잎의 크기가 이배체 '홍로'보다 작았다. 이수체 사과 나무는 이배체보다 잘 자라지 않는 것으로 나타났다.

This study was conducted to observe some characteristics of aneuploid trees obtained from the crosses between diploid and triploid in the first experiment. The results showed that the difference among the percentage of aneuploid's pollen grain germination was large, and all of them were lower than that of diploid 'Hongro' (82.4%). The average weight and size of each aneuploid's fruit was far lighter and smaller than that of diploid 'Hongro'. According to the width and length, all of the fruits shape was flat or short-globose conical shape except for JF3942. Almost all the aneuploid had higher sugar content than 'Hongro', nearly half of aneuploid fruits were firmer than that of diploid 'Hongro'. As for the acid contents of aneuploid fruits, the results were greatly different from those of previous studies on diploid apples, in present study the citric acid and tartaric acid contents were more than the malic acid which are dominant acid in most cultivars of apples. Both the length and width of aneuploid tree were shorter than that of diploid 'Hongro'. Most aneuploid trees' height was longer than width, but there were 4 exceptions. The size of leaves was smaller than that of diploid 'Hongro' according to the length and width of leaves measured. In all, aneuploid's vegetative growth is not as vigorous as diploid.

문제 정의
12 aneuploid trees which began to flower after 6 year sowing were selected to observe their growth characteristics including vegetative growth and fruit in this study. The purpose of this is to find theirs special potential which is worthy of using as breeding materials.
가설 설정
In the last paper (Zhang and Park, 2009), 181 aneuploid apple trees were obtained through crosses between diploid and triploid. As a result of meiotic irregularity, in this study we hypothesized that unreduced gametes and gametes with aberrant chromosome or some reduplicate segment may lead to special characteristics of their progenies. 12 aneuploid trees which began to flower after 6 year sowing were selected to observe their growth characteristics including vegetative growth and fruit in this study.

The materials were the 12 aneuploids obtained from the progenies of crosses between diploid and triploid in last paper and a cultivar ‘Hongro’ (2x) as control. All of the trees were in the farm of Kangwon National University, Chuncheon, Korea. The flowers were picked from each aneuploid tree before the cluster dehisced pollen in April 28th, 2008.

성능/효과
Lack of vigor of the trees inevitablely result from the irregularities in germ-cell formation in the parents, and the aneuploid chromosome constitution of their offspring (Crane and Lawrenece, 1933). So conclusion was made that in this study the vegetative growth of 12 aneuploid trees were not vigorous probably because the weight of seeds which developed to these aneuploid trees was light. Their weight distribution of the seeds mostly ranged from 20 to 35 mg was showed in the last paper (Zhang and Park, 2009).
, 2007). Their results indicated the characteristic difference of whole progenies obtained from each cross, furthermore, they did not make sure those obtained from each cross were all aneuploid or not, or how much percentage of aneuploid among of them. The seedlings obtained must contain some diploid seedlings.

The homeostasis of their expression, along with the corresponding enzyme activity, leads to the difference in fruit acidity between low and high acid genotypes. The data presented here only described three kinds of acids content during the first one year growth, further understanding of the kinds and content of the organic acid in next few years would be needed. In particular, the proportion of various acids remains to be studied and quantified.
