金周玹,嚴聖均 慶尙大學校 1989 論文集 Vol.28 No.2

여주의 果重을 目標로 早期에 選擇할 수 있는 效果的인 方法을 檢討키 위하여 果實特性面에서 相異한 4個育成系統을 材料로 이들을 二面交雜하여 兩親과 F1組合들을 pot에 심어 溫室內에 栽値하여 相觀및 遺傳分析을 試圖하였다. 相觀分析에서 調査된 形質은 子房長등 15個 形質이었고, 이중 種子 및 子房關聯形質인 種子길이, 種子幅,種子重,種子數,子房長,種子幅,種子重,果梗長, 8個形質에 대해서는 二面交雜分析을 하였다. 收量과 相關이 매우 높은 形質들은 果長, 果重, 子房長, 果梗長(花梗長), 種子幅등 이었으며, 이들 形質들은 相互間에도 높은 相關이 있었다. 種子數를 除外한 大部分의 形質들이 遺傳子의 優性 果보다 相加的效果가 컸으며, 特히 子房長과 果梗長, ,種子幅은 매우 높은 相加的遺傳子作用에 의해 支配되, 遺傳力도 매우 높았다. With a purpose to increase the effect of selection in bitter gourd(Momordica charantia L.), four inbred lines were crossed each other for a diallel cross set, and grown in the green house. The characters investigated were fruit length, fruit width, fruit weight, number of fruits, thickness of fruit flesh, days to maturity (from flowering) seed length, and yield. Correlation coefficient analysis revealed that six characters, i.e., fruit weight, fruit length, ovary length, peduncle length, seed width, and yield showed highly positive correaltions each other. Among 15 characters, eight characters, such as ovary length, ovary width, ovary weight, seed length, seed width, seed weight, number of seeds, and peduncle length, showed partial dominance in Vr-Wr graphical analysis, but they showed different degree of dominance. Overy length, seed length, seed width, and seed weight were controlled by additive rather than dominant effect of genes, and they had very high heritabilities in both broad and narrow sense, while in ovary weight, ovary width, and peduncle length, additive effect of genes was similar to dominant effect. Number of seed per fruit was governed by dominant rather than additive effect of genes. Heritabilities(h²n) in the narrow sense were low or moderate for number of seed, ovary width, and ovary weight, and that of peduncle length was high.

고랭지에서 척박한 모재토를 성토한 포장에서 감자를 재배한 후 후작으로 호밀을 재배하는 작부체계 하에서 대조구, 화학성개량구, 제오라이트구 등 3개 처리를 두고 감자 파종 전 성장하고 있는 호밀을 경운, 매몰하여 감자를 1999년부터 2년간 재배하면서 몇 가지 토양개량 처리한 것을 조사 분석한 결과는 다음과 같다. 1. 성토재료용 모재토는 양질사토로서 유기물과 인산함량 등 이화학성이 매우 낮은 척박토이었다. 2. 감자의 지상부 생육은 대조구에 비하여 제오라이트구와 화학성개량구가 좋았으며 감자수량도 2.1~4.5% 증수되었다. 3. 감자 수확 후 토양이화학성은 시험 전에 비해 점차 증가하였으며 호맥재배로 토양 유기물과 인산함량 증가가 컸다. 4. 호맥은 감자 파종 1주일 전에 경운, 매몰하였으며 그 효과는 토양 중 유기물함량 0.5~3.5g/㎏정도 지력 증진효과가 있었다. This study was conducted to investigate the changes of crop growth and soil properties under potato-rye cropping system in highland mounding-soil. Experimental plots were designed with control, chemical improvement and zeolite+chemical improvement plot during 1999 to 2000year. Mounding-soil were low in the contents of soil chemical properties that organic matter contents etc., and that soil texture was loamy sand soil. The growth and yield of potato in the chemical improvement and zeolite plots were higher than that of control plot by 2.1~4.5%. After harvesting, the contents of soil chemical properties increased than those of experiment before. Increasing ratios of soil organic matter and phosphate contents were higher than other soil properties by rye cultivation. Rye residues were buried and tilled before potato planting at 1 week. Rye residues burying deep under the ground increased by 0.5~3.5g/㎏ to soil organic matter contents.

