紫蘇品種 育成의 보다 效率的 選拔에 關한 基礎資料를 얻기 위하여 日本 導入種 및 國內 蒐集種 16品種을 供試하여 主要型質을 調査한 後 各 形質에 대한 遺傳力과 그들 相互間의 表現型相關 및 遺傳相關, 그리고 經路係數 分析을 通하여 收量構成 形質들의 收量에 대한 寄與度를 推定하였던 바 結果를 要約하면 다음과 같다. 1. 莖長과 穗長는 遺傳力도 높고 收量과 表現型 및 遺傳相關도 높아 이들을 通한 收量增大 效果가 보다 效率的이었다. 2. 收量과 收量構成形質의 經路係數 分析結果 穗長과 葉長 및 分枝數가 가장 크게 收量에 寄與하였다 In order to investigate the gene action of the quantitative characters in Perilla Frutescens which would be needed to improve selection efficiency for breeding high yielding genotype, sixteen varieties of Perilla Frutescens collected from Korea and Japan were grown and variations of several important characters were observed. Heritabilities of observed characters, phenotypic and genotypic correlations among the characters, and direct effects of yield components on grain yield through path coefficient analysis were estimated. Stem length, panicle length and leaf width showed not only high heritability but also highly significantly positive phenotypic and genotypic correlation with yield, and hence it was desirable to select plants with longer stem and greater number of branches in main stem to raise yield of perilla Frutescens. In addtion, these characters were proved to be the most influencial variables on the variability of yield by path coefficient analysis. Since these characters showed the greater heritabilities, selection of plants with greater number of branches in main stem would be more ficient for breeding high yielding genotype.

벼 乾畓直播와 灌水時期 및 移秧의 時期를 比較試驗했던바 그 結果를 要約하면 아래와 같다. 1. 發芽는 水稻, 陸稻모두 良好하였다. 2. 稈長, 穗長, 穗數는 直播區와 標準 移秧間에는 大差가 없고 直播區와 移秧間, 標準移秧과 移秧間에는 아주 심한 差가 있었다. 3. 倒伏은 水稻에 比해 陸稻가 아주 심했고 移秧區보다 直播區가 심한 경향이었다. 4. 病蟲害는 대체로 비슷하나 移秧보다 直播區가 다소 많고 6月 20日 灌水보다 7月 5日, 7月 20日 灌水가 적었다. 5. 玄米收量 結果 水稻, 陸稻 모두 移秧보다 直播(點播,條播)가 增收되었으며 條播보다는 點播가 좋은 成績을 보였다. The study was conducted to examine the effects of direct seeding on the growth and yield of rice on the dry paddy fields. Both lowland rice and upland rice showed the ighest germination ratio at the direct seeding plots. Culm length, panicle length and number of panicles per hill were highest at the direct seeding plots and the early transplanting plots. Ledging of upland rice and direct seeding plots were heavier than that of the lowland rice and transplantiog plots. Damage by disease and insect were highest to the plants at the direct seeding plots but that of the late irrigation of July 20 were lowest. Brown rice yield were the highest at the direct seeding of dibbling plots.
