Abstract

This research was carried out to obtain the field resistance to disease and pest, and high yielding of new Boxthorn (Lycium chinense Mill.) varieties. Growth characteristics, yield potential, correlation of trait which was related the yield and path coefficient of the domestic native varieties. two of cultivated varieties and four of introduced varieties were investigated. In growth characters of collected varieties, the stem length of collected varieties in China were slightly long. Leaf area in Jindo, Kumsan native and Yusong 1 and 2 were wider than that of other varieties. Resistance to pest iniury was very strong at China 1, Japan 1 and Yusong 2 in eriophyidmite, and also resistance to anthrax anthracnose were showed less than 10% of the rate of attack fruit at Japan 1 and China 1. Flowering stage was more early in Chungyang native than that of other varieties. Fruit size of Kumsan native, Yusong 2 were large size fruit varieties. Fruit setting number was most abundant at 1,623 in Yusong 2 which was collected variety. And dry yields of fruit per lOa was more cmparatively abundant in Yusong 2 at 86% than those of Chungyang native. The high correlation cofficienct character with fruit yield were fruit setting and branching number and leaf area. Direct effect by path anaslysis were fruit setting number (Py=0.45), and branching number was showed indirect effect.

내병충(耐病蟲), 다수성(多收性) 구기자(拘杞子) 신품종(新品種)을 육성(育成)하기 위한 자료(資料)를 얻기 위하여 국내재내종(國內在來種) 5종(種), 육성종(育成種) 2종(種), 도입종(導入種) 4종(種)에 대하여 생육(生育) 특성(特性)과 수양성(收量性) 및 형질(形質) 과의 상관(相關), 경노계수(經路係數)를 조사(調査)하였던 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 수업종(蒐業種) 생육특성(生育特性)의 경장(經長)은 중국(中國) 수집종(蒐集種)이 $119{\sim}133cm$로 비교적(比較的) 큰 편이었고 분지수(分枝數)는 유성(儒城) 1호(號)가 많았으며 엽(葉)은 진도재내(珍島在來), 금산재내(錦山在來), 유성(儒城) 1호(號) 유성(儒減) 2호(號) 등(等) 이 광엽(廣葉)이었다. 2. 구기엽(枸杞葉)의 혹응애는 유성(儒城) 2호(號), 중국(中國) 1호(號), 일본(日本) 1호(號) 등(等)이 강(强)한 편이었으며, 과실(果實)분의 탄저병(炭疽病)은 일본(日木) 1호(號), 중국(中國) 1호(號) 등(等)이 10%미만(未滿)의 리병흑률(罹病黑率)을 보였다. 3. 개화기(開花期)는 청양재내(靑陽在來)가 빠른 편이었으며 1과당(果當) 종자수(種子數)는 중국(中國) 1호(號)가 30.5개(個)로 많았고 과육비률(果肉比率)은 영갱(寧更)가 높았다. 과실(果實) 크기 와 100과중(果重)은 금산재내(錦山在來), 유성(儒城) 2호(號)가 크고 무거웠다. 4. 1주당(株當) 과실(果實)의 착과수(着果數)는 유성(儒城) 2호(號)가 1,623개(個)로 수집종중(蒐集種中)에서 가장 많았으며 10a당(當) 건과(乾果) 수양(收量)은 청(靑) 양재내(陽在來)(152kg/10a)에 비하여 유성(儒城) 2호(號)가 86% 증수(增收)되 었다. 5. 과실(果實) 수량(收量)과 상관(相關)이 높았던 형질(形質)은 착과수(着果數), 분지수(分枝數), 엽(葉)크기였으며, 경노계수(經路係數) 분석(分析)에 의한 직접효과(直接效果)가 큰 것은 착과수(着果數)(Py=0.45) 였다.
