長水 白映山(흰 산철쭉 Rhododendron yedoense Maximowicz var. Poukhanence Nakai) 自殖에 의한 次世代 形質發現에 關한 硏究 = Studies on the phenotypic expression of first filial generattion by selfing of Rhododendron yedoense Maximowicz var. Poukhance Nakai in Jangsu Gun

1945年 全北 長水郡 山西面 雙溪里 馬坪 뒤 上端山 마치재 頂上에서 白色 산철쭉을 發見하였다가 1960年에 採取하여 裡里에 移植後 1987年 人工自家受精하여 次世代植物의 形態的 特性을 調査한 結果는 다음과 같다.
1. 150授紛花中 20花가 結삭하여 13.3%이였고, 200個의 種子中 108個體가 發芽하여 發芽率은 54%이였다.
2. 自家受精 次世代植物들은 白色花가 58株, 白色花가 34株로 出現하였다.
3. 開花期는 母本이 5月2日頃인데 比하여 次世代植物들은 母本과 같은 個體가 많았고, 母本보다 이르거나 늦은 個體도 상당수 있다.
4. 花辨의 크기는 母本보다 크거나 작은 것 또는 같고 특히 花辨이 6-7枚의 꽃도 있었으며 花托이 花辨花한 꽃도 있었다.
5. 雄예數는 母本과 같이 10個인 個體가 大部分이지만 7-9個인 個體도 있었다.

Rhododendron yedoense Maximowicz var. Poukhanece Nakai was discovered at the Machi Pass in Sanseomyeon, Jangsu-gun, Jeonlabug-do in 1945. It was transplanted at Iri in 1960 and was artificially self-pollinated in 1987. Morphological characteristics.
of the first filial generation by selfing were investigated with prioity given to flower.
The results are summerized as follows:
1. The rate of artificial self-pollintion was observed in 13.3%(20/150) and 200 seeds were obtained, and the rate of germination was 54%(108/200).
2. Flower colors of selfed kinese lines segregated from 58 white flowering plants and 34 pink plants.
3. Blooming day of motherplant was on May 2. Those of selfed lines mostly resembled to the motherplant but several lines bloomed earlier or later.
4. Petal size of selfed lines was observed longer or smaller than that of motherplant, petal number of selfed lines same or more in comparison with that of motherplant. Flower that tori varied with petal was observed.
5. Anther number of selfed lines was mostly 10 as that of parents, but it was rarely 7-9 in a flower.
