땅콩의 초형, 재배양식에 따른 생육특성을 구명하고저 Virginia 소립, Virginia 대립, Spailish, Valencia, Shinpung type의 5초형에 속하는 10품종을 공시, 재배양식 2수준(피복, 무피복)으로 하여 시험을 실시하였든 바 그 결과를 요약하면 다음과 같다. 1. 주경장은 피복, 무피복 모두 Valencia, Spanish, Virginia 소립, Shinpung. Virginia대립 순이었으며 피복재배를 함으로써 무피복재배보다 주경의 최고신장기를 20일 단축시켰다. 2. 분지수는 피복재배에서 Virginia소입 28개, Virginia 대립 27개. Shinpung 15개, Spanish 13개, Valencia 7개이었으며, 무피복재배의 경우 Virginia소립 22개, Virginia 대립 21개, Spanish, Shinpung 12개, Valencia 5개로 재배양식은 물론 초형간의 차이를 보였다. 3. 최장분지장은 피복, 무피복재배에서 Valencia, Spanish, Shinpung, Virginia대립, Virgnia소립 순으로 Valencia type 이 가장 길었다. 4. 주경절수는 초형이나 재배양식을 막론하고 대개 20∼30절로 비교적 안정된 생육특성이었다.

This study was conducted to investigate the growth characteristics for each of botanical types of peanut (Arachis hypogaea L.) under vinyl-and non-mulching in cultural limiting region. Ten peanut varieties pertaining to virginia-large seed, virginia-small seed, spanish, valencia, shinpung type were used in this study. Main stem length was in order of valencia, spanish, virginia-small seed, shinpung, virginia-large seed type under vinyl-and non-mulching. By vinyl-mulching, the maximum growth stage of main stem was shortened by 20 days than that of non-mulching. Number of branches per plant was distinguished among botanical types. Numbers of those were virginia-small seed 28, virginia-large seed 27, shinpung 15, spanish 13, valencia 7 under vinyl-mulching and were virginia-small seed 22, virginia-large seed 21, spanish 12, spinpung 12, valencia 5 under non-mulching. The longeset branch length was in order of valencia, spanish, spinpung, virginia-large seed, virginia-small seed type under vinyl-and non-mulching and velencia type was the longest of the botanical types.
