참당귀(當歸) 묘상기(苗床期)에서의 유묘특성(幼苗特性)과 추태율(抽苔率) 및 뿌리 수량(收量)과의 관계(關係)를 밝혀 유식물(幼植物) 시기(時期)에 조기검정(早期檢定)의 선발체계(選拔體系) 확립(確立)을 위한 기초자료(基礎資料)를 얻고자 시험을 실시한 결과는 다음과 같다. 1. 공시계통간(供試系統間) 묘초장(苗草長), 엽장(葉長), 엽병장(葉柄長) 등 지상부(地上部) 유묘특성(幼苗特性)에 유의적(有意的)인 차이가 나타나 묘상(苗床)에성의 조기검정(早期檢定) 가능성을 보였다. 2. 성숙기(成熟期)의 추태율(抽苔率)은
This study was conducted to obtain the basic information on setting up selection procedure using seedling characteristics in Angelica gigas Nakai lines. Morphological characteristics of the seedlings including height, leaf and petiole length among lines tested showed difference significantly, meaning that earlier selection was possible. Bolting rate at maturity ranged from 0.6 to 74.6% and root yield did from 350 to 3,893kg/ha. Root yield was increased in the lines with below 5% bolting rate. Heritabilities of petiole length, seedling height and leaf length in seedling stage bolting rate and root yield were high, while those of leaf length, root diameter and root length were relatively low. Bolting rate at maturity was positively correlated with seedling height, leaf length, leaf width, petiole length and number of leaves. A highly significant negative correlation was showed between root yield and seedling height, leaf length and width, petiole length, number of leaves, root length or bolting rate. From the above results the selection markers were found to be height, leaf length and petiole length in seedling stage.