우수한 당근 품종육성을 위한 기초자료를 얻고자, 육성 계통들 중에서 선발된 재료를 사용하여 어떤 형질이 根重에 크게 영향하는가를 확인코자 하였다. 2년에 걸쳐 봄, 가을 재배작형에 대해 시험한 결과를 상관 및 경로계수 분석을 통하여 根重에 미치는 여러 형질의 직ㆍ간접효과를 조사한 바, 봄, 가을, 재배 년도의 구분 없이 葉重과 全重의 직접효과가 매우 컸고, 나머지 형질들의 직접효과는 크지 않았다. 직접효과에 있어서도 全重은 정의 방향, 葉重은 부의 방향으로 달리 영향하는 것으로 나타났다. 나머지 형질들 중 葉重, 根首徑, 根徑, 葉長 등은 根重에 대한 직접효과는 크지 않았지만 全重을 통한 간접적 효과가 인정되었다. This study was conducted to clarify the direct and indirect effects of major morphological characters affecting root weight of carrot. The field experiment was carried out two times in 1991 and 1995. Root weight, number of leaf, leaf length, crown diameter, root diameter, root length, branch root, root cracking, bolting, uniformity, root-tail form, root shape, leaf weight, total weight, smoothness of root skin and hypertrophy of root were investigated. Major characters which had a direct effect on root weight were leaf weight and total weight. Total weight contributed positively towards root weight, but leaf weight had a negative effect. Number of leaves, leaf length, crown diameter, and root diameter did not have a direct influence on root weight, but they affected indirectly on root weight through increasing of total weight.

당근 육종에 있어서 계통선발 평점에 관련된 主要 形質들의 經路係數 分析

표재수,이상우,김주현 경상대학교 농업생명과학연구원 2002 농업생명과학연구 Vol.36 No.2

당근 육종 과정 중 유망계통으로 선발되는 기준인 선발 평점이 주로 어떤 형질들에 의해 크게 영향받는가를 알고자 하였다. 5년에 걸쳐 봄 재배작형으로 시험한 자료를 가지고 상관 및 경로계수 분석을 통하여 선발평점에 미치는 여러 형질들의 직ㆍ간접효과를 조사한 바, 각 형질의 선발 평점에 대한 기여도는 년차에 따라 달랐다. 따라서 가장 큰 직접효과나 간접효과를 나타내는 형질은 매년 변하였다. 그러나 거의 항상 비교적 높은 직ㆍ간접 효과를 나타내는 형질은 찾을 수 있었는데 이는 근중과 고환성이었다. 이들 다음으로는 엽장과 수경등이었다. 반면 엽수, 지근, 근형, 근피특성 등은 직ㆍ간접효과가 가장 작았다. This study was conducted to clarify the direct and indirect effects of major morphological characters affecting selection score of carrot. The field experiment was carried out five times from 1991 to 1995. Root weight, number of leaf, leaf length, crown diameter, root diameter, root length, branch root, root cracking, bolting, uniformity, root-tail form, root shape, leaf weight, total weight, smoothness of root skin, hypertrophy of root and selection score were investigated. No character constantly showed the highest direct/indirect effect. Therefore the character showed the highest direct/indirect effect changed year to year. But it was possible to find out which characters were more important, or not. In frequency of high-ranked direct/indirect effect, two characters, root weight and root-tail form, were considered more important. The next characters were leaf length and crown diameter. The lowest were leaf number, branch root, smooth of root skin, and root shape.

This experiment was conducted to obtain some basic imformation for korean native oriental melon breeding. Genetic variability, heritability, and correlation on 13 characters were analyzed. The results are summarized as follows; 1. Among 13 characters, plant height and length of lateral shoot showed high level of GCV(110-362%) and ECV(89-101%). The rest characters showed low level of GCV(7-21%) and ECV(0.16-9%). 2. Heritabilities of 13 characters investigated were high as over 50%. Especially those of hypocotyl length, 100-seed weigth and seed width were very high (> 95%). 3. High level correlation values were observed among seed characters and seedling characters. 4. Plant characters of early growth stage, except leaf stalk length, were not related with characters of seed or seedling 5. In early plant growth stage, plant height and length of lateral shoot were correlated positively with number of node, number of lateral shoot, leaf length and leaf width.

Inheritance and Characteristics of a New Dwarf Mutant in Lettuce

Zhoo-Hyeon Kim 한국원예학회 2004 Horticulture, Environment, and Biotechnology Vol.45 No.6

One spontaneous dwarf mutant of lettuce was found in the segregating population derived from the cross 86-197-2-1-4 × Prizehead. This mutant has shrunken, dark red cotyledons and very short hypocotyls. The stems and leaves were very soft and weak. The leaf size was smaller than 1/2 of that of the normal plant, and the flower stem was much shorter. The mutant was crossed with normal lettuce lines of 87-25M-2M and D24. The F₁ plants were normal, and the F₂ populations segregated in a 3:1 of normal and dwarf, showing that this dwarf characteristic is controlled by a single recessive gene. The results from the F₃ families confirmed the F₂ results, and the gene was named dwarf-5. The correlations of dwarf character between true second leaf length and width, number of internodes on cauline stem, three internodes length, the largest leaf length, width, and area were investigated. Dwarfing type plants could be found easily by selecting the plants having short second leaf at seedling stage.
