續榮治,寺尾寬行,權炳善,梅崎輝尙 順天大學校 1994 論文集 Vol.13 No.1
紫蘇品種 有成의 보다 效率的인 選拔에 關한 基礎資料를 얻기 위하여 日本 導入種과 國內 蒐集種 16品種을 供試하여 主要 形質을 調査 했던 바 그 結果를 要約하면 다음과 같다. 1. 導入品種은 地方種에 比하여 莖長과 穗長이 길고 葉收量이 많았다. 2. 主要形質間의 相關은 모든 品種들이 莖長과 穗長間에 負의 相關을 나타냈고 莖長과 葉의 收量 및 種實重 間에는 높은 正의 相關을 나타냈으며 葉의 收量과 種實重 間에도 아주 높은 正의 有意相關을 나타냈다. 3. 導入品種은 地方種에 比해서 熱期도 빠르고 1次 收穫葉重 比率이 2次 收穫葉重 比率보다 높았다. 4. 遺傳力은 導入品種의 種實重만 낮고 그 外 모든 形質은 모든 品種에서 아주 높게 나타났다. □To obtain the basic information of more effective selection of variety of Perilla frutescens, this study tests 16 varieties of introduction breed from Japan and domestic breeds, examines their major characters and the results are summarized as follows. Stem length and panicle length of introduction breeds are longer than those of geo-ecotype. In the correlation of major characters, all varieties show negative correlation between stem length and panicle length, high positive correlation among stem length, leaf quantity and the weight of seed and extremely high positive correlation between leaf quantity and the weight of seed. The maturing time of introduction breed is faster than that of geo-ecotype and the first harvest ratio of the leaf is higher than that of the second ratio. In the heritability, the weight of seed of introduction breed is low and all other characters are high in all varieties.

In order to obtain basic informations on F_1 hybrids of rape which are suitable at the southern part of Japan, 10 hybrids were grown from Oct. 1990 to Jun. 1991 at faculty agriculture, Kyushu University, Fukuoka, 812, Japan, and the evaluations were conducted using heterosis which were comparison between the performance of F_1 and that of parental average and heterobeltiosis which were comparison between the performance of F_1 and that of better parent. All the 10 crosses showed high degree of heterosis and heterobeltiosis in plant height and the maximum increase over better parent was 21%. Ten crosses showed high degree of heterosis and a crosses showed greater ear length than better parents. In case of number of branches per plant, all 10 crosses exceeded the parents. In case of number of brnches per plant, all 10 crosses exceeded the parental average and 8 crosses showed grater number of branches per plant than better parents. All the 10 crosses showed high degree of heterosis and heterobeltiosis in the number of pods per plant and the maximum increase over better parent was 7%. The performance of F_1 for pod length was similar to that of parental average and better parents. Pod setting density of all 10 hybrids was high degree of heterosis and heterobeltiosis of parental average and better parents. Some degree of heterosis and heterobeltiosis were observed in seed seeting rate only in 7 crosses. All the 10 hybrids produced higher garin yield than higher parent and the maximum increase over higher parent was 67%. Hybrids between early parent and late parent showed late flowering and falling blossoms date. However, in a crosses betwen late parents, the F_1 flowered 2 days earlier than the parents.
